Paris and 16 French departments hit by unprecedented May heatwave: 39C forecast
Paris and 16 other French departments brace for unprecedented May heatwave as temperatures hit 39°C
France’s national weather agency, Météo-France, has placed Paris and 16 other departments under orange heatwave alert from midday Thursday, warning of temperatures peaking at 39°C—levels never before recorded in May. The heatwave, driven by a Saharan heat dome, will persist through the weekend, shattering records for both intensity and earliness, with climatologists calling it a "silent killer" responsible for more deaths than floods.
SNCF cancels trains amid fears of air-conditioning failures, suspending services on key routes including Paris-Southwest and Bordeaux-Marseille until Saturday. The rail operator cited risks of overheating infrastructure and passenger safety, as older trains struggle with extreme temperatures. Officials confirmed the cancellations would affect Thursday and Friday, with normal service resuming only after the heat subsides .
Health risks escalate as heatwave arrives early Robert Vautard, co-chair of the IPCC, warned that France remains ill-prepared for increasingly frequent early-season heatwaves, which disproportionately endanger elderly, homeless, and outdoor workers. With 14 heat-related deaths already reported across Europe—including in France, Germany, and the UK—authorities are scrambling to activate cooling centers and distribute water in high-risk areas. Schools in Paris may adjust schedules, though no official closures have been announced .
Climate crisis accelerates as Europe warms twice as fast as global average A Copernicus report released Wednesday confirmed Europe is the fastest-warming continent, with temperatures rising at double the global rate. The current heatwave, stretching from Ireland to Italy, has already forced red alerts in Italian cities including Bologna, Florence, Rome, and Turin, where authorities expect 40°C+ by Friday. Scientists link the extreme conditions to climate change, noting that human cooling mechanisms—like sweating—may soon prove insufficient in such heat .
Political fallout grows as energy transition debates resurface The heatwave has reignited criticism of France’s delayed climate policies, with experts arguing that electrification and renewable energy could mitigate future crises. The crisis arrives just months after energy price protests led to rollbacks in green regulations, leaving cities like Paris vulnerable to blackouts if demand for cooling spikes. Meanwhile, Météo-France attributes the heat dome to atmospheric blocking patterns, a phenomenon becoming more frequent due to Arctic warming .
Background: A new normal? France’s last May heatwave occurred in 2022, but this year’s event is earlier and more severe, with temperatures 10-15°C above seasonal norms. Climatologists predict such episodes will become annual occurrences by 2050 without drastic emissions cuts. For now, Paris and other cities are activating emergency plans, but officials warn that long-term adaptation—from heat-resistant infrastructure to urban greening—remains critically underfunded.
