Austria is currently experiencing an unprecedented heatwave. According to Manuel Oberhuber of the ORF weather department, the nation has never seen such a warm night, as the extreme heat persists well into the evening hours across both urban centers and high-altitude regions.
Record-breaking temperatures across Austria
The current heatwave has pushed temperatures to historic highs. In Vienna, temperatures reached 40 degrees Celsius for the first time. So heiß war es österreichweit im Juni noch nie. It was the second-hottest day in Austria since the beginning of measurements after August 8, 2013, when 40.5 degrees were measured in Bad Deutsch-Altenburg in Niederösterreich.
Other regions also saw high figures. In Niederösterreich, Langenlebarn recorded 39.9 degrees, while Innsbruck reached 38.7 degrees. Oberösterreich saw highs of 38.2 degrees in Enns, Linz, and Wels. Additional high temperatures were reported in Eisenstadt (38.2 degrees), Mooslandl (37.4 degrees), and Bludenz (37.3 degrees).
The previous record for a warm night was 26.9 degrees Celsius, measured in the Vienna city center on August 2, 2017. The current heatwave has seen nighttime temperatures in the Vienna city center hit 26.1 degrees in the most recent measurement.
The impact of tropical nights
A “tropical night,” defined as a night with temperatures not below 20 degrees, was observed at 90 of GeoSphere Austria’s 280 weather stations on Monday. Urban areas are particularly vulnerable to these conditions because sealed surfaces and dense building structures prevent temperatures from dropping more significantly.
The phenomenon has extended beyond low-lying cities. GeoSphere climatologist Alexander Orlik noted that the air mass is so hot that tropical nights were observed at altitudes up to 1,000 meters. For example, the Kolomansberg (1,113 meters) in Salzburg did not see temperatures fall below 21.7 degrees.
While individual extreme events cannot be attributed to a specific cause, the World Climate Council indicates that the climate crisis is making extreme weather—including heatwaves and drought—more frequent and intense.
What to expect in the coming days
Meteorologists expect the heatwave to continue in the east and southeast of Austria, where temperatures could again reach 40 degrees on Monday. In the west, the heatwave is breaking with storms and humid conditions. Looking ahead to the second half of the week, Manuel Oberhuber noted that there will be “time to air out” buildings.

Frequently Asked Questions
What defines a “tropical night” in Austria?
A tropical night is defined as a night where the temperature does not drop below 20 degrees Celsius.
Why are cities more affected by the heat?
In dense urban areas, heated buildings and sealed surfaces prevent temperatures from dropping more significantly.
What are the recommended safety measures during this heat?
Health authorities recommend that individuals drink plenty of fluids and drink even without feeling thirsty to manage the strain caused by the extreme heat and humidity.
How are you managing the record-breaking temperatures in your local area?
