Overview
- GeoSphere Austria reported a national record temperature of 41°C measured in the Stammersdorf district of Vienna on Aug. 4, 2026.
- Subsequent readings pushed highs further in the region with 41.2°C reported at Bad Deutsch-Altenburg in Austria and 41.4°C recorded in Kamenica nad Hronom in Slovakia, according to national weather services.
- The spike follows a fourth-warmest July for Austria and extreme dry conditions at some stations where precipitation deficits reached about 90 percent, worsening drought stress.
- Farmers face tangible impacts as apricots are ripening roughly 20 days earlier than the 1961–1991 average and Agriculture Minister Norbert Totschnig warned that drying pastures are making livestock feed increasingly difficult to secure.
- The heatwave has reduced foot traffic for businesses in Vienna, stretched firefighting resources and fits scientists' warnings that climate change is making European summers hotter and drier, increasing the risk of more frequent extreme events.
