The UK is about to experience its hottest temperatures ever recorded as a red extreme heat warning takes effect from Thursday. The Met Office has issued this critical alert for parts of England, which will see potentially 40C temperatures sweep across central, eastern, and south-eastern regions.
While the Daily Express reports '53 areas' under this red warning, the Met Office advises a geographically specific area – primarily covering major population centres in central, eastern, and south-eastern England. This includes areas previously subject to amber extreme heat warnings, which remain in effect for Monday to Thursday across a broader swathe of England and parts of Wales.
Forecasters predict temperatures will steadily climb from Monday and Tuesday, with many areas already seeing highs in the low to mid-30s Celsius. Thursday is expected to be the peak of this heatwave. Regions under the red warning could see temperatures reaching 39C or even 40C, while amber warning areas – including much of the Midlands, East Anglia, and parts of the South West – will experience exceptionally high temperatures often in the mid to high 30s Celsius.
Scotland will see temperatures well above average, possibly reaching the high 20s Celsius in southern and eastern areas. Wales, under an amber warning, could experience temperatures in the mid-30s Celsius, particularly in eastern regions. Northern Ireland is expected to be very warm, with temperatures potentially reaching the low to mid-20s Celsius. Light wind speeds across the UK will offer little relief from the intense heat.
The Met Office advises the public to take immediate precautions: stay hydrated by drinking plenty of water, avoid strenuous activity between 11 am and 3 pm, and stay in the shade. Special attention should be given to vulnerable individuals such as the elderly, young children, and those with pre-existing health conditions. Employers are urged to consider flexible working arrangements and ensure workplaces are cool.
Practical safety advice includes keeping curtains closed to keep rooms cool, never leaving people or animals in parked cars, and checking on neighbours who may be more susceptible to the heat. If you feel unwell, seek medical attention immediately.
