Forty people have drowned in unsupervised waters across France since mid-June, according to Prime Minister Sébastien Lecornu, as an intense, record-breaking heatwave grips much of Europe. Driven by a stagnant mass of hot air from the Sahara, the extreme temperatures have triggered red alerts across 54 French departments, forced the closure of over 1,300 schools, and prompted the UN Secretary-General António Guterres to warn that the climate crisis is pushing the planet toward “catastrophic tipping points.”

Why are drowning rates spiking during heatwaves?

Drowning incidents increase during heatwaves because more people seek relief in unsupervised or hazardous bodies of water, according to French officials. Prime Minister Lecornu described the trend as a “tragic scourge,” noting that most victims are young people. The danger is compounded by the “exceptional intensity” of the current heat, which has caused temperatures to climb toward 43 degrees Celsius in parts of western France, as reported by Météo-France. When individuals enter cold, natural water while overheated, they face a higher risk of physical shock and muscle cramps, which can lead to rapid exhaustion and drowning in areas lacking lifeguard supervision.

How does the current heatwave compare to historical records?

The intensity of the current heat event is unprecedented in modern record-keeping, which began in 1947, according to the national weather service Météo-France. While heatwaves are a recurring phenomenon, the current episode is characterized by its duration and the failure of temperatures to drop overnight. For instance, some weather stations in Spain reported overnight lows that stayed above 25 degrees, while Almería saw temperatures remain above 30 degrees for three consecutive nights. Climate scientist Clair Barnes of Imperial College London attributes this to a “bulging mass of hot air” that is slow-moving and lacks the breeze typically needed to provide respite from high daytime temperatures.

What are the primary risks to public infrastructure and safety?

Extreme heat poses immediate threats to both human health and critical infrastructure, according to regional officials. In the greater Paris region, Valérie Pécresse, the head of the Île-de-France, warned that rail networks cannot withstand temperatures exceeding 50 degrees, advising citizens to work from home to avoid transit disruptions. The heat is also linked to tragic domestic accidents; a prosecutor in Carpentras confirmed that two children, aged two and four, died after being found unconscious in a family car on Monday. Across Europe, the crisis has prompted widespread government intervention, with Italy issuing red alerts in 15 cities and the UK Met Office issuing its second-ever red heat warning.

Future trends: Preparing for more frequent extreme heat

Scientists and global leaders suggest that the frequency and intensity of heatwaves will likely increase as the climate warms, according to statements from the UN. The current energy crisis, which UN Secretary-General António Guterres described as a result of a world “hooked on hydrocarbons,” is being linked to the broader climate instability driving these events. As infrastructure—from schools to railway lines—faces pressure to adapt to these new temperature ceilings, urban planning will likely shift toward heat-resilient designs, such as increased tree canopy coverage and cooling centers, to mitigate the risks to vulnerable populations.

Frequently Asked Questions

• Why are schools closing in France and the UK? Schools are closing because classrooms often lack the necessary cooling infrastructure to remain safe when temperatures reach 40 degrees or higher.
• What is a “red heatwave alert”? A red alert is the highest level of warning issued by national meteorological services, indicating that the heat is “oppressive and exhausting” and poses a significant threat to the health of the general population.
• How can I stay safe during a heatwave? Experts recommend avoiding rail travel when possible, staying hydrated, working from home, and avoiding swimming in unsupervised natural water sources.
