Europe Heatwaves Cause Over 35,000 Deaths As Insurers Face Rising Claims

A series of intense, back-to-back heatwaves across Europe this summer caused at least 35,000 excess deaths and triggered a rise in drownings, according to provisional health data and rating agency reports released in late August 2026.

Official records from barely half the continent indicate that Germany, France, and Spain sustained the heaviest casualties, with extreme temperatures regularly exceeding 40 degrees Celsius. The figure is projected to rise significantly once full August mortality figures are consolidated.

Germany reported the highest casualties, logging approximately 14,000 heat-related deaths between April 6 and August 9. The Robert Koch Institute public health agency noted that 9,600 people died during a single peak week in late June. Meanwhile, Spain registered 4,947 heat-attributable deaths, making 2026 its deadliest year on record for extreme heat.

In France, public health authorities reported 7,300 all-cause excess deaths between late May and July 22. In addition, the country experienced 301 drownings starting June 19—a 14 percent increase compared to 2025—as citizens attempted to cool off in unmonitored waters and private pools.

"Tragic toll," said Marina Ferrari, Sports and Youth Minister.

The minister explained that many fatal accidents occurred in unauthorized swimming areas such as open canals. She added that elderly residents faced severe risks in individual pools due to temperature shock and physical overexertion.

"Many deadly accidents have occurred in areas that are not authorised or supervised for swimming," said Marina Ferrari, Sports and Youth Minister.

Ferrari emphasized that local authorities are working to improve safety across designated swimming zones.

"Open water, in canals for example," said Marina Ferrari, Sports and Youth Minister.

The minister noted that severe heat often prompts people to take uncalculated risks in natural bodies of water.

"To improve swimming areas and make things safer," said Marina Ferrari, Sports and Youth Minister.

She warned that plunge-induced cold shock remains a primary driver of sudden drownings during severe heat spikes.

"Many drownings, particularly among the elderly, occurred in individual pools," said Marina Ferrari, Sports and Youth Minister.

Ferrari reiterated that swimmers often underestimate environmental conditions when attempting to cool down.

"People can also exceed their physical capabilities," said Marina Ferrari, Sports and Youth Minister.

Beyond immediate public health crises, the prolonged extreme weather threatens broader economic sector stability. According to an assessment by rating agency S&P, insurance companies face diminished profits due to surging payouts linked to heat deaths, health complications, wildfires, and agricultural droughts.

S&P highlighted that an aging European demographic heightens vulnerability, as citizens aged 65 and over represented nearly 85 percent of excess deaths during peak heat surges. The rating agency warned that rising claims could eventually force insurers to raise customer premiums across the region.
