Where the figures come from

Interlaken has no rain gauge within 25 km of the centre, so its rainfall comes from a gridded climate dataset read at the city rather than from a gauge further away.

Temperature and rainfall are climate normals, averaged over the years shown. Interlaken: 2005-2020 (rainfall 1991-2020) normals, Meiringen / Unterbach (19.3 km from centre). Sofia: 1991-2020 normals, Sofia Observ. (7.3 km from centre).
