Germany approaches 10,000 heat-related deaths as record June temperatures hit

Estimates from the Robert Koch Institute place heat-related mortality in Germany at roughly 9,800 between early April and 19 July, edging close to the 10,000 mark and exceeding any full-year total since 2016. The surge follows an intense heatwave in the second half of June, when temperatures approached 42 °C in parts of the country, a period identified by the EU Copernicus climate service as the hottest June ever recorded in western Europe.

The Federal Statistical Office reported a 32 % increase in deaths during the week of 22-28 June versus the same week a year earlier, with the institute attributing at least 5,100 of those deaths to heat. Because heat often exacerbates existing cardiovascular, respiratory or kidney conditions, it is rarely listed as the direct cause on death certificates, so the institute calculates excess deaths by comparing observed mortality with expected seasonal baselines.

The majority of the estimated fatalities were among seniors: about 5,420 were aged 85 or older, 2,460 were 75-84, and 1,260 were 65-74, while roughly 630 victims were under 65. The current figure may rise as data from later July heatwaves are incorporated. Scientists link the increasing frequency and intensity of such deadly heatwaves to human-driven climate change.
