The UK is set to experience its fifth heatwave of 2026, with temperatures potentially reaching 39C in some areas. The Met Office has confirmed that heatwave conditions are likely to return next week, following a series of scorching spells earlier this year.
Heat alerts issued for seven regions
The UK Health Security Agency (UKHSA) has issued yellow heat health alerts for seven UK regions, effective from 9am on Saturday until 9pm on Tuesday, spanning 84 hours. Among these, London, the South East, South West, and East of England have been given a 'risk score' of 10, indicating the highest level of concern.
The UKHSA warns that significant impacts are possible across health and social care services due to the high temperatures, including a rise in deaths, particularly among those aged 65 and over or with health conditions. There may also be impacts on younger age groups.
Health services under pressure
The risk description also highlights a likely increase in demand for health services. Internal temperatures in care settings, such as hospitals and care homes, may exceed recommended thresholds for clinical risk assessment, potentially affecting the ability of the workforce to deliver services.
Other significant impacts include indoor environments overheating, increasing risks to vulnerable people living independently in community and care settings. Water-related incidents may also increase, including risks from cold-water shock and drowning.
Met Office guidance for staying cool
The Met Office advises staying cool indoors by closing curtains in rooms that face the sun, and shutting doors and windows during the hottest parts of the day. People are urged to drink plenty of fluids, avoid excess alcohol, and never leave anyone in a closed, parked vehicle, especially infants, young children, or animals.
The forecaster also recommends staying out of the sun between 11am and 3pm when UV rays are strongest. If going out, walk in the shade, apply sunscreen, and wear a wide-brimmed hat.
