During the summer of 2026, Western Europe experienced its hottest June, July, and August on record, leading to over 34,600 heat-related deaths across five countries. Spain recorded 5,805 excess deaths from May 15 to September 30, marking its deadliest summer since 2015, according to the Instituto de Salud Carlos III. Extreme temperatures also affected France, Germany, Britain, and Belgium, with Copernicus data showing that Western Europe saw heat above 30°C for at least 60% of days on 17 occasions in 2026 compared to just 11 such days during the extreme summer of 2003.

Story summary
During the summer of 2023, Western Europe experienced its hottest June, July, and August on record, leading to over 34,600 heat-related deaths across five countries: Spain, France, Germany, Britain, and Belgium. In Spain alone, there were 5,805 excess deaths due to extreme heat between May 15 and September 30, marking the deadliest summer since records began in 2015. The previous record was set in 2003 when tens of thousands of heat-related deaths occurred in Britain, France, and Germany, prompting authorities to enhance emergency responses and hot-weather services. This year’s unprecedented heat waves have raised concerns about the vulnerability of elderly populations and existing health conditions exacerbated by high temperatures.
