September 2024: Records in rain and snow in Lower Austria

September 2024 will go down in the history books as an extraordinarily wet month because he set records in various regions of Austria. In particular, the heavy rains in the middle of the month led to new rainfall records at over 80 weather stations at Geosphere. In St. Pölten and the small village of Langenlebarn, around 447 millimeters rain were measured, which significantly exceeds the previous records of 2013 and 175 millimeters in Langenlebarn in the Lower Austrian state capital.

The extraordinary weather phenomenon began after a long -lasting heat wave, especially in the east of Austria, led to a dramatic cold air slump. A low pressure area that was raised from Italy brought huge amounts of rain, especially between September 12 and 16. The precipitation varied in Austria between 100 and over 400 millimeters, with Lower Austria and Vienna in particular affected by an average value of 290 percent.

precipitation data and temperature changes

This month was not only shaped by excessive precipitation, but also by remarkable temperature differences. While the heat wave gave many weather stations at the beginning of the month that recorded the new September highest temperatures, the cold air slump brought snow into some mountain regions and valleys. An example of this is the Wetterstation Hall in Styria, which reported five centimeters of snow at a height of 637 meters on September 13. Snow at these altitudes is extremely rare in Austria in September and only occurs every five years.

The month of September 2024 was also characterized by large rainfall in Upper Austrian and Lower Austrian valleys, which were three times as high as the values of an average September. The number of precances in Upper Austria rose by 204 percent, while the values in Vorarlberg, Tyrol and Carinthia deviated by 58, 69 and 74 percent.

The amounts of record snow in higher regions were also remarkable. For example, in the Rudolfshütte in Salzburg at 2,320 meters on September 17, the highest September snow height has been reached since the start of the measurement, with an impressive 145 centimeters. This event is unusual and shows how extreme the weather events were in September 2024.

temperature course and its importance

The temperature development of September 2024 was another part of this weather -related roller coaster. While the temperatures at various weather stations set up new records for the autumn month, the maximum value was 35.9 degrees, just below the Austrian record from 2015. Climatologist Alexander Orlik explained that the average temperatures in the lower regions were 0.7 degrees above the average from 1991 to 2020

The entirety of these weather phenomena puts September 2024 in the context of an inconsistent climate. The unusual precipitation and the subsequent cold phase suggest that extreme weather events could occur more and more in the future. The average temperatures and precipitation were taken into account this month, taking into account long -term measurements, which is an important basis for other climatic analyzes.
