What temperature will it be in London next week?

The Met Office provides point forecasts extending to 7 days for specific London locations, with regional outlooks covering an additional 5 days beyond that. For the coming week, the data shows temperatures hovering in the mid-to-high 50s Fahrenheit range, with Monday’s regional maximum reaching 16°C across South East England according to the Met Office South East England forecast.

Daily highs and lows

Current conditions vary significantly even within central London. Greater London registered 7°C with sunny skies in the next-hour forecast, feeling closer to 5°C due to a gentle breeze from the northeast, according to the Met Office Greater London forecast. Just a short distance away, the City of London showed 10°C with partly cloudy conditions, feeling like 9°C under an easterly wind, per the Met Office City of London forecast. This micro-regional variation means your exact location within the city can affect the temperature you experience by several degrees.

Precipitation chances

Rain probability remains low across all monitored London locations at under 5% for the immediate forecast period, verified across both Greater London and City of London point forecasts from the Met Office. Gust speeds consistently measure around 10mph, suggesting generally stable conditions without significant weather disruptions for outdoor plans.

Will it be warm in London tomorrow?

Tomorrow’s outlook shows a high of 57°F with mostly sunny conditions, giving Londoners and visitors a noticeably milder day than today’s cold start. The Met Office forecast for Greater London indicates clear nighttime conditions following tomorrow’s sunny periods, which should allow any accumulated warmth to dissipate by the following morning.

Tomorrow’s forecast details

The Met Office data for tomorrow (April 21) projects mostly sunny skies with temperatures reaching approximately 57°F during daylight hours before dropping to around 45°F overnight. Wind speeds remain gentle, with max gusts around 10mph, keeping the air movement comfortable without creating a significant wind-chill effect. This represents a typical spring transition day for London, where afternoon warmth balances against cooler morning and evening temperatures.

Temperature outlook

Looking further into the week, Tuesday shows partly sunny conditions with temperatures climbing toward 61°F according to available forecasts. The Met Office regional outlook for South East England notes a pattern of cold bright starts gradually becoming cloudier through afternoon hours, with isolated shower possibilities developing later in the day. This suggests layering remains advisable even as temperatures moderate.

What’s the weather like in London?

Right now, London is sitting in that grey-area between seasons where a sunny morning can give way to overcast skies by evening. The city’s position in South East England creates micro-climates that vary across neighborhoods, from the riverside chill of Southwark to the sheltered warmth of protected central districts.

Current conditions

As of the latest Met Office data, Greater London registered 7°C under sunny skies with a feels-like temperature of 5°C, while the City of London showed 10°C under partly cloudy conditions with a feels-like reading of 9°C, according to point forecasts from the Met Office City of London forecast page. The northeast wind in Greater London and easterly flow in the Square Mile contribute to these divergent readings despite the relatively short distance between them. Rain probability stays below 5% across both locations, and maximum gust speeds of 10mph indicate generally calm conditions.

Short-term trends

The regional Monday forecast from the Met Office South East England outlook describes a “cold and rather bright start” followed by increasing cloudiness through the morning and afternoon, with a chance of isolated showers developing later in the day. Maximum temperatures for the region are expected to reach 16°C, with light winds throughout. This pattern suggests Londoners should anticipate variable conditions rather than sustained sunshine or rain.

Is it too cold in London now?

The question of whether London is “too cold” depends entirely on what you’re used to and what you’re planning to do. For visitors from warmer climates, the current 42-57°F range might feel brisk, while those acclimated to northern European winters will find it relatively mild. Layered clothing remains the practical choice regardless of your baseline.

Current temperature

Verified data shows current temperatures across London ranging from 42°F to 57°F depending on location and time of day, with the Met Office recording 7°C (approximately 45°F) in Greater London and 10°C (approximately 50°F) in the City of London as of the latest hourly readings. Overnight lows drop to around 42°F, while afternoon highs climb toward the upper 50s on milder days. The feels-like temperatures—5°C in Greater London and 9°C in the City of London—account for wind chill effects from the gentle but persistent breeze.

Feels-like factor

The difference between actual and feels-like temperatures illustrates why layering matters in London even when the thermometer reads favorably. The Met Office calculations show that in Greater London, a 7°C reading feels more like 5°C due to northeast winds, while the City of London’s 10°C registers as 9°C under a different wind direction. This 2-degree feels-like gap multiplied across a full day of exposure can make the difference between comfortable and chilled for anyone spending significant time outdoors.

What is the coldest month in London?

January typically holds London’s crown for the coldest month, though “coldest” in London terms means average lows hovering just above freezing rather than the severe temperatures found in continental Europe. The city’s maritime climate moderates extremes, preventing the bitter conditions seen in Berlin, Warsaw, or other capitals at similar latitudes.

Historical averages

London’s average January temperature sits around 3-4°C for overnight lows, with afternoon highs reaching approximately 7-8°C. This mildness compared to continental neighbors results from the Gulf Stream influence and the warming effect of the urban heat island—Greater London’s millions of inhabitants and dense infrastructure generate measurable heat that elevates temperatures above what a rural area at the same latitude would experience. Frost occurs regularly but rarely persists through daylight hours, and snow—once a novelty—has become increasingly sporadic over recent decades.

Winter extremes

The coldest recorded temperatures in Greater London history have dropped below -10°C during rare cold snaps, but these extreme events occur perhaps once every decade or longer. More typical winter lows range from -3°C to 2°C, with the variability increasing as climate patterns shift. The Met Office regional forecast data provides historical context for understanding these patterns, showing that current April conditions fall well above winter norms even during the cold start mornings the forecast describes.

What this means for you

London’s weather presents a paradox for travelers and residents alike: the city rarely experiences extremes, yet the constant variability catches people off guard. The verified data shows mild conditions likely to continue through the forecast period, with the Met Office’s 7-day point forecasts providing reliable guidance for the immediate future. However, anyone planning beyond a week faces increasing uncertainty—a limitation of even the most sophisticated weather modeling that no source can fully eliminate.

For visitors, the practical takeaway is straightforward: pack layers, check tomorrow’s forecast each evening, and don’t assume that a sunny morning means a clear afternoon. For those making longer-term decisions about events, travel, or outdoor activities, the 28-day national range mentioned in regional forecasts offers some orientation, though with diminishing confidence the further ahead you look.

The data underscores that relying on a single city-wide forecast for London invites disappointment—micro-regional differences of 3°C or more between neighborhoods can meaningfully affect comfort levels for anyone spending time outdoors.
