The Met Office London weather forecast serves as the authoritative source for millions of residents, commuters, visitors, and businesses planning activities across the capital. Whether you need to know if rain will disrupt your commute, whether temperatures will require an extra layer, or how wind gusts might affect travel plans, understanding the Met Office’s detailed hourly forecasts, seven-day outlooks, and long-range predictions empowers better decision-making. This comprehensive guide explains how to read Met Office forecasts, what the current week ahead holds for London, seasonal weather patterns affecting the capital, how weather warnings work, and practical strategies for planning around London’s notoriously unpredictable climate.
London’s weather influences everything from transport delays to outdoor event planning, heating costs to health conditions exacerbated by cold or damp. The Met Office employs sophisticated modeling combining satellite data, weather station observations, supercomputer calculations, and meteorological expertise to produce forecasts updated multiple times daily. However, forecasts are probability statements rather than certainties, particularly beyond three days. Understanding forecast confidence levels, terminology like “sunny intervals” versus “sunny spells,” and how to interpret precipitation chances prevents misunderstandings that lead to poor planning decisions.
Current Met Office London Weather Forecast for the Week Ahead
The Met Office London weather forecast for the period from October 28 through November 3, 2025 shows typical autumn conditions with changeable weather bringing sunshine and showers, occasional rain, breezy winds, and temperatures ranging from 7°C overnight lows to 15°C daytime highs. The forecast demonstrates autumn’s characteristic variability, where weather systems move quickly across the UK, bringing periods of rain followed by clearer interludes.
Monday, October 28 brings plenty of sunshine throughout the day with scattered cloud developing during the morning, though most areas remain dry. Breezy conditions persist for much of the day before winds slowly ease through the afternoon. The maximum temperature reaches 15°C feeling like 12°C due to wind chill. The day offers the best weather of the week with prolonged sunny spells ideal for outdoor activities. Cloud builds into the evening after a clear start, with outbreaks of showery rain developing through the night. Minimum temperature falls to 9°C with gentle breezes and precipitation chances increasing to 70 percent by morning.
Tuesday, October 29 turns cloudy with outbreaks of rain lasting much of the day, some perhaps heavy at times. The wet weather persists from morning through afternoon before becoming clear overnight as rain clears eastward. Maximum temperature reaches just 13°C with feels-like temperatures of 11°C due to combined wind and moisture. Precipitation probability peaks at 90 percent around midday, with rain accumulation making this the wettest day of the week. Gentle breezes from the west-southwest accompany the rain. Overnight, temperatures fall to 8°C with clearing skies and diminishing precipitation chances dropping below 5 percent by dawn Wednesday.
Wednesday, October 30 starts dry and bright with clear skies and temperatures around 7°C at dawn, the coldest morning of the forecast period. Daytime brings increasing cloud from the south with maximum temperatures reaching 13°C and feels-like temperatures of 11°C. Light winds initially give way to gentle breezes building from the south. Precipitation chances remain low through morning and midday at less than 10 percent, but rain arrives from late afternoon with chances increasing to 50 percent by midnight. The day offers a narrow window of dry weather between Tuesday’s rain and overnight precipitation developing Wednesday evening.
Thursday, October 31 sees rain continuing from overnight with heavy precipitation through early morning. Outbreaks of rain persist with 70 percent precipitation probability through morning, gradually clearing from the northwest during afternoon. Maximum temperature reaches 15°C despite the wet conditions, with feels-like temperatures of 13°C. Wind speeds increase slightly with gentle to moderate breezes from the south-southwest. Evening and overnight conditions improve as rain clears, though scattered showers remain possible with 50 to 60 percent precipitation chances. The Halloween forecast suggests trick-or-treating may be damp early evening before drier conditions develop after 8 pm.
Friday, November 1 brings unsettled conditions with outbreaks of showery rain throughout the day as the next weather system moves through. Precipitation chances range from 30 to 80 percent depending on time, with highest rain probability during the morning commute at 5 to 7 am. Maximum temperature reaches 13°C with feels-like temperature around 10°C as brisk winds combine with moisture. Wind speeds increase with gusts reaching 28 mph making it the windiest day of the forecast period. Visibility remains very good to excellent between showers. Overnight temperatures fall to 10°C with continued shower activity and strong southwest winds persisting.
Saturday, November 2 offers mostly dry and bright conditions though strong gusty winds continue with coastal gales possible along the Thames Estuary. Maximum temperature around 12°C with feels-like temperature of 10°C due to wind chill from sustained 8 to 10 mph winds gusting to 17 to 19 mph. Precipitation chances range from 10 to 40 percent, with scattered showers possible particularly during morning and evening but extended dry periods allowing outdoor activities with appropriate wind protection. The breezy conditions suit kite flying, sailing, and other activities benefiting from moderate winds, though outdoor dining or events requiring gazebos face challenges from gusts.
Sunday, November 3 continues the theme of mostly dry and bright weather with strong winds persisting. Maximum temperatures reach 13°C with feels-like temperatures of 11°C. Gentle to moderate breezes from the south-southwest continue with gusts around 15 to 19 mph. Precipitation probability ranges from 10 to 40 percent concentrated during morning and evening periods. The day offers reasonable conditions for outdoor plans, though wind remains a consideration for activities sensitive to breezy conditions.
Understanding Met Office Forecast Terminology
Interpreting Met Office London weather forecasts requires understanding specific terminology meteorologists use to communicate weather conditions, probabilities, and confidence levels. Misunderstanding these terms leads to planning errors when forecasts are interpreted too literally or optimistically.
Sunny spells versus sunny intervals distinguish between longer and shorter periods of sunshine. Sunny spells indicate extended sunshine lasting 30 minutes or more between cloud cover. Sunny intervals suggest briefer sunshine breaking through clouds for 10 to 20 minutes before clouds obscure the sun again. The distinction matters for activities like photography requiring sustained bright conditions versus simply enjoying some sunshine during walks.
Showers differ fundamentally from rain in duration and coverage. Showers are localized, short-duration precipitation typically lasting 5 to 30 minutes before moving on or dissipating. An area forecast for showers may see rain at some locations while others a kilometer away remain dry. Rain indicates more widespread, longer-duration precipitation where most locations within the forecast area experience wet conditions for extended periods measured in hours rather than minutes.
Light winds, gentle breezes, moderate breezes, fresh breezes, and strong winds follow the Beaufort scale categorizing wind speeds. Light winds measure under 7 mph, producing smoke drift but barely moving leaves. Gentle breezes range from 7 to 12 mph, rustling leaves and moving small twigs. Moderate breezes of 13 to 18 mph raise dust and small branches move. Fresh breezes of 19 to 24 mph move small trees. Strong winds of 25 to 31 mph see large branches swaying and whistling through wires. Understanding these categories helps assess whether winds affect outdoor plans, with strong winds disrupting outdoor dining, cycling, and construction activities.
Chance of precipitation percentages represent probability that measurable precipitation falls at any point within the three-hour forecast period for that location. A 40 percent chance does not mean 40 percent of the area sees rain or that rain falls for 40 percent of the time period. It means four in ten times when this atmospheric setup occurs, measurable precipitation falls. Chances below 30 percent suggest rain is unlikely though possible. Chances of 30 to 70 percent indicate genuine uncertainty where rain may or may not occur. Chances above 70 percent suggest rain is likely though brief dry periods remain possible.
Feels like temperature combines actual air temperature with wind chill and humidity effects to represent how the temperature actually feels to human skin. Wind removes the insulating layer of warm air surrounding the body, making temperatures feel colder than thermometer readings indicate. High humidity makes warm temperatures feel hotter by impeding evaporative cooling from perspiration. Winter temperatures of 5°C might feel like 2°C with strong winds, requiring warmer clothing than temperature alone suggests. Summer temperatures of 28°C might feel like 32°C with high humidity, increasing heat stress and cooling needs.
Visibility categories including good (10 to 20 kilometers), moderate (4 to 10 kilometers), poor (1 to 4 kilometers), and very poor (under 1 kilometer) describe how far one can see horizontally. Excellent visibility exceeding 20 kilometers enables seeing distant landmarks like Alexandra Palace from central London. Poor visibility below 4 kilometers affects aviation, creates hazardous driving conditions, and disrupts outdoor photography. Fog produces very poor visibility requiring extreme driving caution and flight delays.
UV index measures ultraviolet radiation intensity on a scale from 0 (low) to 11+ (extreme). London’s October UV levels typically rate low (1 to 2) requiring minimal sun protection. Summer peaks reach moderate to high (6 to 7) requiring sunscreen, hats, and midday shade. Understanding UV index prevents sunburn and long-term skin damage, with protection needed whenever index reaches 3 or above.
Seven-Day Forecast Confidence and Accuracy
Met Office seven-day forecasts for London demonstrate decreasing accuracy as forecast lead time extends. Day 1 to Day 3 forecasts achieve approximately 85 to 90 percent accuracy for temperature within 2°C and precipitation occurrence. Day 4 to Day 5 accuracy drops to 70 to 80 percent. Day 6 to Day 7 forecasts carry substantial uncertainty, accurate perhaps 60 to 70 percent for general conditions but unreliable for specific details like timing of rain or exact temperatures.
The Met Office updates London forecasts multiple times daily as new observational data becomes available and computer models recalculate predictions. Morning forecasts issued around 6 am incorporate overnight observations. Midday updates around 1 pm refine afternoon and evening predictions. Evening forecasts near 6 pm provide next-day outlooks. Checking forecasts twice daily, morning and evening, ensures access to most current predictions rather than relying on forecasts issued 12 to 24 hours earlier that may be superseded by evolving atmospheric conditions.
Computer forecast models including the Met Office’s Unified Model, the European Centre for Medium-Range Weather Forecasts (ECMWF) model, and American GFS model sometimes disagree about London weather particularly beyond three days. When models converge on similar outcomes, forecast confidence increases. When models diverge substantially, meteorologists highlight uncertainty and provide broader ranges of possible outcomes. Noting whether forecasts express high or low confidence helps calibrate planning decisions.
Ensemble forecasting runs models multiple times with slightly varied initial conditions, generating a range of possible outcomes. If 90 percent of ensemble members predict rain on a particular day, confidence is high. If half predict rain and half predict dry conditions, genuine uncertainty exists that forecasts communicate through wider probability ranges or phrases like “rain possible” rather than “rain likely.” Understanding that forecasts express probabilities rather than certainties prevents frustration when weather deviates from predictions, particularly in the 4 to 7 day range where accuracy diminishes.
London’s urban heat island effect, Thames River influence, and elevation variations from river level to Hampstead Heath create microclimates that single-point forecasts cannot fully capture. Central London often runs 2 to 3°C warmer than outer suburbs, particularly overnight when urban surfaces release stored heat. Riverside locations experience higher humidity and morning fog. Elevated areas see cooler temperatures and occasionally different precipitation types with rain in low-lying areas while Hampstead receives sleet or wet snow. Recognizing local variations around general forecasts improves planning for specific London neighborhoods.
Met Office Weather Warnings for London
Met Office weather warnings alert the public when severe weather may cause disruption, damage, or danger. Understanding the three-tier color-coded warning system—yellow, amber, and red—enables appropriate protective actions based on impact severity and likelihood.
Yellow warnings indicate severe weather is possible over the next few days that could affect you. The warning suggests planning ahead thinking about possible travel delays or disruption of day-to-day activities. Yellow means monitoring developing weather situations and being aware that conditions may change or worsen. Most London weather warnings fall into the yellow category, issued for heavy rain causing localized flooding, strong winds potentially downing tree branches, snow and ice creating hazardous travel conditions, or fog reducing visibility below one kilometer.
Amber warnings signal increased likelihood of bad weather affecting you with potential disruption to plans, travel delays, road and rail closures, power interruptions, and risk to life and property. Amber means preparing to change plans and protecting yourself, family, and community from severe weather impacts. London receives amber warnings several times yearly, typically for exceptional rainfall threatening widespread flooding, very strong winds risking structural damage and dangerous flying debris, heavy snow paralyzing transport, or extreme heat creating health risks for vulnerable populations.
Red warnings represent extreme weather requiring action now to keep yourself and others safe. Widespread damage, travel and power disruption, and significant risk to life are likely. Red means avoiding dangerous areas and following advice from emergency services and local authorities. London rarely receives red warnings perhaps once per decade for events like the exceptional windstorms that struck in 1987 and 1990, or the extreme heat in July 2022 when temperatures approached 40°C.
Weather warnings are issued for specific impacts including rain and flooding, wind, snow and ice, fog, extreme heat, thunderstorms, and lightning. The Met Office considers both impact severity and probability when deciding whether to issue warnings. A major snowstorm predicted with 30 percent probability might warrant a yellow warning due to potentially severe impacts if snow materializes. Light snow predicted with 90 percent probability might not warrant warnings if impacts are minimal. The warning decision balances alerting the public against warning fatigue from excessive low-impact alerts.
London weather warnings typically cover Greater London as a single geographic unit, though sometimes distinguish between central, west, north, south, and east London sub-areas when impacts vary spatially. Warnings specify validity periods showing when severe weather is expected to begin and end. Checking warnings when planning travel or outdoor activities prevents being caught unprepared by forecast deteriorating conditions. The Met Office distributes warnings through their website, mobile apps, broadcast media, social media, and weather apps that incorporate Met Office data.
As of October 28, 2025, no weather warnings are in force for London or the wider UK, indicating that forecast conditions through the next five days, while including periods of rain and wind, remain within normal autumn parameters not warranting alert status. The changeable conditions forecast for the week ahead represent typical seasonal weather rather than exceptional events requiring public warnings.
Seasonal Weather Patterns Affecting London
London’s position at 51.5°N latitude in the southeast corner of England creates moderate maritime climate characterized by cool winters, mild summers, and year-round precipitation distributed relatively evenly across months. Understanding seasonal patterns helps contextualize weekly forecasts within broader climate norms and plan activities accounting for typical conditions.
Autumn (September through November) brings declining temperatures, increasing rainfall, strengthening winds, and daylight diminishing from 13 hours in early September to just 8 hours by late November. October averages daytime highs of 14 to 15°C and overnight lows of 8 to 9°C, closely matching current forecast temperatures. Rainfall averages 58 to 68mm across October distributed over 13 to 15 wet days, meaning rain falls on roughly half of days though rarely all day. Autumn sees transitional weather as the jet stream becomes more active, steering Atlantic weather systems across the UK bringing changeable conditions alternating between sunny spells and showers.
Winter (December through UK Snow Forecast 2025: Latest News & Winter PredictionsFebruary) produces London’s coldest and potentially most disruptive weather, though snow remains relatively rare compared to northern UK regions. January averages 2 to 8°C with occasional cold snaps dropping below freezing for several consecutive days. Snow falls on average 12 to 15 days per winter, though accumulations exceeding 5cm occur just once or twice. Ice presents greater hazards than snow, forming overnight on pavements, roads, and cycle paths when temperatures drop below zero following rain or melting snow. Winter sees shortest days with just 7 to 8 hours of daylight in late December creating long periods of darkness and reduced vitamin D production.
Spring (March through May) brings gradually warming temperatures, increasing daylight, and typically the driest season of London’s year. March remains cool at 7 to 12°C but by May temperatures reach 11 to 19°C. Rainfall averages 40 to 50mm monthly, somewhat lower than autumn and winter totals. Spring weather can be highly variable with warm southerly flows bringing 20°C days in April followed by Arctic blasts dropping temperatures back to 5°C within 48 hours. The season produces dramatic temperature swings requiring flexible clothing and heating strategies.
Summer (June through August) delivers London’s warmest conditions averaging 19 to 24°C, though heatwaves occasionally push temperatures above 30°C for several consecutive days. The July 2022 heatwave saw London reach 40.3°C at Heathrow, the UK’s hottest temperature on record. Summer rainfall averages 45 to 55mm monthly often falling as intense thunderstorms producing brief heavy downpours rather than prolonged rain. Humidity increases during summer creating muggy uncomfortable conditions particularly in the Underground where temperatures can exceed 35°C. Summer also sees longest daylight extending to 16 hours in late June enabling extended outdoor activities.
Understanding climate normals helps assess whether forecast conditions represent typical seasonal weather or notable deviations. The current October forecast showing 7 to 15°C temperatures, multiple rain days, and breezy winds aligns closely with October climate norms. Forecasts showing sustained temperatures above 18°C or below 5°C for October would represent atypical conditions worth noting. Forecasts predicting several consecutive dry days or alternatively persistent rain lasting three or more days would deviate from typical October changeability.
Climate change is gradually altering London’s seasonal patterns. Average temperatures have increased approximately 1°C since preindustrial times. Heatwaves have become more frequent and intense. Winter cold snaps have become less severe though extreme events still occur. Autumn and winter storms have intensified with more frequent instances of damaging winds. Rainfall patterns show increasing variability with more frequent heavy downpours interspersed with longer dry periods. These long-term trends gradually shift what constitutes “normal” weather, though year-to-year variability often exceeds the climate change trend in any given season.
Long-Range Outlook: November and Beyond
The Met Office’s long-range outlook for early November 2025 through mid-November indicates changeable and at times unsettled weather likely continuing, with low pressure dominating the UK and surrounding regions. This pattern brings further showers or longer spells of rain at times, with all parts potentially seeing heavy rain though western areas will likely be wettest. Brief drier or clearer interludes are expected, most prevalent in eastern regions including London.
Strong winds feature prominently in the outlook with gales or severe gales possible particularly affecting coastal areas and potentially disrupting ferry services, outdoor events, and sensitive infrastructure. With winds predominantly blowing from westerly or southwesterly quadrants, above average temperatures are more likely, especially early November, with reduced incidence of overnight frost and fog compared to normal. The mild, windy, unsettled pattern reflects persistent Atlantic influence rather than settled high pressure or cold easterly flows.
The second half of November shows increasing probability of dry and fine weather, though some overnight fog and frost may develop. Any wetter spells are most likely to affect northern UK regions while London and the southeast may see longer dry intervals and occasional anticyclonic conditions bringing calmer, clearer weather. However, long-range outlooks beyond 10 to 14 days carry substantial uncertainty, representing general tendencies rather than specific forecasts. Multiple atmospheric patterns remain possible, and outcomes may deviate significantly from central predictions.
Monthly and seasonal outlooks published by the Met Office provide probabilistic guidance about whether temperatures and rainfall will likely be above, near, or below average for the time of year. These outlooks guide energy sector planning, agricultural decisions, and corporate risk management but lack the precision needed for individual event planning. Checking monthly outlooks provides context for whether the coming weeks favor settled versus unsettled patterns, though specific day-by-day details remain unpredictable beyond seven days.
Practical Planning Strategies for London Weather
Effectively managing London’s changeable weather requires flexible planning strategies accounting for forecast uncertainty while minimizing disruption when conditions deteriorate unexpectedly. The following approaches help Londoners navigate weather variability.
Layer clothing rather than relying on single heavy coats enables adapting to temperature variations throughout the day. Autumn and spring see morning temperatures of 7 to 10°C warming to 14 to 18°C by afternoon, a range that single-layer outfits cannot comfortably cover. Starting with a base layer, adding an insulating mid-layer, and topping with a weather-resistant outer shell allows removing or adding layers as conditions change. Carrying a small backpack stores shed layers during warm periods for re-donning when temperatures drop or rain develops.
Always carry rain protection regardless of morning conditions during autumn through spring when showers develop with minimal warning. Compact umbrellas or packable waterproof jackets stuff into bags occupying minimal space while providing protection when unexpected showers strike. Londoners learn that “partly cloudy” forecasts often produce brief showers, and even “mostly dry” predictions occasionally bring surprise precipitation. The modest inconvenience of carrying rain gear prevents arriving drenched at destinations.
Plan outdoor activities during forecast dry periods rather than hoping rain holds off during predicted wet spells. When forecasts show Tuesday wet and Wednesday dry, schedule outdoor errands, sports, or leisure activities for Wednesday rather than gambling on Tuesday improving. While forecasts beyond three days carry uncertainty, they provide sufficient guidance to prefer days with lower precipitation probability over those with higher chances. Building flexibility into plans enables shifting activities to better weather windows when forecasts evolve.
Monitor forecasts twice daily rather than relying on checks days in advance ensures access to most current predictions as atmospheric conditions evolve. Morning checks around 7 am inform same-day decisions about commute routes, whether children need waterproof gear for school, and afternoon plans. Evening checks around 6 pm update next-day outlooks enabling clothing preparation and schedule adjustments. Forecast changes between morning and evening indicate evolving weather systems requiring revised planning.
Use transport alternatives during adverse weather prevents being stranded when heavy rain, high winds, or snow disrupt services. During predicted severe weather, avoiding National Rail services particularly overground routes through tree-lined areas reduces exposure to wind-related delays and cancellations. The London Underground, while crowded and uncomfortable, operates more reliably during surface weather than surface transport. Buses face traffic delays during rain but continue operating barring extreme conditions. Building extra commute time and having fallback routes prevents weather-related lateness.
Adjust heating and clothing for forecast temperatures rather than maintaining rigid indoor settings saves energy costs while maintaining comfort. When overnight temperatures are forecast at 12°C rather than 5°C, reducing or eliminating heating prevents overheating and wasted energy. Conversely, when cold snaps approach, preheating homes before temperatures plunge maintains comfort more efficiently than heating frozen spaces. Checking feels-like temperatures helps calibrate appropriate clothing thickness beyond simple thermometer readings.
Prepare homes for predicted storms by securing garden furniture, checking roof tiles, clearing gutters, and charging devices before forecast high winds prevents damage and ensures readiness if power outages occur. Most wind-related home damage results from inadequate preparation allowing loose items to become projectiles, blocked drains causing water ingress, or weak structures failing under increased loading. Thirty minutes of preparation before forecast storms prevents hours of cleanup and potentially thousands in damage costs.
How Weather Affects London Transport
London’s transport networks face varying weather vulnerabilities that forecasts help anticipate and mitigate. Understanding which weather conditions affect which transport modes enables smarter travel planning and alternative routing when forecasts predict disruption.
National Rail services suffer most weather-related disruption, particularly from autumn leaf-fall, high winds, heavy rain, and snow. Fallen leaves on rails reduce braking friction, requiring trains to run slower and leave longer gaps between services. Autumn sees “rail head treatment trains” attempting to remove leaf mulch, but disruption persists throughout October and November. High winds exceeding 50 mph trigger blanket speed restrictions across exposed routes and occasionally suspend services completely when wind-blown debris fouls tracks or overhead power lines. Heavy rain causes flooding at low-lying sections forcing service suspensions. Snow and ice affect points and electrical equipment causing widespread delays.
London Underground operates largely underground insulating it from surface weather, but exceptions create vulnerabilities. Overground sections of the Metropolitan, District, and Central lines face wind, snow, and ice affecting service. Heat causes rails to expand potentially buckling tracks, triggering speed restrictions when temperatures exceed 30°C. Cold causes equipment failures and frozen points. Despite these vulnerabilities, the Underground operates more reliably during weather than National Rail, making it the preferred option during forecast adverse conditions.
London buses face traffic congestion worsening during rain when more people drive rather than walk or cycle. Heavy rain reduces visibility and creates standing water hazardous for two-wheeled vehicles, pushing more commuters toward four-wheeled transport. However, buses themselves cope well with rain continuing services barring exceptional flooding. Strong winds rarely affect buses except on exposed routes where double-deckers occasionally experience crosswind stability problems. Snow and ice affect buses most severely, with routes on hills becoming impassable and side streets untreated. During forecast snow, major routes remain operational longest before gradual service reductions and suspensions.
Cycling faces weather-dependence that forecasts help manage. Rain makes cycling uncomfortable but not impossible with appropriate gear. Strong winds above 25 mph create genuine hazards pushing cyclists off balance particularly crossing bridges or emerging from building-sheltered streets into exposed areas. Forecast strong winds should deter casual cyclists though experienced riders may continue using protected routes. Ice presents extreme danger with even small patches causing falls potentially producing serious injury. When overnight temperatures drop below 3°C following rain or snow, cycling requires extreme caution or alternative transport selection.
Walking tolerates most weather barring extreme conditions. Rain requires waterproofs. Cold requires warm clothing. Fog and reduced visibility require heightened awareness at road crossings. Only exceptional weather including thunderstorms with lightning risk, flooding producing impassable pavements, or icy conditions creating fall hazards should deter walking. Forecasts help pedestrians dress appropriately and allow extra time when wind or rain will slow walking speeds.

How accurate are Met Office 7-day forecasts for London?
Met Office 7-day forecasts for London demonstrate decreasing accuracy as forecast lead time extends. Day 1 to Day 3 forecasts achieve approximately 85 to 90 percent accuracy for temperature within 2°C and correct precipitation occurrence. Day 4 to Day 5 accuracy drops to 70 to 80 percent with increasing uncertainty about timing and intensity. Day 6 to Day 7 forecasts carry substantial uncertainty, accurate perhaps 60 to 70 percent for general conditions like “rain likely” versus “staying dry” but unreliable for specific details like exact timing of rain onset or precise temperatures. The Met Office updates forecasts multiple times daily as new data becomes available, improving accuracy particularly for imminent periods. Checking forecasts twice daily morning and evening ensures access to most current predictions.
What do Met Office weather warnings mean?
Met Office weather warnings use a three-tier color-coded system. Yellow warnings indicate severe weather is possible that could cause disruption, suggesting you plan ahead and monitor forecasts for updates. Amber warnings signal increased likelihood of bad weather affecting you with potential for travel delays, power cuts, and risk to safety, meaning you should prepare to change plans and protect yourself and property. Red warnings represent extreme weather expected with widespread damage, disruption, and significant danger to life, requiring immediate action to stay safe and avoid affected areas. Warnings are issued for rain, wind, snow, ice, fog, extreme heat, thunderstorms, and lightning. As of October 28, 2025, no weather warnings are in force for London, indicating conditions remain within normal autumn parameters.
What is the best time to visit London weather-wise?
The best time to visit London for pleasant weather is late spring through early summer, specifically May through early July, when temperatures average 15 to 23°C, rainfall is moderate averaging 50 to 55mm monthly, and daylight extends to 14 to 16 hours daily. Late April and September also offer good conditions with temperatures of 12 to 19°C and lower tourist crowds than peak summer. Summer (July-August) delivers warmest temperatures averaging 19 to 24°C but also brings peak crowds, highest prices, and occasionally uncomfortable heat during heatwaves. Autumn (September-November) sees increasing rain and declining temperatures but features beautiful foliage and cultural seasons beginning. Winter (December-February) produces short days of 7 to 8 hours, cold temperatures averaging 2 to 8°C, and occasional snow, though festive lights and holiday markets create atmosphere despite weather challenges.

Subscribe to email or text alerts through the Met Office website for automatic notifications when warnings are issued for specified locations.
What does “feels like” temperature mean on Met Office forecasts?
Feels like temperature combines actual air temperature with wind chill and humidity effects to represent how the temperature actually feels on exposed human skin. Wind removes the insulating layer of warm air surrounding the body through forced convection, making temperatures feel colder than thermometer readings indicate. The formula accounts for wind speed and temperature producing feels-like values that can be 5 to 10°C lower than actual temperature during winter with strong winds. High humidity makes warm temperatures feel hotter by impeding evaporative cooling from perspiration. A summer day of 28°C with 80 percent humidity might feel like 32°C due to reduced cooling efficiency. Feels-like temperature helps determine appropriate clothing, assess heat stress or hypothermia risk, and understand actual outdoor comfort levels beyond simple thermometer readings.
Why does London weather change so frequently?
London weather changes frequently due to its position in the mid-latitudes where contrasting air masses meet and the jet stream regularly brings Atlantic weather systems across the UK. The jet stream’s position varies week to week and day to day, sometimes flowing directly over the UK bringing rapid succession of weather fronts with alternating rain and clear spells, other times diverting north or south allowing longer settled periods. London’s maritime climate on an island means weather systems approach from multiple directions—Atlantic westerlies bringing mild moist air, Arctic northerlies bringing cold air, continental easterlies bringing either hot dry air in summer or cold air in winter. The relatively small distances between different weather types mean systems move quickly across London, producing changeable conditions where morning sun gives way to afternoon showers or vice versa. This changeability persists year-round though intensifies during autumn and spring when the jet stream becomes most active.
How far ahead can London weather be accurately forecast?
London weather can be accurately forecast approximately 3 to 5 days ahead for general conditions and 1 to 3 days ahead for specific details. Day 1 forecasts predict temperature within 1 to 2°C and correctly forecast precipitation occurrence 85 to 90 percent of the time. Day 2 to Day 3 maintain similar accuracy though uncertainty increases for exact timing of weather changes. Day 4 to Day 5 forecasts remain reasonably accurate for overall patterns like “wet and windy” versus “dry and settled” but become unreliable for hourly details. Day 6 to Day 7 carry substantial uncertainty with accuracy around 60 to 70 percent for general conditions. Beyond 7 days, forecasts provide broad tendencies rather than specific predictions, useful for understanding whether unsettled or settled patterns are more likely but not for detailed planning. Monthly and seasonal outlooks extending weeks to months ahead indicate probability of above, near, or below average temperatures and rainfall but cannot predict specific daily conditions.
Does London get a lot of rain compared to other UK cities?
London receives less rainfall than most major UK cities despite its reputation for rain. London averages 583 to 624mm annually depending on specific location, significantly less than Manchester (867mm), Glasgow (1,124mm), Edinburgh (710mm), Belfast (846mm), or Cardiff (1,111mm). However, London’s rain falls across more days (approximately 120 to 140 wet days annually) in lighter amounts rather than concentrated heavy downpours. This frequent light rain pattern creates London’s damp reputation despite moderate total rainfall. London receives less rain than western UK regions due to being further from Atlantic moisture sources and sheltered by higher ground to the west. Southeastern England generally constitutes the UK’s driest region, with London wetter than areas further southeast but drier than most of England’s west, north, and Scotland.
What causes London’s urban heat island effect on forecasts?
London’s urban heat island effect makes central London temperatures 2 to 5°C warmer than surrounding countryside, particularly on calm clear nights when rural areas radiate heat efficiently to space while urban areas retain warmth. The effect arises from multiple factors: buildings and pavement absorb solar radiation during daytime and release it slowly overnight maintaining warmer temperatures, dark asphalt and concrete surfaces absorb more solar energy than vegetation or soil, lack of vegetation reduces evaporative cooling that moderates temperatures naturally, waste heat from buildings, vehicles, and industry adds warmth to the atmosphere, and urban canyons between tall buildings trap heat preventing it radiating to space. The effect peaks overnight and during heatwaves when urban areas remain oppressively hot while rural areas cool comfortably. Met Office forecasts for London reference specific locations, with forecasts for central London running warmer than outer suburbs particularly overnight. The urban heat island reduces frost frequency, modifies precipitation patterns, and affects heating and cooling energy demands.
How do I interpret precipitation probability on Met Office forecasts?
Precipitation probability represents the chance that measurable precipitation (0.1mm or more) falls at any point within the three-hour forecast period at your specific location. A 40 percent precipitation chance means four in ten times when this atmospheric setup occurs, measurable rain falls at your location. It does not mean 40 percent of the forecast area receives rain, nor that rain falls for 40 percent of the time period. Probabilities below 30 percent suggest rain is unlikely though not impossible; carry an umbrella if being caught in rain would cause significant problems. Probabilities of 30 to 70 percent indicate genuine uncertainty where rain may or may not occur; plan for either outcome. Probabilities above 70 percent suggest rain is likely though brief dry periods remain possible; assume wet conditions and plan accordingly. The timing indicated provides a three-hour window when rain is most likely but doesn’t specify exact start and end times within that window.
What should I do if Met Office issues an amber warning for London?
When the Met Office issues an amber warning for London, take it seriously as significant disruption is likely. Review the specific warning details including timing, expected impacts, and affected areas. Amber warnings indicate increased likelihood of travel delays with possible road and rail closures, power interruptions from infrastructure damage, flooding affecting properties and transport, and potential danger to life requiring protective actions. Postpone non-essential travel during the warning period as conditions may deteriorate quickly. Secure outdoor items like garden furniture, bins, and trampolines before forecast storms to prevent them becoming dangerous projectiles. Check transport services for disruption before traveling and allow significantly extra journey time. Charge electronic devices and ensure working torches and batteries in case of power cuts. Stock essential supplies including food, water, and medications to avoid going out during worst conditions. Follow advice from emergency services and local authorities including potential evacuation orders. Monitor forecast updates as warnings may be upgraded to red if conditions worsen or downgraded if threats diminish.
How does London weather affect seasonal allergies?
London weather significantly affects seasonal allergies by influencing when plants release pollen and how pollen disperses. Warm dry spring conditions trigger early pollen release from trees including birch, oak, and plane trees that dominate London’s urban forest. Wet cold springs delay pollen season and wash pollen from air providing temporary relief. Summer grass pollen peaks during warm dry June and July, with symptoms worsening when breezy conditions spread pollen widely while calm humid conditions trap pollen near ground level. Thunderstorms create “thunderstorm asthma” when strong winds break pollen grains into smaller fragments that penetrate deeper into lungs triggering severe reactions. Rain provides relief by washing pollen from air, but symptoms return once surfaces dry. Autumn weed pollen including ragweed affects some sufferers. Met Office pollen forecasts predict levels from low to very high based on weather conditions, pollen counts, and plant development stages. Check pollen forecasts alongside weather forecasts to plan outdoor activities and medication timing.
Why are London winters getting warmer according to Met Office data?
London winters are getting warmer due to global climate change driven by increasing atmospheric greenhouse gas concentrations from human activities. Met Office data shows London’s average temperatures have increased approximately 1°C since preindustrial times with winter warming particularly pronounced. The warming manifests through fewer days with frost and snowfall, milder average temperatures reducing heating demand, less frequent extreme cold snaps though they still occasionally occur, and earlier spring onset with plants budding and blooming several weeks earlier than historical norms. Winter warming affects energy consumption reducing heating needs but increasing winter air conditioning use during unusually mild periods, changes plant and animal seasonal cycles affecting ecosystems and agriculture, reduces winter sports opportunities as snow becomes rarer, and affects winter health with reduced cold-related deaths but changing infectious disease patterns. While year-to-year variability means individual winters may still be cold relative to recent decades, the long-term trend is unmistakably toward warmer conditions that will continue as atmospheric greenhouse gas concentrations rise unless emissions are dramatically reduced.
What’s the difference between Met Office and BBC Weather forecasts?
The Met Office produces the underlying weather forecast data that BBC Weather and many other UK forecast services use. BBC Weather accesses Met Office’s Unified Model output and presents it through their own graphics, website design, and broadcast segments. The core forecast information—temperatures, precipitation chances, wind speeds—should be identical whether viewing Met Office directly or through BBC Weather. Differences arise from presentation style with BBC Weather often simplifying forecasts for general audiences while Met Office provides more technical detail for weather enthusiasts and professional users. Update frequency may differ with Met Office updating continuously as new model runs complete while BBC Weather updates at scheduled intervals. BBC Weather includes additional features like personalized forecasts, weather news articles, and integration with BBC local radio forecasts. For most purposes, either source provides equally reliable London forecasts since both draw from the same Met Office modeling. Aviation, marine, and mountain users should access Met Office directly for specialized forecasts BBC Weather does not provide.
How do I access hourly London weather forecasts from Met Office?
Access hourly London weather forecasts by visiting metoffice.gov.uk and entering “London” in the location search box. Select “London (Greater London)” from results to view the detailed forecast page. The default view shows three-hourly forecasts; scroll down and select “Hourly forecast” tabs to expand detailed hour-by-hour predictions covering temperature, precipitation probability, wind speed and direction, visibility, humidity, UV index, and feels-like temperature. Hourly forecasts extend 48 hours ahead with data presented in scrollable tables. The Met Office mobile app provides similar hourly forecasts with the advantage of location-based automatic forecasts and customizable alerts. Third-party weather apps including Carrot Weather, Weather Underground, and others may incorporate Met Office data depending on region and licensing, though viewing directly through Met Office ensures official unfiltered forecasts. Hourly forecasts help plan specific activities by identifying rain-free windows between showers, peak wind times to avoid, or warmest/coolest hours affecting outdoor comfort.
Can I get weather forecasts for specific London neighborhoods from Met Office?
The Met Office provides weather forecasts for hundreds of UK locations including many specific London neighborhoods beyond the general “London” forecast. Search for specific areas like “Camden,” “Greenwich,” “Richmond,” “Hackney,” or “Wimbledon” on the Met Office website to access neighborhood-specific forecasts accounting for local variations. However, forecast resolution remains limited to approximately 2 to 5 kilometer grids, meaning truly street-level precision is not available. Microclimate effects from elevation, river proximity, urban density, and local topography create variations the forecast models cannot fully resolve. Riverside locations near the Thames experience higher humidity and morning fog. Elevated areas like Hampstead Heath or Crystal Palace see cooler temperatures particularly overnight. Dense central London runs warmer due to urban heat island effects. Using neighborhood-specific forecasts provides better accuracy than relying on the general Greater London forecast, but expect 1 to 2°C temperature variations and localized precipitation differences from broader area predictions.
What weather apps use Met Office data for London forecasts?
Many popular weather apps incorporate Met Office data for UK including London forecasts. The official Met Office Weather App provides direct unfiltered access to Met Office forecasts with features including location-based automatic forecasts, severe weather warnings, pollen forecasts, UV index, and customizable alerts. BBC Weather uses Met Office data presented through BBC’s interface and graphics. The Apple Weather app on iOS devices sources data from multiple providers including Met Office for UK locations. Other apps using Met Office data include NetWeather, Weather Pro UK, and UK Weather. However, data licensing and source integration vary, with some apps blending Met Office data with other sources or using proprietary algorithms that modify original forecasts. For guaranteed access to official Met Office forecasts without modification, use the Met Office’s own app or website directly. Check app settings or documentation to confirm whether Met Office data is used for your location, as many weather apps use different data sources for different countries.
How does London weather in October compare to other autumn months?
October weather in London represents mid-autumn transitioning from milder September conditions toward colder wetter November. Average October temperatures range from 8 to 15°C daytime and 6 to 10°C overnight, approximately 3 to 4°C cooler than September’s 12 to 19°C daytime. November further declines to 7 to 11°C daytime. October rainfall averages 58 to 68mm distributed over 13 to 15 wet days, similar to September but less than November which sees increasing rainfall as Atlantic weather systems intensify. October daylight shrinks dramatically from 11.5 hours early month to 9 hours by month end as the approach to winter solstice accelerates darkness. Compared to September, October sees notably shorter days, cooler temperatures requiring transitioning from light autumn clothing to warmer layers, and increasing prevalence of wind and rain versus September’s lingering summer warmth. Compared to November, October remains slightly milder and marginally less wet though differences are modest. October represents autumn’s midpoint when summer’s memory fades while winter’s arrival looms, creating characteristic mid-autumn changeability.
