A severe heat wave that swept through parts of Europe in late June 2026 resulted in at least 3,700 excess deaths, according to health authorities in France, Belgium, and the Netherlands. The heat wave, which lasted from June 20 to June 28, brought temperatures exceeding 40°C (104°F) and was described as the worst on record in Europe.
Death Toll Breakdown
France reported 2,025 excess deaths, marking a 29.1% increase compared to average figures, as stated by Health Minister Stephanie Rist. The majority of fatalities were among individuals over the age of 65, though there was also a notable rise in deaths among those aged 45 to 64. Public Health France indicated that mortality rates surged by over 90% during the peak of the heat wave, particularly affecting home and nursing home residents.
In Belgium, the Health Ministry recorded 1,222 additional deaths, representing a 39% increase in excess mortality, which officials termed unprecedented. The country experienced seven days of temperatures above 30°C (86°F) during the heat wave. The Netherlands reported around 480 excess deaths, primarily in the southern regions.
Government Response
As the death toll continues to rise, French Prime Minister Sebastien Lecornu faces a no-confidence vote in parliament regarding his government's response to the extreme heat conditions. The heat wave disrupted daily life, leading to school closures and the cancellation of various events, including a reenactment of the Battle of Waterloo in Belgium.

The rising death toll from the heat wave may prompt increased scrutiny on public health policies and disaster preparedness in European countries. This could affect sectors such as healthcare and insurance, as well as influence government spending on climate resilience initiatives.
