At least 40 drown as most intense June heatwave on record hits France
At least 40 people have drowned in France since June 18, 2026, while seeking relief from an exceptional heatwave that has pushed temperatures to record levels across much of the country.

France recorded its hottest night since national records began in 1947 during the night of June 22–23, according to Météo-France. The national temperature indicator, based on observations from 30 stations across the country, reached 21.6°C (70.9°F), surpassing the previous record of 21.4°C (70.5°F) set on July 25, 2019.
Speaking after a crisis meeting on June 23, Prime Minister Sebastien Lecornu said many of the drowning victims were young people who entered unsupervised swimming areas during the heatwave.
“They are the first victims of the crisis we are facing,” Lecornu said, describing the fatalities as a “tragic scourge.”
Sports Minister Marina Ferrari warned that swimming in unauthorized locations during extreme heat presents serious risks, as authorities continued to investigate dozens of recent drowning incidents reported across the country.
Additional heat-related fatalities were also reported. Local authorities in Carpentras, southeastern France, said the heatwave was the most likely cause of the deaths of two children, aged two and four, who were found unconscious in a vehicle outside their home. In the Bordeaux region, three people aged between 80 and 95 died from heat-related health complications, according to regional prefect Sophie Brocas.
The heatwave has coincided with temperatures rarely observed in France, even during the country’s most severe historical heatwaves. Météo-France described conditions as comparable to the August 2003 heatwave while noting that the current episode could exceed the 2003 event in maximum intensity. Uncertainty remains regarding its eventual duration. The August 2003 heatwave lasted 16 days.
The agency reported that national average temperatures reached exceptional levels on June 22, and warned that the country could experience some of its warmest days ever observed during the current week.
Forecasts called for temperatures of 40–42°C (104–107.6°F) across large parts of the country through at least June 26, with localized peaks reaching 43°C (109.4°F).
The night heat has been equally exceptional. During the night of June 21-22, temperatures remained at 27.9°C (82.2°F) in Montemboeuf, 26.4°C (79.5°F) in Château-d’Olonne, 24.8°C (76.6°F) in Tours, 24.6°C (76.3°F) in Poitiers, and 24.1°C (75.4°F) in Bourges. Météo-France said such nighttime temperatures reached levels never previously observed in several locations and warned that remarkably warm nights would expand across more than three-quarters of the country during the week.
Maximum temperatures also shattered records. On June 22, Météo-France recorded 43.3°C (109.9°F) in Châteaumeillant, 43.1°C (109.6°F) in Bélis, and 43°C (109.4°F) in both La Couronne and Pissos. By late afternoon, temperatures had reached unprecedented monthly levels in several cities, including 42°C (107.6°F) in Saintes, 41.9°C (107.4°F) in Bordeaux, 41.6°C (106.9°F) in Niort, and 41.2°C (106.2°F) in Poitiers.
The heat smashed temperature records in multiple cities, strained public services and increased pressure on infrastructure nationwide. Météo-France placed 54 departments under red heatwave alert, the highest level in the national warning system. Schools shortened schedules or closed early, while power networks operated under heightened demand during a period of sustained extreme temperatures. France remains less reliant on residential air conditioning than several other countries experiencing comparable heat.
Heat-related impacts extend beyond direct health effects. Météo-France warned that soil moisture deficits have intensified rapidly following a brief respite in May. As of June 22, soils in parts of Alsace, Aquitaine, Auvergne, Limousin and Midi-Pyrénées were approaching their driest levels since measurements began in 1959. The agency said conditions resembled those observed during major historical drought episodes and were expected to deteriorate further.
Forest fire danger has also increased sharply. Météo-France reported a growing number of vegetation and brush fires as prolonged heat, extremely dry conditions, low humidity and strengthening continental winds accelerated the drying of vegetation.
More than 20 departments were classified under high fire danger, with some forecast to reach red-level danger. The agency said this would be the first occurrence this year of the highest forest-fire danger classification and the first time such conditions would extend beyond southern France.
Similar extreme heat affected parts of Spain, the United Kingdom and other areas of western Europe. In the United Kingdom, the Met Office warned temperatures could exceed 39°C (102.2°F), threatening long-standing June records. Spain also faced exceptional heat, with temperatures approaching 40°C (104°F) in parts of the normally cooler north.
Meteorologists attributed the event to an Omega block pattern that has trapped a large dome of hot air over Europe while cooler air remained positioned on either side of the continent. The pattern has drawn hot air northward from North Africa and limited atmospheric mixing.
“It’s drawing warm air up from North Africa, from the Sahara, and that’s why we have this really intense heat,” said Clair Barnes, a research associate in extreme weather and climate at Imperial College London. “It’s very slow moving, and it means there’s kind of no wind, no breeze for respite.”
According to Météo-France, the current episode is the 52nd heatwave recorded in France since 1947. Two-thirds of all recorded French heatwaves have occurred since the beginning of the 21st century. The agency said half of all heatwaves recorded since 1947 occurred before 2010, while the other half occurred after 2010, within just 15 years.
