The weekend and Monday bring lots of sunshine and summery temperatures. During the day it will be unusually warm, with highs between 23 and 28 degrees. In some cases even 30 degrees are possible, especially on Sunday and Monday, Geosphere Austria informed on Friday. A hot day on Sunday would be ten days earlier than the previous record.
The first “30” took place on April 17, 1934 in the city of Salzburg. The second earliest date for a hot day in Austria was on April 20, 2018, also in the city of Salzburg. The highest temperatures measured in April are around 30 degrees in all federal states and almost all come from the end of the month. Lower Austria holds the temperature record for April with 32.0 degrees on April 28, 2012 in Waidhofen/Ybbs, while in Upper Austria the peak value was 31.8 degrees in Braunau/Ranshofen on the same date. The highest temperature in Salzburg in April was 31.5 degrees on April 27, 2012 in Salzburg/Freisaal.
In Vorarlberg, 31.2 degrees on April 28, 2012 are in the history books in Bregenz, and in Tyrol, 31.2 degrees on the same day in Kufstein. The Vienna April record was 31.2 degrees on April 30, 2012 at the Innere Stadt measuring point, closely followed on the same date by Burgenland with 31.0 degrees in Neusiedl/See. The highest temperature in April in Styria was a long time ago, on April 24, 1968, when it was exactly 30.0 degrees in Leibnitz. In Carinthia there has never been a “30” in the fourth calendar month, here the temperature record was 29.9 degrees on April 7, 2011 in Pörtschach.
15 degrees above typical values
The predicted high temperatures for the next few days are around ten to 15 degrees above the typical values for the beginning of April. Due to global warming, very warm weather patterns are occurring earlier and earlier, Geosphere informed. The 30 degree mark is now reached significantly earlier in average years than it was a few decades ago.
“In the recent past, in the climate period 1991 to 2020, the first 30s in Austria were reached on average on May 19th, with the typical range of fluctuations extending from the beginning of May to the beginning of June,” explained Alexander Orlik, climatologist at Geosphere Austria, ” In the climate period 1961 to 1990, the 30 degree mark was reached on average on May 30, with a typical fluctuation from mid-May to mid-June.”
The mild southerly current will bring Sahara dust back to Europe in the next few days. According to the current forecast, this will not be as severe in Austria as it was last weekend and the highest concentrations of the dust cloud will move over Spain, France and Germany on Sunday.
