European heatwaves cause over 30,000 excess deaths as Germany records 14,000 fatalities

European excess mortality figures

European mortality surveillance data indicates that recurring heatwaves caused tens of thousands of excess deaths across the continent during the summer of 2026. The European mortality monitoring platform EuroMomo estimates that more than 32,000 excess deaths occurred across Europe between mid-July and mid-August alone based on preliminary figures. Total continental estimates show that at least 30,000 additional people died since the beginning of the summer season. Mortality surged most sharply during two distinct early-season episodes that coincided directly with extreme heatwaves. EuroMomo recorded approximately 16,000 excess deaths across Europe during the final week of June, followed by roughly 8,000 additional deaths during the first week of July.

National tallies across Western Europe

EuroMomo does not provide an official breakdown of excess deaths by individual member state, but national public health authorities have published separate preliminary figures. These national health reports cover observation periods extending roughly from late May to August. A review of these official national figures by Agence France-Presse calculated 33,000 deaths that were either directly tied to heat or categorized as excess mortality. This total spans only eight countries: Germany, Austria, Belgium, England, France, the Netherlands, Portugal, and Spain. The compiled records show that the mortality impact was distributed unevenly across Western Europe depending on regional heat intensity and demographic vulnerabilities.

German mortality and temperature peaks

In Germany, the Robert Koch Institute stated on Thursday, 20 August 2026, that an estimated 14,000 people died from heat-related causes over the course of the summer. This figure represents Germany's highest heat-related death toll in the past ten years, exceeding the prior ten-year high of approximately 8,900 deaths. The mortality in Germany was heavily concentrated in the last week of June, when local temperatures climbed above 41 degrees Celsius. The Robert Koch Institute attributed 9,600 of the nation's 14,000 total heat fatalities to that single week of extreme heat, reflecting severe physiological strain during peak temperatures across urban and rural areas.

Surveillance coverage and statistical modeling

The continental figures remain preliminary and are expected to change as EuroMomo refines its statistical models over the coming weeks. The current EuroMomo monitoring dataset incorporates official death records from 23 European countries, leaving parts of Eastern Europe unrepresented in the aggregate total. Public health institutes measure heat-related mortality through statistical modeling rather than individual death certificates. Because heat cannot be entered on death certificates as a standalone cause of death, it does not appear directly in standard cause-of-death registries. Instead, researchers model the death toll by comparing overall mortality during hot summer weeks with mortality in baseline periods without heat. Acute conditions like heatstroke cause only a small share of direct fatalities, with most deaths occurring when elevated temperatures worsen pre-existing cardiovascular, pulmonary, or renal illnesses.
