Autumn Again Too Warm

On some days, the temperatures were even in the record range. For instance, on September 3rd, with 35.9 degrees in Bad Deutsch-Altenburg, the nationwide September and autumn record was narrowly missed (36.0 degrees in September 2015 in Pottschach in Lower Austria). On Sonnblick, November 1st saw the highest November temperature since measurements began here in 1886, at 7.1 degrees.

Autumn in Top 20

"The autumn of 2024 is in the preliminary balance in the lowlands of Austria 0.7 degrees above the average of the climate period 1991 to 2020, in the summit regions by 1.1 degrees," said climatologist Alexander Orlik, "this results in the lowlands place 13 in the series of the warmest autumns of the 258-year measurement history and in the mountains place 14 in the 174-year mountain measurement series." Compared to the climate period 1961 to 1990, the autumn of 2024 in the lowlands was even 1.4 degrees and in the mountains 1.6 degrees above the average.

The amount of precipitation in the autumn of 2024 was 45 percent above average in the nationwide evaluation. The main reason for this was the extreme rain in September, as October was average and November very dry. The record rain in September in the east and north of Austria also resulted in individual record values in the precipitation balance for the entire autumn. For example, in Lower Austria, Langenlebarn recorded a new autumn record with around 520 millimeters of precipitation (old record 225 millimeters in autumn 2007), St. Pölten with around 510 millimeters (old record 355 millimeters in autumn 1950) and Zwettl with around 320 millimeters (old record 274 millimeters in autumn 1922).

Snow in Autumn

In the autumn, there was already the first snow in the high mountains. Some cold air intrusions also caused snowfall down to low altitudes. However, over the entire autumn, the number of days with snow cover was below average. For example, in altitudes between 1,000 and 2,500 meters above sea level, there were 15 to 30 percent fewer days with snow cover than the multi-year average.
