On July 11, 15.7 degrees were recorded, as Geosphere Austria informed on Thursday. The record was caused by extremely warm air flowing from Africa across the Mediterranean to Austria. The air temperature of 15.7 degrees was around ten degrees higher than the values typical for this time of year. “In an average July, the maximum temperature at Sonnblick was 6.0 degrees in the period 1991 to 2020 and 4.2 degrees in the period 1961 to 1990,” explained meteorologist Gerhard Hohenwarter.
Since measurements began at the Sonnblick Observatory in 1886, this was only the fifth time that the 15-degree mark was reached. “All the values of at least 15 degrees have been on the Sonnblick in the recent past, which confirms the trend towards an ever warmer climate,” explained Hohenwarter.
The previous heat record at Sonnblick was 15.3 degrees on June 30, 2012. In August 1992 and July 1983 the measurements showed 15.0 degrees and in June 2023 already 15.1 degrees. The meteorologist suspects that there will be no more snow on the summit of the Sonnblick very early this year. Last year, the summit was already snow-free in July, earlier than ever before in the history of measurements.
“During heat waves, the snow depth on Sonnblick melts by around ten to 15 centimeters of snow per day,” says the expert. “Currently there is still around half a meter of snow on the Sonnblick and it might be gone by the beginning of August.” The early Ausapern has become much more common in recent years. “There used to be no snow on the Sonnblick for a short time at the end of August or the beginning of September.”
