Germany recorded a record 15,800 heat-related deaths during the summer of 2024 [1], according to the Robert Koch Institute (RKI).
The figures highlight the increasing vulnerability of European populations to extreme temperature spikes. As heatwaves become more frequent and intense, public health infrastructure faces growing pressure to protect elderly and high-risk citizens.
The RKI, Germany's national public health institute, published the findings on Thursday, Aug. 22, 2024 [2]. The report focused on data collected up to mid-August of that year [2]. The agency said it used statistical models to determine the death toll, comparing the number of deaths during heatwave weeks against deaths recorded during non-heatwave weeks [2].
This surge in mortality occurred as part of a broader pattern of extreme weather across the European continent. The RKI said it quantified the deaths as excess mortality, the number of deaths above what would be expected under normal weather conditions [1].
While the report specifically addresses the German domestic impact, it notes that the trend is linked to the broader European heatwave [3]. The 15,800 deaths [1] represent a record high for the country, reflecting the severity of the temperature peaks experienced throughout the season.
Health officials have previously said that extreme heat puts significant strain on the cardiovascular and respiratory systems. This vulnerability is often magnified in urban areas where the heat-island effect keeps nighttime temperatures high, preventing the body from recovering between heat spikes.

The reliance on excess mortality modeling by the RKI indicates that heat-related deaths are often indirect, caused by the exacerbation of existing chronic conditions rather than single-event heatstroke. This record suggests that previous urban planning and public health warnings may no longer be sufficient for the current scale of European temperature extremes.
