The country is bracing itself for a sweltering week as the Met Office issues an unprecedented red weather warning for extreme heat across parts of the UK. From Wednesday morning onwards, large swathes of southern England, the Midlands, and southern Wales will be under severe threat, with temperatures potentially reaching record-breaking levels.
Forecasters predict that some areas could see temperatures soar above 40°C, a feat never before achieved in the UK, where the previous highest temperature was 38.7°C in Cambridge in July 2019. The heat is expected to have far-reaching impacts on daily life, affecting not only health but also transport and infrastructure.
The red warning zone covers primarily London and the South East, East of England, and parts of the Midlands in England, with southern Wales also included. While other regions are under amber warnings, they will still experience very warm conditions, particularly central and northern England.
The Met Office stresses that even healthy individuals face a substantial risk from extreme heat, which can lead to heatstroke, dehydration, and exacerbate existing health conditions. The high temperatures will put significant strain on public services, with potential widespread delays and cancellations across rail and road networks, as well as increased demand on emergency services.
In response to the severe forecast, the public is urged to take immediate precautions, staying indoors during the hottest parts of the day, keeping hydrated by drinking plenty of water, and avoiding strenuous physical activity. It's also crucial to check on vulnerable friends, family, and neighbours, particularly the elderly and those with pre-existing health conditions.
The extreme heat is driven by a plume of hot air from southern Europe being drawn northwards over the UK. While complex, such events are becoming more likely due to climate change, making them a growing concern for the future.
