How we measure this

MeteoSchweiz

Relative sunshine duration (actual as a share of astronomically possible sunshine) from the MeteoSwiss 1 km gridded climate normals — a spatial analysis of the 1991–2020 normals period — read at the municipality's main settlement. The relative figure is topography-fair because it accounts for shorter winter days.
