How many days a year does it rain in Bergen?
Rainy days, yearly totals and the reasons behind Bergen's wet climate.
Short answer
On average it rains on 200 days a year in Bergen, according to Bergen Municipality, which is more than half of all days. MET data from the Florida station show between 171 and 234 days with more than 1 mm of precipitation a year in 2019–2025. The 1991–2020 normal is 2,495 mm a year, about three times Oslo's.
Why
- Bergen Municipality says the city's position between seven mountains makes it especially exposed to rain.
- The prevailing airflow over the region comes from the west or south-west, and most precipitation arrives with fronts and showers from the west (Store norske leksikon).
- In the 1991–2020 normals for Bergen (Florida), December is the wettest month with 290 mm and May the driest with 109 mm.
Details
Even Bergen's driest month gets more than Oslo's wettest: the May normal of 109 mm is above Oslo's August normal of 103 mm. From September to December the normals are 248–290 mm a month. The sources checked here do not rank European cities by rainfall, so the claim that Bergen is Europe's rainiest city cannot be confirmed; Store norske leksikon notes that parts of the former Hordaland county about 50 km from the coast get over 3,000 mm a year.
Tip
Bring a waterproof jacket and shoes in any season, and check the hour-by-hour forecast on yr.no to plan outdoor time around the rain.
What may differ
Rainfall varies a lot from year to year: Bergen had 2,806 mm in 2024 and 2,415 mm in 2025, according to the municipality's figures from MET.
Common misconception
It rains every single day in Bergen.
What actually happens
Not quite. Bergen Municipality puts the average at 200 rainy days a year, and in 2025 the Florida station recorded 201 days with more than 1 mm of precipitation.
