A Gloriously Warm Friday Dawns Over London

Clear skies, a high of 27°C, and a touch of summer magic — here's everything you need to know before stepping outside today.

Clear Conditions
27°C Day High
10% Rain Chance
14°C Morning Low

London wakes to one of its finest Fridays of the year. A large area of high pressure has settled firmly over southern England, bringing with it wall-to-wall sunshine, crisp morning air, and afternoon temperatures that could rival some Mediterranean resorts. With a daytime high of 27°C (81°F) and only a 10% chance of any rainfall, today is the kind of day that makes Londoners genuinely grateful to live in this city.

The morning started cool — hovering around 14°C at sunrise — but thermometers are climbing quickly as the sun climbs above the rooftops. By mid-morning you can expect temperatures to reach the low 20s, and the mercury will peak in the mid-to-high 20s between 1pm and 4pm, making the afternoon the warmest part of the day. There is virtually no meaningful cloud cover forecast throughout the daylight hours, so expect intense, direct sunshine from dawn until dusk.

"Today is the kind of London day you wish you could bottle — bright, warm, and almost entirely rain-free."

A light south-westerly breeze of around 10–15 km/h will provide some welcome relief from the heat, particularly in open spaces like Hyde Park, Regent's Park, and along the Embankment. Humidity levels remain comfortably low, so the warmth should feel pleasant rather than sticky or oppressive. UV levels, however, are expected to reach High — a significant consideration for anyone spending extended time outdoors.

Thu 23°C  20%
Fri 27°C  10%
Sat 28°C  15%
Sun 31°C  10%
Mon 33°C  0%

The warm spell is set to intensify through the weekend, with Sunday and Monday threatening to push past 30°C. This could be one of London's most significant early summer heat events in recent years.

Precautions Before You Head Outside

With temperatures this high and UV levels elevated to 'High', a little preparation goes a long way. Here is what WeatherLondon.uk recommends before you step out the door.

Apply sunscreen

Use SPF 30 or above on all exposed skin, even on a 20-minute commute. UV index is forecast at 6–7 today — reapply every two hours if outdoors.

Stay hydrated

Carry a water bottle and aim to drink at least 2 litres throughout the day. Dehydration can sneak up quickly in heat like this, especially on the Underground.

Wear a hat & sunglasses

A wide-brimmed hat and UV-protective sunglasses will shield your face and eyes from prolonged exposure during the peak hours of 11am–3pm.

Choose light clothing

Opt for loose-fitting, light-coloured, breathable fabrics such as cotton or linen. Dark colours absorb more heat and will make an already warm commute uncomfortable.

Time your activities wisely

If you're exercising or doing strenuous outdoor activities, plan for early morning (before 10am) or early evening (after 6pm) to avoid peak heat and UV radiation.

Look out for vulnerable people

Elderly neighbours, young children, and those with heart or respiratory conditions are most at risk in heat. Check in on them and ensure they have access to shade and cool water.

The Best Spots to Enjoy the Sun in London Today

A day this fine practically demands you spend some of it outdoors. Hyde Park and Kensington Gardens offer vast lawns perfect for a picnic lunch. Primrose Hill provides sweeping skyline views and a cool breeze from the north. South Bank is at its vibrant best on a clear summer's day, with street performers, café terraces, and unobstructed views of the Thames glittering in the afternoon sun. For a quieter escape, Richmond Park offers shaded woodland walks and open meadows in equal measure.

If you're in the city for work, even a 20-minute lunchtime stroll through one of London's many squares — St James's Park, Grosvenor Square, or Lincoln's Inn Fields — will do wonders for the mood on such a splendid afternoon.
