London Heatwave 2026: When Will the Scorching Heat End? Forecast
London Heatwave 2026: When Will the Scorching Heat End?

London at 30C is not dissimilar to a white-hot furnace. This week has been especially sweltering, with Tuesday breaking the record for the hottest May day ever in London, reaching 35.1C in Kew Gardens. Sure, a few days of blazing sun can be glorious, but after a couple of nights of dodgy sleep, laying under a damp sheet with a fan blasting in our faces, we are ready for this hot spell to ebb at least a little. So when can we expect the heatwave to wane? Well, you will be happy to hear there is an end in sight. At time of writing, the Met Office is predicting temperatures to reach highs of 29C on Saturday before dropping to 22C on Sunday. Finally, some breezy relief! There is even a 30 percent chance of rain at 11am on Sunday morning, which could really cool things down. On Monday things get even wetter. The Met Office predicts highs of 21C with a high chance of rain from midday into the evening. It will still be worth slapping on some sun cream, though, because the UV is expected to be moderate despite the cloud cover.

Saturday will see temperatures rise again, reaching 29C by 3pm. However, it will be windier than the previous day, with gusts up to 20mph, which will hopefully make the heat more manageable.
