Hottest Day Ever Recorded in France as Europe Grapples with Devastating Heat Wave

France’s hottest day on record—29.8°C (85.6°F)—has forced the Louvre and Eiffel Tower to close early as a June heat wave grips Europe, disrupting schools, transport, and tourism. The record, set Tuesday, follows a pattern of extreme heat linked to climate change, with officials warning of life-threatening risks as temperatures near 40°C (104°F) in multiple countries.

France’s national thermal indicator reached 29.8°C (85.6°F), surpassing the previous record of 29.4°C (84.9°F) set in August 2003 and July 2019, according to Météo France. The agency forecast further record-breaking temperatures, including potential all-time highs, as the heat wave persists at least through the weekend. In Paris, roofer Gin Dujardin described working conditions as "impossible," comparing the heat to Dubai levels. Meanwhile, France has recorded 40 drowning deaths in the past week as people sought relief in rivers and lakes, despite warnings against unsupervised swimming.

Why is this heat wave so dangerous?

The heat wave has reached a "plateau of severity," with unrelenting temperatures day and night, Météo France said. By Wednesday, over half of France—including the northernmost regions—faced red alerts, signaling extreme risk. The lack of widespread air conditioning in buildings and public spaces exacerbates the threat, particularly for vulnerable groups like the elderly.

In 2003, a similar heat wave killed an estimated 15,000 people, many in poorly ventilated apartments. This year’s early onset has already drawn comparisons, with officials warning of preventable deaths if precautions aren’t taken. The World Health Organization’s Europe office reported that over 200,000 heat-related deaths occurred across the continent in the past four years—most of them avoidable.

How are businesses and institutions responding?

Tourism hotspots like the Louvre Museum and Eiffel Tower have adjusted operations to mitigate risks. The Louvre will close two hours earlier from Wednesday to Saturday, citing "heat buildup" intensified by high visitor numbers. The Eiffel Tower, which typically stays open until late, will close in the afternoon. Both institutions acknowledged their buildings are "not sufficiently adapted to climate change."

Transportation networks are also under strain. In the UK, hundreds of schools closed or shortened hours, while train operators canceled or reduced services to prevent heat-related rail disruptions. The Met Office issued heat warnings for Wednesday and Thursday, with London and southern England expected to reach 39°C (102.2°F)—potentially breaking June’s all-time record.

Spain’s Aemet weather service issued red alerts for temperatures nearing 44°C (111°F) in southern Andalusia, while northern regions like Cantabria and the Basque Country faced warnings of 40°C (104°F)—unusual for their temperate climate. Meteorologist Rubén del Campo noted that Spain’s heat waves are becoming more frequent, longer, and earlier, directly tied to climate change.

What does this mean for Europe’s future?

Europe is warming twice as fast as the global average since the 1980s, according to the European Union’s Copernicus Climate Change Service. The continent experienced its second-highest number of "heat stress" days in 2024, with 2024 declared the hottest year on record worldwide. Scientists warn that climate change is worsening both the frequency and intensity of heat waves, particularly in southeastern Europe, increasing risks of wildfires and heat-related illnesses.

The UN’s climate agency projects that the next five years will likely see more heat records shattered. With Europe’s infrastructure—from schools to rail networks—ill-equipped for extreme heat, officials are urging preparedness measures. Meanwhile, businesses and cultural institutions are being forced to adapt, highlighting the economic and operational costs of a warming planet.
