Germany recorded nearly 9,800 heat-related deaths by July 19, 2026, exceeding any full-year total since 2016 and surpassing the previous high of about 9,000 deaths in 2018 [1, 2, 3].

A severe heatwave in late June, with temperatures soaring above 40°C, accounted for more than half of the fatalities, causing over 5,000 deaths that month alone [1, 2, 4]. Another wave of heat-related deaths followed between July 13 and July 19, with around 1,900 fatalities reported during that week [2].

The deaths disproportionately affected older people. Among the fatalities, 5,420 were aged 85 and over, 2,460 were between 75 and 84, 1,260 were 65 to 74, and 630 were under 65 years old [1, 3]. The Robert Koch Institute noted that heat rarely causes death directly but often contributes alongside existing conditions such as cardiovascular, lung, and kidney diseases [2].

Despite the extreme heat, air conditioning prevalence remains very low in Germany at about 3%, with only around 4% of new homes equipped with AC [4]. Cultural and environmental factors, including concerns over electricity use, CO2 emissions, and preservation of historic building facades, limit AC adoption [4]. Schools can reach nearly 40°C during heatwaves, yet electric fan use is strictly restricted by authorities due to safety and legal reasons [4].

The severe heat also triggers significant economic losses, estimated at 430 million euros annually from reduced productivity [4]. Amid these challenges, German officials have discussed expanding protections against extreme heat. Calls for greater investment aim to keep hospitals, nursing homes, and kindergartens cool, especially during prolonged heatwaves [1, 3].

The Robert Koch Institute’s latest data make clear the deadly impact of the summer’s heat and underline ongoing debates on improving public health responses. A rising frequency of heat extremes poses growing risks, particularly to vulnerable populations.

The situation remains critical as summer continues, with authorities monitoring conditions closely and seeking urgent solutions to mitigate further heat-related fatalities [1, 2, 3].
