WIESELBURG, AUSTRIA / RankWire.AI / – Austria experienced its highest temperature ever recorded in July on the 31st, as Wieselburg soared to 40.3 degrees Celsius. This surpassed the previous July peak of 39.7 degrees, set in Dellach im Drautal in 1983. GeoSphere Austria verified the record-breaking monthly temperature amidst a heatwave concentrated in the eastern regions of the country. The country’s all-time temperature record remains 40.5 degrees, measured at Bad Deutsch-Altenburg in August 2013.
The milestone in July followed a June characterized by widespread and persistent extreme heat conditions. According to GeoSphere Austria, maximum temperatures reached new heights at 157 of its 277 weather stations. Sixty-six stations also recorded their highest temperature ever recorded for any month. Vienna hit 40.0 degrees on June 28, while Bad Deutsch-Altenburg hit 40.1 degrees the day after. Several low-lying areas experienced 10 to 14 consecutive days with temperatures exceeding 30 degrees.
The Wegener Center at the University of Graz estimated that the combined economic and social damages from the June and late July heatwaves amounted to roughly €1.4 billion. This preliminary estimate accounts for health impacts, productivity losses, agricultural damage, infrastructure stress, and increased cooling demand. It also considers effects on ecosystems and public services. This figure does not represent an official government assessment or insured-loss total; insurance data only reflect damages covered by active policies.
Intensity of the heatwave surpasses previous Austrian records
Researchers at the Wegener Center assessed the severity of the events using area-degree days, which combine heat intensity, duration, and geographic coverage. They calculated approximately 16,700 area-degree days for the June heatwave. The late July event is estimated to fall between 22,700 and 25,000. Austria’s previous 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.
The extreme temperatures also led to a notable increase in heat-related fatalities. The Austrian Agency for Health and Food Safety estimated 395 deaths linked to heat in June 2026. This represented the highest June total since the agency began tracking this statistic. Heat-related mortality includes deaths that occur above expected levels during periods of unusually high temperatures. The calculation does not require heat to be listed as the sole cause on each death certificate.
Rainfall shortages intensify Austria’s ongoing drought conditions
Following months of unusually dry weather, Austria confronted the heatwave with significantly below-average rainfall. From January 1 to July 27, total nationwide precipitation amounted to approximately 426 millimeters, compared to a long-term average of 609 millimeters, indicating nearly a 30% shortfall. Authorities describe the first seven months of 2026 as the driest comparable period since at least the early 1900s. Notable deficits were recorded in Lower Austria, Vienna, and northern Burgenland.
Persistent high-pressure systems, intense sunshine, and limited rainfall led to increased evaporation during late spring and summer months. These conditions depleted soil moisture and exerted additional stress on crops, rivers, forests, and water reserves. Climate records in Austria show that heatwaves have become more frequent, prolonged, and intense in recent decades. The average maximum temperatures during such events have increased by roughly three degrees from the 1980s to the 2020s. The new July temperature record further emphasizes Austria’s ongoing trend of rising extreme heat levels.
