In September 2024, an extraordinary weather phenomenon was registered in Austria: It was the most precious September since the beginning of the measurements in 1858. According to Geosphere Austria, more than twice as much precipitation fell this month as usual, with an increase of impressive 118 percent compared to average. These massive rainfall led to severe floods and degrees of mura in many regions of the country.

The new record values of over 447 millimeters of precipitation at more than 80 weather stations, including St. Pölten and Langenlebarn, are particularly striking, both of which were demonstrably higher in quality assurance than any previous measured values. Here the previous record in St. Pölten was 202 millimeters for 1937.

a sudden change in weather

In the second week of September, for example, there was a dramatic cold air slump that occurred after a long heat wave in the east of Austria. This cold chipping sponsored a low pressure area, the rainy amounts of 100 to 400 millimeters, especially between September 12 and 16, distributed across the country. The rain was particularly pronounced in the northeastern federal states: Upper Austria reported precipitation quantities of up to 204 percent above the average for the month.

The snow, which fell at high altitudes of about 600 meters, was also surprising. In Styria, for example, five centimeters of snow were registered at a height of 637 meters on September 13, an extraordinary sight in a month in which snow is normally rare. In higher locations such as the Rudolfshütte in Salzburg, the snow height reached a new record for September on September 17 with 145 centimeters.

advantages and challenges of the extreme weather

However,

September started with a heat wave that brought new record temperatures in many places. At 35.9 degrees in Bad Deutsch-Altenburg on September 3, the all-time record of 36.0 degrees was just missed, which was measured in 2015. These alternating weather conditions seem to be part of a larger pattern of climate changes that are closely observed by meteorologists and climatologists.

Total September 2024 brought an average to slightly above -average monthly medium temperature. The air conditioner Alexander Orlik said that the average temperatures in the lowlands were 0.7 degrees above the average of the past three decades. A place in the upper third of the measurement history is attested to September: the 43rd warmest month in 258 years, while the mountain regions were cooler than normal due to the cold weather.

This month was an interesting and sometimes challenging combination of extreme weather events that produced a variety of natural phenomena, and the exact course and the effects remain the subject of numerous scientific studies.
