With Western Europe in the grip of a punishing early-summer heat wave, maximum health alerts have been issued in Rome, Paris, and even London. Thursday was the UK’s and Switzerland’s hottest June day on record, with each just below 100 degrees F, while France endured its warmest day ever on Wednesday, with temperatures in some areas rising to approximately 111 degrees F.

The toll of the sweltering temperatures driven by a heat dome has been stark: French authorities have recorded at least 48 drownings as people try to escape the heat, while hot cars have tragically claimed the lives of three young children. Spain is seeing a similarly tragic reality.

Italy has recorded the highest heat mortality in Europe for three consecutive summers.

Italy, where I live, is under severe strain too. Even though this is the country that holds the title for Europe’s hottest-ever temperature (119.8 degrees F in Sicily in 2021), the current climate is testing those limits once again. On Friday, the Italian Ministry of Health placed 18 major cities on strict Level 3 red alert (bollino rosso), indicating immediate risk to even healthy adults. These cities include Rome, Milan, Florence, Venice, Turin, Bologna, Genoa, and Bari.

That warning seems prescient—of the five people who have died so far, one was a 61-year-old male in the Piacenza area who collapsed while working in his vineyard. Though this initial toll seems small compared to those in Spain and France, Italy has recorded the highest heat mortality in Europe for three consecutive summers, capturing a grim toll of roughly 18,800 deaths in 2022, 13,800 in 2023, and over 19,000 in 2024.
