France recorded more than 5,700 excess deaths during a June heatwave, the country's health authorities have confirmed, highlighting the deadly impact of extreme temperatures exacerbated by climate change.
Excess deaths spike during extreme heat
Santé Publique France, the national public health agency, reported that between June 18 and June 24, 2026, there were 5,734 more deaths than the average for that period in previous years. The figure represents a 23% increase in mortality compared to the baseline.
According to the agency, the heatwave was particularly severe in southern and central regions, with temperatures exceeding 40°C (104°F) in some areas. The elderly and those with pre-existing health conditions were most affected.
Government response and warnings
French Health Minister Brigitte Bourguignon said the government had activated its heatwave plan, which includes opening cooling centers, issuing public health alerts, and checking on vulnerable individuals. “We are facing an unprecedented situation that requires vigilance and solidarity,” Bourguignon said in a statement.
The heatwave also strained hospital emergency services, with a 15% increase in heat-related visits. Officials urged residents to stay hydrated, avoid outdoor activities during peak heat, and check on neighbors.
Long-term implications
Climate scientists warn that such heatwaves will become more frequent and intense due to global warming. France experienced three major heatwaves in 2025, and the 2026 event is already among the deadliest on record. The June heatwave follows a record-warm spring across Europe.
Environmental groups have called for accelerated climate action, including reducing greenhouse gas emissions and improving urban planning to mitigate heat island effects. The French government has pledged to achieve carbon neutrality by 2050, but critics say current measures are insufficient.
