The UK is bracing itself for potentially record-breaking temperatures as a severe European heatwave intensifies. A red weather warning has been issued by the Met Office for extreme heat across swathes of England and Wales, with forecasters predicting some areas could see mercury soar to 40C, particularly in London and the south-east.
Experts attribute this phenomenon to specific atmospheric patterns that trap hot air, leading to a gradual and sustained temperature increase. Global heating is also exacerbating these conditions, making intense heatwaves more frequent and severe. On Tuesday, Wisley, Surrey, recorded a high of 34.6C, but predictions for Wednesday and Thursday indicate a significant escalation.
Across Europe, the impact is already being felt. Italy's health ministry has declared a red alert for 16 cities, including Milan and Rome, while France has experienced its hottest day on record recently, with temperatures expected to reach 39C-41C from Brittany to Paris and much of the south-west.
Forty people have tragically drowned in unsupervised swimming areas across France in recent days. The Netherlands is also under a 'code orange' for extreme heat in its central and southern regions until at least Friday, with measures including free outdoor pool access and reduced train services.
The heatwave is expected to extend into Eastern Europe, with Poland, Croatia, and Hungary issuing high-level warnings and preparing for potentially record-breaking temperatures. In the UK, Grahame Madge from the Met Office stated that 39C remains the headline maximum forecast, but temperatures could exceed this if conditions align at the upper end of their predictive range.
London Mayor Sadiq Khan has activated a 'high' air pollution alert for the capital, while ceremonial military operations have been cancelled to protect soldiers and horses. Practical advice for the public includes staying hydrated, avoiding non-essential travel during peak heat hours, and checking on vulnerable friends and neighbours.
Schools in some areas are expected to close, and employers are being urged to consider flexible working arrangements due to the prolonged nature of this heatwave and high humidity, which poses significant health risks for the elderly, young children, and those with underlying conditions.
