The UK is preparing for its hottest day ever as a red weather warning has been issued for Wednesday and Thursday amid a severe heatwave affecting southern England. Temperatures are expected to approach 40C, close to the national record of 40.3C set in July 2022.
Nearly 500 schools across the country are either closing early or cancelling trips to protect pupils from the extreme heat. Emergency services and transport operators have urged the public to exercise caution as the Met Office warns of widespread health risks and significant disruption.
More than 300 schools in counties including Somerset, Buckinghamshire, Gloucestershire, and Hampshire have announced partial or full-day closures over the coming days. Many schools have cited the absence of air conditioning and concerns about travelling in the heat as reasons for the closures. Pupils have been allowed to wear lighter PE kits instead of full uniforms, and some after-school activities have been cancelled. Entire schools such as Buckingham School and St John’s Marlborough are fully closed, with remote learning arrangements in place.
The British Army has also paused ceremonial duties in London and Windsor to protect soldiers, horses, and the public from heat-related risks. Iconic events like the Changing of the Guard at Buckingham Palace will be suspended from Tuesday until Thursday, and mounted units are adjusting routines to reduce stress on horses.
Transport disruption warnings have been issued by train operators including South Eastern Railway, Govia Thameslink Railway, and Chiltern Railways. These companies anticipate severe delays and reduced services due to heat-related infrastructure issues such as rail expansion and sagging overhead power lines. Network Rail and Transport for London advise passengers to travel only if absolutely necessary during the red warning period. Eurostar has also cancelled some cross-Channel services due to the adverse weather conditions.
Before the heatwave, violent thunderstorms swept across southern England, with over 29,000 lightning strikes recorded overnight. The storms caused power outages affecting hundreds of homes, flooding, and at least two house fires linked to lightning strikes. The London Fire Brigade responded to more than 400 calls, including emergencies related to flooding and fires.
The UK Health Security Agency has issued a red Heat Health Alert covering much of England and Wales, warning that the extreme heat poses a life-threatening risk even for healthy individuals. Experts have noted that Britain’s infrastructure is under significant strain, with the heatwave serving as a stress test for transport networks and buildings not designed to cope with such high temperatures. Elevated night-time temperatures are also causing discomfort and raising health concerns across the region.
