France, Belgium, and the Netherlands have recorded at least 3,700 excess deaths during a severe heatwave that gripped Europe in late June, with authorities cautioning that these initial figures are preliminary and likely to rise. The intense heat, which persisted from approximately June 20-28, is being described by experts as the worst recorded in Europe, leading to widespread disruption, including strain on power generation, damage to infrastructure, and overwhelmed healthcare systems.

Scientists have indicated that the extreme temperatures were almost certainly exacerbated by climate change.

In France, Health Minister Stephanie Rist reported 2,025 excess deaths during the heatwave, with a notable increase in fatalities among individuals over the age of 45. Data from the country's public health authority indicated a 91 percent rise in deaths occurring at home between June 22-28 compared to the previous week. Deaths in nursing homes and healthcare facilities also saw an increase. The authority warned that the final mortality figures would likely exceed these preliminary assessments.

Belgium's Health Ministry registered approximately 1,200 excess deaths between June 18 and June 29. Of these, 530 were among individuals aged 85 or older, while 180 were recorded in the under-65 age group. The ministry stated that such a level of excess mortality during a heatwave is unprecedented in the country. A woman cools off under a mist sprayer.
