The UK is bracing for its hottest day yet this week, with the Met Office extending its red warning for extreme heat across large parts of the country. A swathe of central and southern England, parts of Wales, and areas in the Midlands will remain under the warning throughout Friday, posing a significant risk to life.
Temperatures are expected to soar again, with many areas under the red warning forecast to reach highs above 35 degrees Celsius during the day. In some cases, temperatures could even approach 40 degrees Celsius, while overnight lows will offer little respite from the heat.
The red warning covers regions in England such as London and the South East, East of England, and parts of the Midlands, with Wales' eastern and central areas also under threat. Scotland and Northern Ireland are not directly affected by the red warning but are still experiencing warm conditions, with yellow warnings advising caution in some areas.
The prolonged heat poses a significant risk to public health, particularly for the elderly, young children, and those with pre-existing health conditions. The NHS has urged people to stay hydrated, seek shade, and avoid strenuous activity during the hottest parts of the day. Infrastructure may also face disruption due to the heat, with speed restrictions and cancellations possible.
The risk of wildfires remains high in dry areas, and water companies are closely monitoring demand for responsible usage. Emergency services are bracing for an increase in calls related to heat-related incidents. The public is advised to regularly check Met Office updates and follow local authority guidance.
Practical safety advice includes staying indoors where possible, especially between 11 am and 3 pm, wearing light, loose-fitting clothing, drinking plenty of water, and checking on vulnerable neighbours, friends, and family. Pets should also be kept cool and hydrated, and never left in hot vehicles. With little wind expected to provide relief from the heat, people are advised to take extra precautions.
