Europe sizzles under 'heat dome' as France logs hottest May day on record

Europe experienced record-breaking May temperatures in 2026, with France and the UK logging their hottest May days ever, driven by a 'heat dome' trapping warm African air. Scientists link the extreme heat to human-driven climate change, warning of more frequent and severe heatwaves while countries like Italy imposed outdoor work restrictions and Spain forecasted peaks near 38C.
Europe is enduring an unprecedented early-season heatwave, with France recording its hottest May day on record on Monday. Météo-France reported temperatures soared beyond seasonal norms, while the UK’s Met Office confirmed its hottest May day at 34.8C in London’s Kew Gardens, exceeding previous records by 2 degrees. A high-pressure system, or 'heat dome,' pushed warm air from northern Africa over western Europe, trapping heat that meteorologists warn will persist until at least the end of the week. Spain is expected to reach 38C later in the week, while Italy restricted outdoor labor in affected regions. France’s beaches saw early-season crowds, and farmers reported accelerated harvests as temperatures surpassed 30C across the continent. Ireland also recorded a May high of 28.8C at two weather stations, while Scotland faced a grass fire near Edinburgh amid 25C temperatures. Scientists attribute the extreme heat to human-induced climate change, emphasizing that Europe is warming faster than the global average. The UK’s Met Office described the heat as 'exceptional even for midsummer,' while climate advisers warned the country’s infrastructure is unprepared for a rapidly changing climate. In 2022, the UK saw temperatures above 40C for the first time on record. The heatwave follows broader climate trends, with experts warning of more intense heatwaves, droughts, and floods. Greg Dewhurst of the Met Office called the rising temperatures 'a clear sign of climate change in action,' suggesting such extremes may become the new norm. Meanwhile, authorities urge adaptation measures for schools, hospitals, and other critical infrastructure to cope with worsening conditions.
