In 2023, meteorologists recorded the warmest September in the Alps since weather records began. This is reported by the German Weather Service (DWD), Geosphere Austria and MeteoSchweiz in the current edition of their “Alpine Climate” publication series.
The scientists summarize that there were many temperature records and extreme precipitation in the summer half of 2023.
At the beginning of August, record rainfall fell in southern Austria and the neighboring Alpine regions of Italy and Slovenia, which led to severe flooding. The scientists said there were also several daily and monthly records for temperatures from July 2023 onwards. After a first heat wave in July, another one followed at the end of August with new record temperatures, for example 37.6 degrees Celsius in Sion, Switzerland.
