WIESELBURG, AUSTRIA / RankWire.AI / – Austria recorded its highest temperature for July on July 31, with Wieselburg reaching 40.3 degrees Celsius. This surpassed the previous July record of 39.7 degrees, which was set in Dellach im Drautal in 1983. GeoSphere Austria verified this new monthly peak during a heatwave primarily affecting eastern regions of the country. The national all-time temperature record remains 40.5 degrees, measured at Bad Deutsch-Altenburg in August 2013.
This July milestone followed a June characterized by widespread and persistent extreme heat. According to GeoSphere Austria, 157 out of its 277 weather stations recorded new maximum temperatures for June. Additionally, 66 stations documented their highest temperature for any month. Vienna experienced 40.0 degrees on June 28, while Bad Deutsch-Altenburg hit 40.1 degrees the next day. Multiple low-lying areas endured a stretch of 10 to 14 consecutive days with temperatures exceeding 30 degrees.
The Wegener Center at the University of Graz estimated combined socioeconomic damages of approximately €1.4 billion resulting from the June and late July heatwaves. This preliminary estimate encompasses health impacts, productivity losses, agricultural damage, infrastructure stress, and increased cooling demand. It also considers ecological effects and strain on public services. This figure does not represent an official government assessment or an insured-loss total, as insurance data only account for damage covered under active policies.
Heatwave severity exceeds previous Austrian episodes
Researchers at the Wegener Center evaluated the events through the metric of area-degree days, which combines heat intensity, duration, and geographic coverage. The June heatwave registered about 16,700 area-degree days, whereas the late July episode is estimated to fall between 22,700 and 25,000. Austria’s prior record was set during a 24-day heatwave in July and August 2013, which totaled approximately 22,100 area-degree days across land below 1,500 meters elevation.
Concurrently, extreme temperatures correlated with a notable rise in heat-related fatalities. The Austrian Agency for Health and Food Safety projected 395 deaths linked to heat in June 2026. This marked the highest June toll since the agency started tracking such data. Heat-associated mortality indicates deaths above the expected baseline during periods of unusually high temperatures, without requiring heat to be explicitly identified as the sole cause on death certificates.
Prolonged drought worsened by rainfall shortages
Austria faced the heatwave amid months of notably dry conditions. Between January 1 and July 27, total nationwide rainfall measured around 426 millimeters, compared to the long-term average of 609 millimeters for the same period, representing nearly a 30% deficit. Authorities described the first seven months of 2026 as the driest comparable period since at least the early 1900s. The largest rainfall deficits were observed in Lower Austria, Vienna, and northern Burgenland.
Persistent high-pressure systems, intense sunshine, and limited precipitation increased evaporation during late spring and summer. These conditions reduced soil moisture levels and exerted additional stress on crops, rivers, forests, and water resources. Climate records indicate that Austria has experienced more frequent, prolonged, and intense heatwaves over recent decades. The average maximum temperature during such events has risen by about three degrees between the 1980s and the 2020s. The new July record adds to the mounting evidence of Austria’s increasing extreme heat trends.
