Germany recorded an estimated 5,120 heat-related deaths during the first half of the year, the Robert Koch Institute said Thursday, July 9, as the country’s public health agency warned that increasingly severe heat waves are becoming both a growing health emergency and a mounting economic burden.

According to the Robert Koch Institute’s latest weekly report, about 4,270 of the deaths were among people aged 75 and older. Women accounted for more fatalities than men, largely because they make up a greater share of Germany’s oldest population. The total already exceeds Germany’s annual average of roughly 2,900 heat-related deaths recorded between 2023 and 2025.

Most of the deaths occurred during a single week of extreme temperatures between June 22 and June 28, when much of Germany experienced its most intense heat of the year. The institute estimated that approximately 4,310 heat-related deaths occurred during that week alone, compared with about 810 deaths recorded from early April through June 21.

Temperatures climbed above 40 degrees Celsius (104 degrees Fahrenheit) in several parts of the country, with a new national high of approximately 41.3 degrees Celsius recorded near Saarbrücken. Public temperature displays in Berlin also registered about 41 degrees Celsius during the heat wave.

Germany’s experience reflects a broader trend across Europe. The Copernicus Climate Change Service, the European Union’s climate monitoring agency, reported Thursday that Western Europe experienced its hottest June on record, with average temperatures reaching 20.74 degrees Celsius. France, Belgium, Spain and the Netherlands together also reported more than 4,700 excess deaths during the same late-June heat wave.

Beyond the tragic loss of life, economists warn that extreme heat is increasingly weighing on Europe’s economy. Many German homes, hospitals and care facilities were built for a cooler climate and lack widespread air conditioning, forcing governments and businesses to invest heavily in cooling systems, building upgrades and public-health protections.

Allianz Trade estimates that climate-related losses could reduce the European Union’s cumulative economic output by 5% to 7% between 2026 and 2030. Germany alone could face economic losses of approximately $131 billion during that period, according to the insurer’s projections.

Industries that rely on outdoor labor face some of the greatest risks. Construction, agriculture, transportation and delivery services all experience productivity declines as temperatures rise, while recurring drought conditions continue to pressure crop yields and food production across Europe.

The European Central Bank has previously warned that prolonged drought and extreme heat contribute to higher food prices and slower economic growth. Officials increasingly view climate-related disruptions as both an inflation risk and a long-term challenge for economic planning.

As climate events become more frequent, businesses are also confronting rising insurance costs, higher energy demand for cooling, increased workplace safety requirements and disruptions to supply chains. Many economists now view extreme heat as an ongoing business risk rather than an occasional weather event.

German officials expect the death toll to increase further as additional reports from the hottest days of the summer are finalized.

For businesses, insurers and governments alike, Thursday’s report underscores that extreme heat is no longer simply an environmental issue—it has become an increasingly important economic challenge affecting productivity, infrastructure, healthcare spending and long-term growth across Europe’s largest economy.
