"With its strange situation (surrounded by high mountains), this city has the advantage of a beautiful port and considerable shipping, but also the disadvantage that once on land one cannot get to the city without great inconvenience. This is because the weather in the vicinity of these high mountains is extremely unpleasant and rainy. There has even evolved an expression that is always rains in Bergen, and we have not experienced anything to counteract this saying." (a quote by the Dutch professor Fabricius after a visit to Bergen in ca. 1780).
Few other places in Hordaland, or even the whole country, get as much rain as in the Samnanger mountains. The mountains here simply attract wetness. The weather station on Kvitingen has continuous measurements all the way back to 1900, and the measurements have documented several records for the county. The station is therefore much used as a reference for the rainfall in western Norway.
Børtveit is known to be a place with a lot of rain. We must go to Samnanger or Indre Matre to find a higher rainfall. The average rainfall on Børtveit is 2871 millimetres, Slåtterøy has only 1328 millimetres and Fitjar 1610 millimetres.
