The UK is bracing for potentially record-breaking temperatures as a red extreme heat warning expands to cover parts of Sussex and Surrey. Temperatures are forecast to soar above 40°C in some areas, mirroring the conditions that led to the previous highest recorded temperature of 38.7°C in Cambridge in July 2019.
The Met Office has intensified its warning, covering a larger swathe of England under the highest level of heat alert. This indicates a substantial risk to life and widespread disruption across multiple sectors, including road and rail networks, which are expected to face significant challenges due to heat-related issues such as track buckling and road surface melting.
A broader amber extreme heat warning remains in place for much of England, covering areas from London and the South East to the Midlands, North West, North East, and Yorkshire & the Humber. Temperatures are expected to exceed 35°C in these regions, posing significant health risks, especially for vulnerable populations such as the elderly, young children, and those with underlying health conditions.
Health authorities and emergency services have issued urgent advice, urging people to stay hydrated, seek shade during the hottest parts of the day (11 am to 4 pm), and avoid strenuous physical activity. There is a heightened risk of heat-related illnesses such as heatstroke and heat exhaustion, and individuals are advised to be aware of symptoms and seek medical attention if necessary.
As temperatures are expected to remain high throughout Monday and Tuesday, practical safety advice includes keeping homes cool by closing curtains and windows during the day, wearing loose, light-coloured clothing, and checking on vulnerable neighbours, friends, and family. The Met Office has also warned of increased risks of wildfires due to exceptionally dry conditions, urging caution with barbecues and discarded cigarettes.
