Today's weather at a glance

London is waking up to a glorious Bank Holiday Monday, with brilliant sunshine already warming the city from the early hours. The current temperature sits at a pleasant 17.7°C, but don't be fooled by the morning mildness — forecasters expect the mercury to surge dramatically through the afternoon, reaching a scorching peak of 33.6°C by mid-afternoon. That's well above the average May high for London of around 18°C, making this one of the hottest May Bank Holidays on record.

There is absolutely no rainfall forecast for the day. Londoners can enjoy wall-to-wall sunshine from sunrise through to sunset, with winds remaining light and humidity staying relatively comfortable in the morning before building as the day heats up.

Heat alert: With temperatures expected to exceed 33°C this afternoon, the UK Health Security Agency advises extra care — particularly for the elderly, young children, and those with underlying health conditions.

Today's UV index is forecast to reach Very High (7–8) during peak hours between 11am and 3pm. This level of UV radiation can cause sunburn on unprotected skin in as little as 15–20 minutes.

Enjoying London in the heat

If you're planning to make the most of the Bank Holiday sunshine, London has plenty of shaded and cool spots. Hyde Park, Regent's Park, and Victoria Park all offer large tree-lined areas perfect for a picnic in the shade. The South Bank has excellent river breeze throughout the day, and many of London's free museums — including the British Museum and the Natural History Museum — offer cool, air-conditioned respite during the hottest hours.

If you're heading into Zone 1, be aware that the London Underground will be significantly hotter than outside temperatures — some lines can exceed 40°C in carriages. Carry a water bottle and, if possible, opt for Overground or bus services on days like today.
