WIESELBURG, AUSTRIA / RankWire.AI / – Austria experienced a new temperature peak in July on the 31st as intense heat affected eastern regions. A weather station located in Wieselburg, Lower Austria, recorded 40.3 degrees Celsius. This measurement surpassed the prior July high of 39.7 degrees, noted in Dellach im Drautal in 1983. GeoSphere Austria verified the record for the month. The temperature stayed below the national record of 40.5 degrees, set in August 2013.
This recent record followed an extraordinarily hot June across much of Austria. Out of 277 weather stations monitored, 157 registered new maximum temperatures for June. An additional 66 stations recorded their highest temperatures ever recorded in any month. Vienna reached 40.0 degrees on June 28, with Bad Deutsch-Altenburg hitting 40.1 degrees one day later. Many regions at lower altitudes also experienced periods of 10 to 14 consecutive days with temperatures exceeding 30 degrees.
Researchers affiliated with the University of Graz’s Wegener Center estimated that the combined heatwaves in June and late July resulted in approximately €1.4 billion in socioeconomic damages. This estimate encompasses health impacts, reduced work productivity, agricultural losses, infrastructure stress, and increased cooling energy demands. It also considers ecosystem strain and pressure on public services. The figure is not a final government damage assessment and does not account for insured losses, which only cover claims under insurance policies.
Heat intensity surpasses previous national record
The assessment of both heatwaves utilized area-degree days, a metric that combines temperature, duration, and geographical extent. The June heatwave reached roughly 16,700 area-degree days, while the late July event was estimated to be between 22,700 and 25,000. Austria’s prior benchmark was a 24-day heatwave in July and August 2013, which measured about 22,100 area-degree days across land areas below 1,500 meters elevation.
The early summer heatwave coincided with a significant increase in deaths related to heat. The Austrian Agency for Health and Food Safety projected 395 such fatalities during June 2026, marking the highest June figure recorded since the agency started tracking this data. Heat-associated mortality reflects deaths above expected levels during extreme temperature periods, without requiring heat to be the sole medical cause listed on death certificates.
Drought conditions intensify pressure across Austria
The heatwave followed months marked by below-average rainfall nationwide. From January 1 through July 27, total precipitation reached approximately 426 millimeters, whereas the average for this period is 609 millimeters, resulting in a deficit of nearly 30%. Authorities have characterized the first seven months of 2026 as the driest since at least the early 20th century. Regions such as Lower Austria, Vienna, and northern Burgenland experienced some of the most severe rainfall shortages.
Persistent high-pressure systems, intense sunshine, and limited rainfall elevated evaporation rates through late May, June, and July. These conditions led to reduced soil moisture, stressed crops, and strained rivers, forests, and regional water supplies. Climate data from Austria indicates that heatwaves are occurring more frequently and lasting longer than in previous decades. The average peak temperatures during such events have risen by roughly three degrees from the 1980s to the 2020s. The recent record set in July highlights Austria’s ongoing trend of intensifying extreme heat episodes.
