The UK is bracing for a prolonged heatwave, with temperatures set to soar to 36C in parts of southern England this week – the longest since 1976. Amber and yellow heat-health alerts have been issued across England as forecasters predict sweltering conditions will persist throughout the country.
Forecasters say that by Tuesday, the heatwave criteria were met more widely, with highs of 32.4C recorded in Teddington, Richmond upon Thames, and Frittenden, Kent. Experts suggest that many locations could see temperatures reach 34C or 35C in the coming days, with southern England expected to be the epicentre of the most intense heat.
The warmth is set to spread further north and west, impacting Northern Ireland and Scotland, where temperatures are expected to reach the high 20s Celsius by Friday. By week's end, an easterly wind will bring some cooling to eastern areas of the UK, shifting the focus of the most intense heat further west.
Unlike last month's heatwave, humidity levels this week are forecast to be more moderate – potentially making temperatures feel less oppressive. However, 'tropical nights' where temperatures do not fall below 20C remain a possibility, particularly within larger towns and cities later in the week.
The prolonged period of high temperatures has prompted warnings about potential impacts on health and social care services, including an anticipated rise in deaths among those aged 65 and over or individuals with pre-existing conditions. To stay safe, residents are advised to stay hydrated, seek shade during peak sun hours (11 am to 3 pm), wear light clothing, and check on vulnerable neighbours.
The UK Health Security Agency has placed the Midlands, eastern, and southern England under an amber heat-health alert until 21:00 BST on July 12, while northern England is under a yellow alert for the same period. The Met Office continues to provide updated forecasts, urging residents to stay informed about local conditions.
