A sizzling heatwave is set to scorch the UK this week, with forecasters predicting temperatures could reach a sweltering 40C in some areas - just shy of the record high of 40.3C set in Coningsby last July. A rare red weather warning for extreme heat has been issued across parts of England and Wales, with temperatures expected to soar rapidly from Tuesday onwards.
The Met Office warning, which signifies a significant risk to life, will be in place from 09:00 BST on Wednesday until 21:00 BST on Thursday, covering London, parts of the Midlands, south-east Wales, and southern England. Temperatures are forecast to climb to at least 39C by Wednesday and Thursday, with some areas possibly reaching 40C.
The extreme heat poses a serious risk to public health, prompting the UK Health Security Agency (UKHSA) to issue its own red heat health warning. The agency has warned of widespread disruption to daily life, including travel networks, with schools already announcing plans to close early or entirely on Wednesday and Thursday.
Dr Agostinho Sousa, head of extreme events and health protection at UKHSA, has urged the public to take measures to stay safe during the heatwave. He stressed that health and social care services must be prepared for a potential surge in heat-related illnesses and deaths. The National Fire Chiefs Council (NFCC) has also called for increased vigilance around open water and outdoor spaces to prevent water-related incidents and wildfires.
Less severe amber weather warnings are also in effect across much of southern and central England and most of Wales from Monday through to the end of Thursday, signifying a high probability of heat-related health impacts. Water companies are already experiencing pressure on their networks, with some asking for essential-only water usage during the crisis.
As temperatures begin to climb, residents in affected areas are advised to stay informed and take proactive steps to mitigate the risks associated with this severe heatwave. With tropical nights expected, temperatures may not fall below 21C or 22C, exacerbating the already critical situation.
The Met Office has warned that the extreme heat could bring significant disruption to daily life, including travel networks, which are already experiencing strain as the country prepares for the worst of the heatwave. The UK is bracing itself for potentially its hottest temperatures on record in the coming days, with residents urged to take precautions and stay safe.
