How we measure this

MeteoSchweiz

Mean annual precipitation total from the MeteoSwiss 1 km gridded climate normals — a spatial analysis of the 1991–2020 normals period — read at the municipality's main settlement. Precipitation depends strongly on altitude and Alpine relief, which the 1 km grid resolves far better than a single distant station.
