Where does the temperature data come from?

From the MeteoSwiss 1 km climate-normals grid ({year}), sampled at the main settlement. This is deliberately not the territorial average, which for Alpine municipalities is far colder because it takes in the high, glaciated terrain — Zermatt's village reads about 3.7 °C, its whole area about −3 °C.

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.
