Reports from public health and media outlets say a major heatwave in Europe leads to at least 3,700 excess deaths across France, Belgium and the Netherlands. The heatwave runs roughly from June 20 to June 28, described as the worst on record in Europe by at least one outlet. In France, the countries’ public health authority reports that deaths at home rise by 91% between June 22 and June 28 compared with the previous week. The increase also extends to deaths occurring in nursing homes and healthcare facilities, indicating wider pressure on health and social care systems during the extreme temperatures.

Other reporting characterizes the event as causing additional strain beyond mortality statistics, including disruption to power generation and damage to infrastructure, as well as overwhelming healthcare capacity. While the outlets emphasize different angles—public health reporting on the distribution of deaths versus broader impacts described by other sources—they all point to the same core finding: the heatwave corresponds with a substantial rise in mortality, summarized as at least 3,700 excess deaths across the three countries.
