How we measure this

MeteoSchweiz

Mean annual air temperature from the MeteoSwiss 1 km gridded climate normals — a spatial analysis of the 1991–2020 normals period — read at the municipality's main settlement rather than interpolated from distant stations. The figure describes the inhabited valley floor, not the surrounding peaks.
