WIESELBURG, AUSTRIA / RankWire.AI / – Austria experienced its highest July temperature on July 31, when Wieselburg reached 40.3 degrees Celsius. This temperature surpassed the previous July record of 39.7 degrees, set in Dellach im Drautal in 1983. GeoSphere Austria verified the new monthly peak during a heatwave centered on eastern parts of the country. Austria’s absolute temperature record remains 40.5 degrees, recorded at Bad Deutsch-Altenburg in August 2013.

The July temperature milestone followed a June characterized by widespread and sustained extreme heat. According to GeoSphere Austria, 157 out of its 277 weather stations recorded new maximums for June. Additionally, 66 stations registered their highest temperature for any month. On June 28, Vienna hit 40.0 degrees, with Bad Deutsch-Altenburg reaching 40.1 degrees the next day. Several low-altitude regions endured 10 to 14 consecutive days with temperatures exceeding 30 degrees.
The Wegener Center at the University of Graz approximated that the combined socioeconomic losses from the June and late July heatwaves totaled about €1.4 billion. This initial estimate accounts for health impacts, productivity losses, agricultural damage, infrastructure stress, and increased cooling demands. It also considers ecological effects and pressure on public services. Notably, this figure does not reflect a final government assessment or insured losses; insurance data only encompass damage covered under active policies.
Heatwave magnitude exceeds previous Austrian record
The Wegener Center evaluated the events through area-degree days, which integrate heat intensity, duration, and geographic extent. Researchers estimated around 16,700 area-degree days for the June heatwave. Their analysis placed the late July episode between 22,700 and 25,000. Austria’s prior benchmark was during a 24-day heatwave in July and August 2013, which reached about 22,100 area-degree days across land below 1,500 meters in elevation.
Simultaneously, extreme temperatures led to a notable rise in heat-related fatalities. The Austrian Agency for Health and Food Safety estimated 395 such deaths in June 2026, marking the highest June total since the agency began tracking this measure. Heat-related mortality reflects deaths exceeding typical expectations during periods of abnormally high temperatures. Importantly, it does not require heat to be listed as the sole cause on each death certificate.
Continued rainfall shortages intensify national drought situation
Following months of unusually dry conditions, Austria confronted the heatwave amid persistent drought. From January 1 to July 27, the country received approximately 426 millimeters of rainfall, compared to the long-term average of 609 millimeters for that period, representing a near 30% shortfall. Authorities described the first seven months of 2026 as the driest comparable period since at least the early 1900s. Notably, lower Austria, Vienna, and northern Burgenland reported some of the highest rainfall deficits in the nation.
Prolonged high-pressure systems, intense sunlight, and limited rainfall contributed to increased evaporation during late spring and summer. These conditions diminished soil moisture and exerted additional stress on crops, rivers, forests, and water reserves. Climate records in Austria indicate that heatwaves have become more frequent, longer-lasting, and more intense over recent decades. Between the 1980s and the 2020s, average maximum temperatures during heatwaves increased by roughly three degrees. The new July record further confirms Austria’s ongoing trend toward more extreme heat events.
