The mercury is set to soar to unprecedented levels in South West England as the Met Office issues a rare red extreme heat warning for parts of Devon and Cornwall. Temperatures could reach 35°C or more in localised areas, posing a significant threat not just to vulnerable individuals but to the general population.
The red warning signals a critical risk that requires substantial changes to daily routines, with potential impacts on health services, transport, and infrastructure. Roads may buckle under the heat, while rail services could face speed restrictions due to tracks warping. The Met Office has urged people to stay hydrated, seek shade during the hottest part of the day, and avoid strenuous activity.
Across England and Wales, amber extreme heat warnings remain in place, with temperatures expected to exceed 30°C comfortably. Scotland and Northern Ireland will experience warmer-than-average conditions, but not at the same extreme level as South West England. In Northern Ireland, temperatures may reach high 20s Celsius, while parts of Scotland could see similar highs.
The public is advised to take immediate precautions to mitigate the risks associated with the heat. This includes staying hydrated by drinking plenty of water, seeking shade during the hottest part of the day (typically between 11 am and 3 pm), and avoiding strenuous physical activity. Pet owners are reminded to ensure their animals have access to water and shade.
The National Health Service has issued guidance on coping with the heat, advising individuals to check on elderly relatives and neighbours, and to be aware of the signs of heatstroke – confusion, dizziness, and a high temperature. Emergency services are bracing for an increase in calls related to heat-related illnesses and urge people only to call 999 in genuine emergencies.
With light winds forecast across the UK, temperatures will feel even more oppressive, especially in urban areas where heat can be trapped. The Met Office is continuously monitoring the situation and advises people to stay updated with the latest forecasts and warnings.
