The UK heatwave is expected to last longer than initially forecast, with temperatures climbing into the mid-30s Celsius this week. The Met Office has updated its outlook, indicating that the prolonged spell of hot weather could be one of the longest since 1976.
Temperatures to Peak on Thursday and Friday
Thursday and Friday are forecast to bring the hottest conditions, with some areas potentially reaching 35C to 36C. High pressure is keeping skies clear, conditions dry, and sunshine widespread across the country.
The UK Health Security Agency (UKHSA) has issued amber and yellow heat health alerts, warning of significant impacts likely across health and social care services due to the high temperatures.
Prolonged Heatwave Continues into Next Week
According to the Met Office, the very warm weather will persist into next week. Deputy Chief Forecaster Tom Crabtree said: “Many people will understandably want to know how long the current heatwave is likely to last. While temperatures are expected to ease across southeast England through the weekend and into next week, it won't be a straightforward end to the warm weather.”
Crabtree added: “High pressure is expected to remain in charge through much of next week, but it will gradually migrate northwards. This means that an easterly wind will become established in the south, and the focus for the hottest conditions will migrate towards the southwest.”
Regional Temperature Forecast
The southwest of England will see the highest temperatures over the weekend, with 34C expected on Saturday and around 33C on Sunday before a slow decline begins. Scotland and Northern Ireland will also experience unusually warm conditions, with temperatures possibly reaching 27C to 28C on Friday and staying in the mid-20s Celsius over the weekend.
Although the current spell is expected to be less humid than the late June heatwave, some areas may still struggle with warm nights. Towns and cities could experience higher overnight temperatures, making it uncomfortable for some people to sleep, the Met Office said.
Wildfire Risk and Safety Advice
A National Fire Chiefs Council (NFCC) spokesperson urged caution: “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.”
“We’re asking everyone to take extra care outdoors, whether that’s avoiding disposable barbecues in the countryside, parks or moorlands, or making sure cigarettes are fully extinguished. A few simple actions can make a huge difference and help prevent fires before they start,” the spokesperson added.
