Many summer days – May is one of the warmest in the history of measurements


May 2022 will go down in measurement history in Austria as one of the ten warmest months of May. In some places it was even the warmest May since measurements were taken – especially in the western half of Austria.

“Looking at the entire lowlands of Austria, it was the seventh warmest May in the history of measurements, in the mountains the fifth warmest,” said ZAMG expert Alexander Orlik. While the “happy month” for the past three years was relatively cool, this year it was clearly too warm.

The monthly average (average of all day and night temperatures) was 16.7 degrees in Bregenz. The previous record set in May here was 16.6 degrees in 2018. The series of measurements goes back to 1870.

Most days from 25 degrees in Innsbruck
An above-average number of summer days was also counted, so days with at least 25 degrees. This year there were 13 summer days in Innsbruck, 12 in Klagenfurt, 11 in the inner city of Vienna, 9 in Bregenz, Graz and Eisenstadt, 8 in Linz and 7 in Salzburg and St. Pölten. In an average May in the recent past (average 1991-2020), the ZAMG recorded between four and nine summer days in the capital cities. In the period 1961 to 1990 there were even fewer with an average of only about two to five summer days in May.

Feldkirch had a monthly average of 16.6 degrees in May 2022. The previous record set in May was 16.5 degrees in 2018, the series of measurements started in 1876. Lienz recorded a monthly average of 16 degrees. The previous record was 15.5 degrees in 1868 (series of measurements since 1853). Obergurgl at 1942 meters above sea level had a monthly average of 8.1 degrees, just above the previous record of eight degrees in 1868 (series since 1851). At Sonnblick (3109 meters above sea level) it had a monthly average of 0.0 degrees, the previous record of May was minus 0.5 degrees in 1958 and 2018 (measurement series since 1887).

Regional often too dry
The duration of sunshine (minus three percent) and precipitation (minus seven percent) were in the range of the long-term average. Regionally, however, it remained much too dry, especially in Vorarlberg, in Carinthia south of the Drau, in large parts of Upper Austria and Lower Austria, in Vienna and in the north of Burgenland. Here it rained only half of an average May.
