Historic high temperatures are being recorded across Germany, Austria, and Switzerland, with mercury levels expected to climb further—reaching up to 42°C—by Sunday, 28 June 2026. A slight cooling is forecast starting Monday, 29 June.
New National Record in Germany
In Saarbrücken, located in North Rhine-Westphalia, a new all-time national record was set on Wednesday, 26 June 2026: 41.3°C. Across southern and southwestern Germany, temperatures hovered near 40°C, prompting repeated warnings from the German Weather Service (DWD) about “extreme heat” in the coming days.
“Extreme weather events like this have become more frequent due to the climate crisis—and are likely to intensify further,” the DWD stated in an official release. Data shows that the average number of days exceeding 30°C in Germany has risen significantly.
Weekend Forecast and Environmental Impact
Saturday is expected to bring temperatures between 36°C and 41°C—with isolated areas potentially hitting 42°C. Notably, water temperatures in the Main River reached 30°C at midday on Wednesday. While nighttime lows on Sunday are projected to remain unusually high—between 18°C and 25°C—storms and strong winds are anticipated overnight, particularly in northern and northwestern regions, possibly bringing severe weather.
Public Health and Safety Measures
Authorities are urging special precautions for vulnerable groups—including older adults and young children—to avoid heat-related illness. Recommendations include staying hydrated, limiting outdoor physical activity, and never leaving animals in parked cars—even briefly. Extra caution is also advised for those seeking relief in rivers, lakes, or the sea.
Economic Toll of the Heatwave
The intensity and duration of this heatwave carry mounting economic consequences—not only through health impacts and event cancellations, but also via lost productivity, infrastructure strain, supply chain delays, and rising energy costs.
“Heat is evolving from a meteorological phenomenon into an economic risk—requiring management on par with energy prices, supply chain disruptions, or geopolitical threats,” said Oliver Chandler, a strategic advisor at consulting firm Arthur D. Little, speaking to German broadcaster n-tv.
Allianz Trade, a credit insurance company, modeled various extreme scenarios and estimated that Germany could face €112.5 billion in heat-related losses by 2030 if such events continue at current rates. Its research also indicates a 3% drop in productivity for every degree Celsius above 30°C—particularly affecting industries reliant on manual labor, outdoor work, or temperature-sensitive processes.
