Temperatures could hit 40C in UK as rare red heat warning issued

The United Kingdom is bracing for unprecedented heat as the Met Office issues a rare red warning for extreme temperatures across parts of England and Wales. The warning, active from Wednesday morning through Thursday evening, forecasts highs potentially reaching 40 degrees Celsius (104 degrees Fahrenheit) in affected areas, including London, the Midlands, and southern England.

This extreme heat, exacerbated by high humidity, is predicted to cause significant disruption. Forecasters warn of potential travel chaos and impacts on public services. Some schools have already announced early closures, and authorities are urging the public to be prepared for the severe conditions. The Met Office highlighted that such heat poses a serious risk to health, potentially leading to illness and danger to life.

Less severe amber warnings are also in place for wider areas of southern and central England and most of Wales from Monday. The anticipated peak temperatures on Wednesday and Thursday could rival the UK's all-time record of 40.3C, set in July 2022, the only previous occasion a red heat warning was issued. Some areas may experience 'tropical nights,' with temperatures failing to drop below 21-22C.

The UK Health Security Agency (UKHSA) has also issued its own red heat health warnings, urging health and social care services to prepare. Dr. Agostinho Sousa emphasized the vital importance of public awareness regarding the risks of high temperatures and the need for individuals to ensure their safety and that of their communities. As temperatures began to climb, some initial disruptions were already being observed, with schools implementing measures like relaxed uniform policies and early dismissals.

It is vitally important that people understand the risk posed by high temperatures like these, and take steps to keep themselves and their friends, families and neighbours safe.
