What is the weather like in Finland in December?
Daylight, snow and temperatures in the south and north in December.
Short answer
December is the darkest month. Southern Finland gets about six hours of daylight on the shortest day, and in northern Lapland the sun does not rise at all. Lapland usually has snow and temperatures of -10 to -20 °C. On the south coast winter only begins in December, so Helsinki can be snowy or grey and wet around zero.
Why
- The Finnish Meteorological Institute says the shortest day in southern Finland is about six hours.
- FMI says polar night lasts up to 51 days in the northernmost corner of Finland.
- According to FMI, winter starts in December in the southwestern archipelago.

Snow is likely in Lapland in December, but in the south the first lasting snow can come only in January.
