At the BERGEN_FLORIDA weather station, which we use for Bergen, the warmest month is July (average high 19.6 °C) and the coldest February (average low 0.1 °C), averaged over 1991–2020. The wettest month is December (290 mm of rain). Across Norway, the quietest month for visitors in 2025 was January.
Bergen weather by month
Averages for 1991–2020 at the BERGEN_FLORIDA weather station (12 m above sea level), from the WMO climate normals, next to each month's share of Norway's tourist nights (Eurostat, 2025) in 2025. The shares are for the whole of Norway, not Bergen alone. These are long-term averages, not a forecast. A rainy day is one with at least 1 mm of rain.

Golden hour and sea temperature
Evening golden hour is our calculation for the 15th of each month of 2026: the time the sun takes to go from 6° above to 4° below the horizon (there is no official definition). The sea figure is the 1991–2020 average sea surface temperature at the open-sea point nearest the weather station (NOAA OISST).
| Month | Evening golden hour (15th) | Sea surface |
|---|---|---|
| January | 2 h 12 min | 6.6 °C |
| February | 1 h 33 min | 5.6 °C |
| March | 1 h 22 min | 5.2 °C |
| April | 1 h 26 min | 6.2 °C |
| May | 1 h 47 min | 8.5 °C |
| June | 2 h 16 min | 11.8 °C |
| July | 1 h 59 min | 14.6 °C |
| August | 1 h 32 min | 15.9 °C |
| September | 1 h 21 min | 14.5 °C |
| October | 1 h 26 min | 12.1 °C |
| November | 1 h 53 min | 9.8 °C |
| December | 2 h 55 min | 7.9 °C |
The quietest and busiest months
In 2025, January was Norway's quietest month (4.9% of the year's tourist nights): at Bergen's station that month averages a high of 4.7 °C, a low of 0.6 °C and 256 mm of rain. July was the busiest (18.2%): average high 19.6 °C, average low 12.4 °C, 158 mm of rain. The visitor figures are for the whole country, and they do not show that the weather makes a month busier or quieter, so we do not say it does.
What these figures are
One weather station stands for Bergen; places nearby can differ, especially by height or distance from the sea. For the rest of Norway, including regions and holidays, see our Norway page; for other places, the weather by city list and golden hour by place.
Key takeaways
- Warmest month: July (average high 19.6 °C); coldest: February (average low 0.1 °C).
- Wettest month: December (290 mm); driest: May (108 mm).
- In 2025, January was Norway's quietest month for visitors and July the busiest.
