Bergen is a wonderfully city.
I remember. I lived at a families place in my 20s. So nice.
It doesn't surprise me.
Annual precipitation is approx. 2,500mm, distributed over some 230 days.
The wettest place in Norway, on average, is Brekke a couple of hours north of Bergen, receiving some 3,500mm annually.
As I used to say when living in Bergen if a tourist asked me if it always rained there - 'No idea, I've only lived here for fifteen years!'
