Spatial climate normals

The maps of normal values show the long-time averages for temperature, precipitation, sunshine duration and various climate indicators in Switzerland. Several normal periods as well as their differences are illustrated. The spatial illustration is based on a 2 km grid point data set, calculated using all available measurements from ground-based measuring stations.

MeteoSwiss provides monthly and annual maps for normal periods 1961-1990 and 1991-2020.
