WIESELBURG, AUSTRIA / RankWire.AI / – Austria experienced a new temperature record for July on July 31 amid widespread extreme heat across eastern regions. A weather station located in Wieselburg, Lower Austria, recorded a high of 40.3 degrees Celsius, surpassing the previous July record of 39.7 degrees registered in Dellach im Drautal in 1983. GeoSphere Austria validated this monthly temperature peak. The reading remained below Austria’s all-time high of 40.5 degrees, which was set in August 2013.
This latest temperature milestone followed a notably scorching June across much of Austria. Out of 277 weather stations under observation, 157 recorded new maximum temperatures for June, and an additional 66 stations experienced their highest temperature ever recorded for any month. Vienna reached 40.0 degrees on June 28, while Bad Deutsch-Altenburg hit 40.1 degrees on June 29. Numerous lower-altitude regions also endured between 10 and 14 days of temperatures exceeding 30 degrees.
Scientists from the University of Graz’s Wegener Center approximated that the heatwaves in June and late July resulted in socioeconomic damages totaling approximately €1.4 billion. This estimate encompasses health impacts, reduced workforce productivity, agricultural losses, infrastructure strain, and increased cooling demands. It also accounts for pressures on ecosystems and public services. The figure does not represent an official government damage assessment, nor does it reflect insured losses, which are limited to claims covered by insurance policies.
Heat intensity surpasses previous national record
The study measured the severity of both heatwaves using area-degree days, a metric that combines temperature, duration, and geographic extent. The June event accumulated around 16,700 area-degree days. The late July heatwave was estimated to fall between 22,700 and 25,000 area-degree days. Austria’s prior benchmark was based on a 24-day heatwave during July and August 2013, which registered roughly 22,100 area-degree days across regions below 1,500 meters in elevation.
The early summer heat also coincided with a significant increase in heat-related fatalities. The Austrian Agency for Health and Food Safety reported 395 such deaths during June 2026, marking the highest June figure recorded since the agency began tracking this data. Heat-related mortality indicates deaths exceeding expected levels during periods of extreme heat. However, it does not require heat to be the sole medical cause listed on death certificates.
Intense drought conditions amplify stress across Austria
The country entered the heatwave after months of below-average rainfall. From January 1 to July 27, total nationwide precipitation reached about 426 millimeters, compared to an average of 609 millimeters for the same period, indicating a shortfall of nearly 30%. Authorities have classified the first seven months of 2026 as the driest period since at least the early 20th century, with Lower Austria, Vienna, and northern Burgenland experiencing some of the most severe rainfall deficits.
Persistent high-pressure systems, intense sunshine, and scarce rainfall increased evaporation rates through late May, June, and July. These conditions depleted soil moisture and strained agriculture, rivers, forests, and regional water supplies. Climate records show that heatwaves are now more frequent and last longer than in previous decades, with average peak temperatures during such events rising by roughly three degrees between the 1980s and the 2020s. Austria’s latest July temperature record underscores a clear trend of intensifying extreme heat episodes.
