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.

Frequently asked questions

Which municipality in canton Basel-Landschaft is the warmest?: Allschwil is the warmest municipality in canton Basel-Landschaft, at 11.1 °C annual mean (1991–2020).
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.
