Britain is set to roast this weekend as another heatwave arrives, with temperatures expected to rocket to 35C due to a plume of hot air from Europe. Amber heat health alerts have been issued for the east, South East, and South West of England, as well as London, in place until 8pm on Tuesday. There is a 40% chance of smashing the highest ever temperature for June next week, which currently stands at 35.6C.
Unusual Heat for June
Met Office meteorologist Alex Deakin admitted the scorching conditions are "pretty unusual even for the middle part of June." Deputy chief forecaster Greg Wolverson added: "Temperatures will peak around the mid-thirties Celsius on Monday and Tuesday. The humidity will also mean this feels close, warmer and more uncomfortable for many. Tropical nights – where the temperature doesn’t drop below 20C – are also likely for some."
Thunderstorm Risk
There is a small risk of the heat sparking thunderstorms in the South East and East Anglia on Sunday, June 21. The mercury is set to reach 28C on Saturday, June 20, before rising to 32C in the south. It could rise further to 34C on Monday for some parts of the UK.
BBC weather presenter Sara Thornton said it's set to stay in the high 20s or low 30s throughout next week. She added: "The early signs are that the last weekend of June could be even hotter, with some forecast models showing temperatures of 35C as very hot air from Europe continues to push our way."
Water Safety Warning
Swimmers have been warned to be vigilant in open water, following 15 deaths across the UK during May's hot weather. Samantha Hughes, the national water safety partner at the RNLI, said: "If you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing. You may need to gently use your hands to help you stay afloat, and it’s ok if your legs sink – everyone floats differently."
Betting Odds
Ladbrokes has slashed odds that the hottest day of the year in the UK comes this weekend. The bookies cut odds in half from 5/1 to just 5/2 that the hottest day of the year in the UK occurs on Saturday or Sunday. Spokesman Alex Apati said: "Brits should strap in and strip off for a record-breaking weekend of 2026 sunshine, if the latest odds are anything to go by."
