Summer 2025: Austria experiences record heat and weather drama!

On September 2nd, 2025, the summer balance for the Austrian weathermen will arrive. The summer of 2025 in Austria was around 1 degree warmer than the long-term average expected. This makes the summer one of the ten warmest in the history of measurements. The temperature deviations were particularly noticeable in the south of the country, where results of up to +3 degrees were even recorded in the Klagenfurt Basin. No wonder that Vienna recorded a summer that was too warm this year for the 29th time in a row. A look at the individual months shows: June was the warmest in history for some regions with exceptionally high temperatures. This led to a record-breaking heat wave, which was the longest heat wave since records began in Klagenfurt between the end of June and the beginning of July.

However, in July, rain and thunderstorms returned. According to meteorologist Jürgen Schmidt, this month was marked by extreme rainfall, which provided a welcome cooling effect, and there were sometimes abrupt temperature changes. This was the first completely different character after the hot weeks of June. In August, western Austria again experienced hot days, while the country as a whole was only slightly above average. The maximum temperature in summer in Feistritz ob Bleiburg reached a remarkable 38.3 degrees.

Changeable weather conditions and regional differences

The weather situation this summer was characterized by changeability, with regular periods of sunshine and thunderstorms. The low pressure areas that moved from the Atlantic to Central Europe not only brought rain, but also caused sometimes surprising drops in temperature. This was particularly the case in July, as repeated showers and thunderstorms caused fluctuations in the daily maximum values. Meteorologists emphasize that forecasts for these weather phenomena are often inaccurate because thunderstorms can usually only be predicted a few hours in advance.

A different picture emerges with regard to precipitation. The South, as previously mentioned, struggled with extreme drought, while July was wet across the country. According to GeoSphere Austria, the rainfall varied greatly across regions: Our friends in Deutschlandsberg in southwest Styria in particular experienced the driest summer since measurements began in 1896. In contrast, other regions consistently had average or even positive values ​​for sunshine duration. In Puchberg am Schneeberg, the second sunniest summer since 1977 was documented.

Looking into the future and the big picture

These current developments are not only fascinating weather phenomena, but are also closely related to longer-term climate changes. GeoSphere Austria analyzes and monitors such climatic features using a comprehensive meteorological measurement network. This initiative aims to place current weather events in the broader context of climate change and to objectively examine their consequences for Austria.

All in all, the summer of 2025 shows that both heat and precipitation represent an ongoing challenge and therefore also an issue of climate change. So as we look ahead to the next few months, the question remains: How will the weather develop in Vienna and beyond? Meteorologists remain curious about upcoming restrictions and changes in the weather situation.
