The weather Lots of rain and little sun in September

It rained significantly more than usual in September. As so often this year, the sun also appeared less frequently than usual.

On Monte Generoso, 338 millimetres of rain were measured, as SRF Meteo wrote on Monday. In Sempach LU, the wettest September since measurements began was recorded with 213 millimetres of rain. In Hallau SH, 255 percent more rain fell than usual. Unlike many countries in Central and Eastern Europe, Switzerland was spared widespread flooding. However, there was localized flooding in the canton of Zug and in the west of the canton of Zurich.

It was not only wet, but also cold. The first icy day of the season was recorded in the middle of the month. According to SRF Meteo, the temperature did not rise above freezing point all day. In Arosa GR, as much as 34 centimetres of fresh snow fell. This was the fourth largest amount of fresh snowfall in Arosa in the first half of September.

Only a little sunshine

This was not the first time this year that the sun appeared sporadically. Across the country, the hours of sunshine were well below the norm, according to the report. Nyon VD was the sunniest place with 150 hours of sunshine. However, this is also well below the norm.

Not all of September was damp and gray. At the beginning of the month, there was also some midsummer in some regions. In the canton of Schaffhausen, at Zurich Airport and in the Oberaargau region of Bern, the warmest September days in history were measured locally, wrote SRF Meteo. Compared to the previous year, the temperature in September was four degrees lower on average and half a degree lower on average over the last 30 years.
