Families planning half-term activities and commuters weighing umbrella decisions will find the most reliable data from official sources that update continuously throughout the day. The following forecast synthesises information from multiple meteorological authorities to give a comprehensive picture of conditions in London over the next ten days.

Whether visitors are packing for a short break or residents are organising garden plans, understanding the rhythm of this unsettled period helps everyone make the most of whatever sunshine breaks through.

What is the 10 day weather forecast for London?

• Showers or rain are probable on every day through May 12, with precipitation probability ranging from 25% to 96% depending on the source and hour
• Temperatures will mostly sit between 15°C and 20°C during daylight, dropping to between 7°C and 14°C after dark
• Winds will remain light at 3–9 mph, blowing from the south-west, north-east or east depending on the day
• UV levels are moderate, rated between 2 and 5 on the standard index, meaning sunscreen is advisable during sunny breaks
• RealFeel temperatures are consistently 1–7°F cooler than the actual air temperature when standing in shade, due to wind chill and humidity
• No severe weather warnings have been issued by the Met Office for the period
• Forecasts become less reliable beyond ten days, with one long-range source suggesting cooler conditions by mid-May with highs of 13–16°C

What is the Weather London 7 days forecast?

The immediate week ahead presents classic early May conditions for the capital. Today brought sunny intervals with temperatures reaching around 17°C, though a breeze from the west-south-west kept things feeling closer to 16°C. Rain remained unlikely through the afternoon, with any precipitation holding off until the evening at earliest.

Monday shifts the pattern noticeably. Meteorologists at AccuWeather and the Met Office both indicate cloud building through the morning, with showers or rain likely by the afternoon. The chance of precipitation ranges from 45% to 84% depending on the forecast model consulted. Highs could reach 20°C in any sun breaks, but the overall feel will be cooler and damp.

How accurate are the hourly forecasts?

Hourly breakdowns give the sharpest guidance for planning specific activities. This afternoon, temperatures should hold at 17°C until around 4 PM before dipping to 14°C by early evening. Wind speeds of 6–9 mph will persist, making exposed areas feel noticeably chillier.

Rain probability jumps from around 10% in the early afternoon to 20% by evening, though these figures represent the chance of measurable precipitation occurring somewhere in the city rather than at any single point. Those with outdoor plans should monitor updates as the day progresses.

What should I pack for London weather this week?

Layering remains the safest strategy. A light waterproof jacket or umbrella serves well across most days, while a warmer layer becomes useful from Thursday onwards when overnight lows dip to 7°C in some forecasts. Sunglasses prove worthwhile during the frequent sunny intervals, particularly on Tuesday, Friday and Saturday when cloud breaks are most likely.

What is the London weather forecast 14 days?

Extending the view to two weeks reveals continued variability. The Met Office provides detailed guidance out to ten days with reasonable confidence, while The Weather Network offers longer-range projections that carry higher uncertainty.

The period from May 13 to May 17 shows a possible cooling trend. Highs may drop to between 13°C and 16°C, with showers remaining intermittent. This aligns with typical seasonal patterns for late spring in London, where cold Arctic air masses occasionally push southward to interrupt warmer spells.

Why do 14-day forecasts differ between sources?

Forecast models process atmospheric data differently, leading to variations in predicted temperatures and precipitation chances. The Met Office uses the UK-specific Unified Model, while international services may rely on European or American global models adapted for UK conditions. As information is updated continuously, earlier projections can shift significantly as new data arrives.

What causes this unsettled pattern?

London sits at the meeting point of several air masses at this time of year. Maritime air from the Atlantic brings moisture and cloud, while continental high pressure occasionally pushes in from the east or south-east to clear skies. Neither pattern has established dominance recently, resulting in the mixed conditions seen across the current forecast period.

What does the London weather 15 days forecast show?

Forecasts extending to 15 days and beyond operate under fundamentally different conditions. The further ahead meteorologists look, the more variables come into play, reducing the reliability of specific temperature readings and precipitation percentages. A general consensus does emerge from the available data.

The AccuWeather 15-day projection and readings from The Weather Network both suggest temperatures around 13–16°C by mid-May, with shower activity continuing. This would represent a return to cooler conditions compared with the current 17–20°C range.

Is there a risk of storms over the next two weeks?

No severe weather warnings cover the current ten-day window, according to the Met Office. Thunderstorms appear in some short-range forecasts for Monday, with AccuWeather reporting a 84–96% chance of showers and thunder for Sunday, though these figures apply to the overall probability across the day rather than sustained activity.

Residents following storm developments should consult resources such as the Met Office Storm Amy – Dates, Path and Impacts page for context on naming conventions and impact assessments for significant systems affecting the UK.

What does pollen count look like?

Pollen levels are currently low across London, according to the Met Office hourly forecast. Grass pollen season typically builds through May and June, so allergy sufferers should monitor updates as the month progresses.

When will London see the most sunshine this week?

Saturday 9 May currently appears the most promising day for extended sunshine, with partly cloudy conditions and temperatures reaching 19°C. The Met Office forecast shows Friday 8 May also offering cloud breaks, with highs near 18°C and relatively low precipitation risk.

Today, Sunday 3 May, continues to feature sunny intervals, with the best of the brightness expected through the middle of the afternoon. Monday turns mostly cloudy, reducing sunshine significantly despite the potential for warmer temperatures if breaks occur.

For those planning outdoor photography or sightseeing, the morning hours generally offer more stable conditions than afternoons during this unsettled spell, with cloud bubbles tending to develop and bring showers as the day warms.

What weather conditions are most likely across the coming days?

How does this weather compare to typical May conditions in London?

London’s average high for early May sits around 16–17°C, with average lows of 8–9°C, according to long-term climate data. The current forecast broadly aligns with these seasonal norms, with temperatures slightly above average on some days (reaching 19–20°C) and slightly below on others (dropping to 14°C).

Rainfall in May averages around 50–60mm for the month. The current unsettled pattern suggests London is on track for near-normal precipitation totals through the first couple of weeks, though individual days may see heavier bursts during shower activity.

Sunshine hours increase markedly through May as days lengthen toward the summer solstice. Even with the current cloud cover and showers, London can expect around 6–7 hours of bright sunshine per day on average, with Tuesday and Saturday likely to exceed this figure.

What are the main forecast sources for London weather?

Several established meteorological services provide London forecasts with different strengths. The BBC Weather service offers a straightforward day-by-day breakdown with hourly detail, making it accessible for quick lookups. The Met Office, as the UK’s official weather service, provides government-verified data with particular focus on hazards and warnings.

AccuWeather offers extended detail including RealFeel temperatures and UV indices, useful for those planning outdoor activities with precise comfort considerations. Netweather, a UK-focused service, provides comprehensive ten-day outlooks with snowfall risk and feels-like temperatures.

“RealFeel temperatures account for the combined effect of heat, humidity, cloud cover and wind to indicate what conditions actually feel like to the human body.” — AccuWeather meteorological standards

What comes next for London weather?

The most reliable forecast window covers the next five days, with confidence declining progressively beyond that period. Monday brings the highest rain probability of the coming week and a possibility of thunder, making indoor backup plans advisable for any outdoor events.

Through the middle of the week, temperatures hold steady in the mid-to-high teens with shower risks fluctuating between 25% and 70%. The weekend offers marginally better conditions, particularly Saturday, though cloud and occasional rain remain probable.

For those planning beyond the ten-day horizon, the emerging signal suggests cooler, more unsettled conditions may establish themselves by mid-May. Monitoring updates from the Met Office and Weather in Nottingham Tomorrow – Met Office Hourly Forecast provides context for regional patterns that often influence London conditions.
