The temperature mark of 30 degrees is being reached earlier and earlier in Austria. In the meantime, the first 30s are measured on average a week and a half earlier than a few decades ago, as an evaluation by the Central Institute for Meteorology and Geodynamics (ZAMG) shows. According to the experts, this year it should be ready in the middle of the week.
The mid-May date is in line with the average for recent years, but around 40 years ago that would have been an earlier date. “In the period 1961 to 1990, the 30-degree mark was reached on May 30 on average, with a typical range of around mid-May to mid-June,” said ZAMG meteorologist Alexander Orlik. In the period 1991 to 2020, the first 30s occurred on May 19 on average. “The 30-degree mark is now being reached about a week and a half earlier,” says Orlik.
Even if the 30-degree mark tends to be reached earlier and earlier, the date of its arrival continues to fluctuate from year to year, as the past few years have shown: in 2021, the first 30 in Austria was reached at a similar time as this year. On May 10, 2021 it was 31.0 degrees in Salzburg Freisaal, 30.9 in Bad Ischl, 30.6 in St. Wolfgang, 30.5 at Salzburg Airport and 30.1 degrees in Golling.
In 2020 there was the first 30s of the year in the ZAMG measuring network on May 23rd, in 2019 on June 3rd. In 2018, the 30 degree mark was reached extremely early on April 20 (30.0 degrees Salzburg Freisaal). This was also the second earliest date in measurement history. The earliest 30s in the history of measurements was on April 17, 1934, also in the city of Salzburg.
