Met Office forecasts isolated thunderstorms but little relief from heat
The Met Office has issued its verdict on whether rain and thunderstorms will bring relief from the UK's third heatwave of 2026. Temperatures are forecast to peak at between 30C and 32C across parts of England and Wales as the scorching hot weather continues.
Deputy Chief Forecaster Steven Keates said: "The overall pattern continues to remain settled with large amounts of sunshine though this week, and temperatures peaking around 30C–32C across parts of England and Wales. In terms of rain, there's a chance of some showers and thunderstorms in isolated spots in the south of England on Wednesday and Thursday, but these are likely to be sporadic in nature, and many people won't see any rain this week."
Eastern coastal areas remain cooler
Eastern coastal areas are expected to remain cooler than inland parts of the UK this week, with onshore breezes and cloud helping to keep temperatures down. By the weekend, high pressure is expected to build back in from the northwest, reducing the risk of showers and bringing a return to more settled, dry and warm weather.
Temperatures are forecast to ease slightly by Saturday compared with the midweek peak, although conditions are still expected to remain fine and warm across many areas.
Wildfire and water safety warnings issued
The Met Office has also warned that the prolonged spell of hot, dry weather will continue to bring an increased risk of wildfires across parts of England and Wales, while breezier conditions in some southern areas could pose a danger for those heading onto the water.
A spokesperson for the National Fire Chiefs Council said: "When the weather stays hot and dry, it only takes one spark to start a wildfire. What can begin as a small fire can spread incredibly quickly, putting people, homes, wildlife and our countryside at risk."
Meanwhile, Lee Pooley, Head of Safety at Paddle UK, urged people to check the weather and wind direction before going out, warning that offshore winds can quickly carry paddleboarders and other water users away from the shore. He said winds blowing away from the coast can sweep people out to sea faster than they are able to paddle back.
The Met Office is also urging anyone planning to head onto the water to check the forecast before setting off.
