Met Office Chief Meteorologist, Matthew Lenhert, said: “Sunday will be another hot day quite widely across the southern half of the UK, with temperatures forecast to reach 31°C in the south east of England. Temperatures will be higher still on Monday, with highs of 34°C possible in central and eastern parts of England. This coincides with the end of Glastonbury with lots of people traveling home, and the start of Wimbledon so people should be prepared for some hot and humid conditions. Stay hydrated and try to keep out of the sun during the hottest part of the day.

“Overnight temperatures will remain high, with some locations not dropping below 20°C in what is called a tropical night. These sorts of temperatures make it hard to sleep and prevent any recovery from the high daytime temperatures too. Tuesday will be another hot day, though the highest temperatures will be more confined to the south east of England where 35°C is possible. Fresher air will move in from the west through the middle of the week, bringing an end to this heatwave.

“It won’t be hot everywhere, with a marked difference in northwestern parts of the UK. Cloud and some heavy rain will affect Northern Ireland and western parts of Scotland through Monday and temperatures will be suppressed to the mid to high teens.”
