UK heatwave: Red extreme heat warning to take effect

June 24, 2026 - 13:09

A red extreme heat warning is set to take effect across parts of England and Wales starting at 09:00, with officials warning that the conditions could pose a risk to life. The alert, the highest level issued by the Met Office, signals that even healthy people may face serious health dangers, including heatstroke and exhaustion. Vulnerable groups, such as the elderly and those with pre-existing conditions, are urged to take extra precautions.

Temperatures are expected to climb above 35 degrees Celsius in some areas, with the possibility of breaking previous records. The warning covers a broad swath of central and southern England, as well as parts of eastern Wales. Local authorities have activated emergency plans, including setting up cooling centers and increasing patrols to check on rough sleepers. Transport services are also preparing for disruptions, as rail tracks risk buckling and roads may become damaged from the heat.

Health officials advise staying indoors during the hottest part of the day, keeping hydrated, and checking on neighbors. Schools in affected regions are considering early closures or adjusted schedules. The heatwave is forecast to peak over the next 48 hours before a cold front brings relief later in the week.
