A rare red weather warning has been issued for large parts of England and Wales as temperatures are predicted to reach 40C later this week. The Met Office alert spans from Wednesday morning through Thursday night, covering London, the Midlands, southern England, and south-east Wales. Forecasters anticipate the combination of high humidity and extreme heat will likely cause significant disruption to daily life, travel, and public services.
The UK Health Security Agency (UKHSA) has mirrored this with its own red heat health warnings, advising that the conditions pose a serious risk to life and will impact public health across the population. While temperatures are expected to climb early this week, the peak of the heatwave is projected for Wednesday and Thursday, potentially approaching the UK’s all-time record of 40.3C.
In response to the extreme forecast, many schools are planning early closures or relaxing dress codes. Meanwhile, the National Fire Chiefs Council has urged caution regarding the rapid spread of wildfires and water safety. Infrastructure services are also taking precautions; water companies are requesting restricted usage, while the AA and RAC have warned of potential road surface damage and vehicle breakdowns. Railway operators have already reported delays, with further network-wide disruptions expected as the heat intensifies.
