Spring in Switzerland

The weather in the Alps

The Alps are a weather world of their own. Nowhere is the weather as unpredictable as here. The alpine massif forms the climatic dividing wall between north and south. In addition, you will find distinct local weather patterns on steep slopes and in valleys. The higher, the colder. This law of nature prolongs the cold season and aggravates the local climate. In addition, sudden weather changes are common and can be dangerous. That's why experienced climbers and hikers keep a respectful eye on alpine weather. When planning your excursion, the usual weather forecasts are part of the basic equipment. Good weather apps and the many live webcams are a valuable asset.

Temperatures in Switzerland

In the summer months of July and August, the average daily temperature ranges between 18 and 28 °C. In winter it varies between -2 and 7 °C. Temperatures around 15 °C sometimes climb to 20 °C and dominate both spring and autumn. The following rule of thumb applies: every 100 m upwards, there is a drop in temperature of about 1 °C. Thus, in high alpine locations, you will encounter thick layers of snow even in summer. North of the Alps it is cooler than in sunny Ticino. Southern slopes, wide valleys and lakes, on the other hand, receive more sun Thanks to these different temperatures, both fir and palm trees grow in Switzerland. The warmest areas include Lake Geneva, the Rhone Valley and the valleys in the south of Ticino. The coolest are naturally all places in the high mountains. Here you can find an overview of the temperatures as well as the precipitation of individual main places in Switzerland:
