Late‑June Heatwave Causes About 3,700 Excess Deaths in France, Belgium and the Netherlands

Overview

• National authorities reported a combined total of about 3,700 excess deaths linked to the late‑June heatwave, with France reporting roughly 2,025, Belgium about 1,200 and the Netherlands about 480.
• The excess deaths were concentrated among older people, with significant rises among those over 45 in France, 530 deaths among Belgians aged 85 or older, and Dutch excess deaths mainly among people over 80.
• An analysis crossing temperature records with population data found more than two‑thirds of Europe experienced daytime highs above 35°C between June 15 and 30, producing exposure on a scale comparable to or greater than the 2003 event.
• Health services and infrastructure were strained as hospitals saw surges in patients, deaths at home in France rose 91% for June 22–28 versus the prior week, and energy generation and other systems suffered interruptions and damage.
• Scientists say the scale and intensity of the episode are almost certainly linked to climate change, and authorities caution that official mortality totals are provisional, that counts will be revised, and that adaptation and public‑health measures remain urgent.
