Berlin, September 17 – The Robert Koch Institute (RKI) has estimated that around 220 people in Berlin have died this year as a result of heatwaves. This number represents a substantial increase compared to the 40 heat-related deaths reported in 2025, as detailed in the institute’s latest weekly report.
Heat-Related Fatalities: A Look at the Past Decade
While the current figure is concerning, it does not set a record for the past decade. In 2018, an estimated 480 people in Berlin died due to heat, followed by 380 fatalities in 2019. The RKI’s current report covers the period from April 6 to September 6 of this year.
Nationwide Impact of Heatwaves
Across Germany, the RKI currently estimates approximately 16,000 heat-related deaths for the year. This is a considerably higher number than in previous years. The highest values since 2016 were recorded in 2018 with 9,200 heat-related deaths and in 2019 with 7,300. The figures for previous years may vary compared to earlier RKI data, as estimates are recalculated weekly.
Berlin’s Response to Extreme Heat
The city of Berlin has been grappling with increasingly frequent and intense heatwaves. Towards the end of June, temperatures in the capital reached nearly 40 degrees Celsius, contributing to the elevated number of fatalities. Public health officials and city authorities have been working to implement measures aimed at mitigating the health risks associated with extreme heat, particularly for vulnerable populations.
Challenges in Data Collection and Analysis
The RKI continuously refines its estimation methods for heat-related deaths, which can lead to adjustments in historical data. These ongoing recalculations ensure the most accurate possible assessment of the impact of heat on public health. The institute’s work is crucial for understanding the long-term trends and developing effective public health strategies.
Future Outlook and Prevention Strategies
As climate change continues to influence global weather patterns, cities like Berlin are expected to experience more frequent and severe heatwaves. This necessitates a proactive approach to public health, including improved early warning systems, increased access to cooling centers, and public awareness campaigns on heat safety. The RKI’s data serves as a critical tool for policymakers and healthcare providers in preparing for future heat events and protecting the health of the population.
