If you’ve been watching the clouds roll over the Thames and wondering whether tomorrow deserves a jacket or sunglasses, you’re in the right place.

What is London’s weather like tomorrow?

Wednesday April 22 is shaping up to be the clearest day London has seen in a while. According to the Met Office (UK’s national weather authority), any patchy fog will burn off quickly, leaving a fine day with plenty of sunshine. The forecast high of 17°C makes tomorrow noticeably warmer than today’s expected 14°C maximum.

Hourly forecast

Early risers should bundle up — AccuWeather records temperatures around 6°C at 6AM, feeling closer to 4°C with an 88% humidity reading. By 9AM, the mercury climbs to 9°C under intermittent clouds, with precipitation chances staying near zero. The afternoon should deliver the best of the sunshine, with temperatures peaking around 17°C by early afternoon.

Daytime conditions

Conditions look dry across all of Greater London. The Met Office’s Crystal Palace monitoring point shows only a 20% rain chance in the immediate next hour — and that likelihood drops further as the day progresses. London’s City Airport zone shows rain probability below 5% right now, with wind gusts of 24mph from the northeast making it feel cooler than the actual temperature.

Night outlook

Londoners can expect a chilly night once the sun sets. The Met Office notes isolated frost is possible, particularly in sheltered spots where winds ease off. Low cloud and patchy fog are likely to develop overnight, so those with morning plans should check visibility before setting out early Thursday.

What is the maximum temperature in London tomorrow?

The Met Office confirms a maximum temperature of 17°C for London on Wednesday, 22 April 2026. This figure holds across multiple monitoring points: central London, London City Airport, and the broader South East England region all show the same peak. Compare that to Tuesday’s expected maximum of 14°C — a meaningful 3-degree jump that will feel noticeably warmer under sunny skies.

Daytime highs

The 17°C reading is consistent across three independent Met Office sources: the regional South East England forecast, the Greater London city forecast, and the London City Airport point forecast. AccuWeather’s hourly model aligns closely, showing 13°C by 1PM, with a RealFeel of 51°F (11°C) accounting for the easterly breeze.

Overnight lows

The picture flips once the sun sets. Overnight into Wednesday, temperatures dropped to around 5°C for London and South East England, with the City Airport point recording a minimum of 6°C. Sheltered urban areas will stay slightly warmer, but open spaces — particularly parks and riverside areas — could see frost by early morning.

Comparison to today

Tuesday’s maximum of 14°C (per the Met Office London forecast) sits well below Wednesday’s 17°C. This 3-degree improvement reflects the shift away from Atlantic cloud cover and the arrival of drier, sunnier conditions. Stansted Airport to the north-east is tracking slightly warmer today at 15°C, with Wednesday expected to match or exceed that.

Will it be warm in London tomorrow?

Yes — by London April standards, 17°C qualifies as a genuinely warm day. The Met Office South East England forecast describes Wednesday as “fine with plenty of sunshine,” and the temperature sits comfortably above the seasonal average for late April in the capital. For visitors from cooler climates, this is T-shirt weather in the sunshine; for Londoners accustomed to the city’s fickle spring, it’s a day worth planning around.

Temperature trends

The week shows a clear warming trend. Tuesday brought 14°C with scattered showers and patchy cloud across the UK national forecast. Wednesday’s 17°C represents a three-degree gain, and the extended outlook through Saturday promises “mainly fine and dry” conditions, with the main caveat being low cloud and patchy fog developing overnight as easterly winds persist.

Feels-like conditions

The easterly breeze complicates the warmth picture. Met Office data shows gusts reaching 21–24mph at central and eastern London monitoring points, making the “feels like” temperature sit 3–4°C below the actual reading in exposed spots. Kingston Upon Thames in southwest London recorded gusts of 29mph, which would make 14°C feel closer to 10°C in an unsheltered location.

Clothing tips

Light layers work best. A base layer with a mid-weight jacket you can tie around your waist is the London spring sweet spot — warm enough for the sunshine, practical enough when the breeze picks up or cloud rolls through. Avoid heavy coats; the 17°C actual temperature rules those out, but don’t leave the jacket behind entirely since the wind will catch you off-guard in open areas.

Will recent storms affect London tomorrow?

No major storm systems are on course to hit London tomorrow. The Met Office’s regional forecast shows London’s weather settling after a series of Atlantic disturbances moved through this week. While exact storm names mentioned in search queries — Storm Benjamin, Storm Amy, Storm Melissa, Storm Dave — appear in broader UK weather coverage, none are forecast to impact the capital on Wednesday, 22 April.

Storm Benjamin update

The most recent Atlantic low-pressure systems have been tracking north and west of the UK, pulling away from the London area. The Met Office regional summary makes no mention of active storm warnings for the South East, and the forecast language — “fine,” “plenty of sunshine,” “dry” — indicates settled conditions, not post-storm cleanup.

Storm Amy and others

Based on available Met Office data, the storm systems referenced in common search queries appear to have passed through earlier in the week. Tuesday’s national forecast describes “scattered showers fading, sunny spells, breezy” — the language of a system exiting, not entering. No active warnings or alerts for the London region appear in the current forecast output.

Current paths

The UK national forecast shows low pressure clearing eastward, with high pressure building from the Atlantic. This pattern supports dry, sunny conditions for London and the South East through at least Thursday into Saturday. The easterly breeze mentioned in the outlook is a consequence of this high-pressure setup, not a storm remnant.

The trade-off: that easterly breeze that keeps things dry also suppresses temperatures in shaded areas. London isn’t facing storm damage or travel disruptions tomorrow, but anyone planning outdoor activities should factor in the wind chill, particularly in exposed locations.

How should you dress for London weather tomorrow?

Wednesday’s 17°C and sunshine call for a light, adaptable wardrobe — but not quite summer attire. The easterly breeze and residual overnight chill mean layers are still the sensible play for late April in London.

Layering advice

Start with a breathable base — a cotton T-shirt or thin long-sleeve works well. Add a mid-layer you can remove by midday: a Merino sweater, a cotton hoodie, or a light fleece. The key is easy removal; temperatures will feel different at 7AM versus 2PM, and the breeze makes a big difference between sunny and shaded spots.

For visitors

American travelers accustomed to April in New York or Chicago will find London’s 17°C more temperate — London sits milder in spring thanks to its maritime climate. Pack layers rather than heavy jackets. A waterproof jacket is smart; the city can produce surprise drizzle even when the forecast looks dry. Walking shoes with good grip are essential — London’s streets get slippery after light rain, and the puddles from recent Atlantic systems may linger in spots.

Wind considerations

The northeast breeze at 21–29mph (per Met Office monitoring points) will cut through light layers. Wind-exposed routes — the South Bank, Tower Bridge approaches, Hyde Park’s open areas — will feel noticeably cooler than the official 17°C. A jacket with a wind-resistant outer layer is more valuable than a thick insulated coat.

For tourists planning outdoor sightseeing: schedule your heaviest activity — the London Eye, walking the Thames path, visiting the parks — between 11AM and 3PM when the sun is strongest. Save museum visits or indoor attractions for the windier mid-afternoon hours.
