kaamos

/ˈkɑːmos/

The polar night. Not "dark winter", and the distinction is one Finns will correct you on

Quick answer

Kaamos is the polar night: the stretch of winter inside the Arctic Circle when the sun never clears the horizon.

  • Helsinki does not have one. Whether you get kaamos at all depends entirely on your latitude.
  • In Utsjoki, Finland's northernmost municipality, it runs from late November to mid-January - around fifty days.
  • What southern Finland gets instead is short, dark days, and that has its own word: pimeä.

What kaamos is

The word is borrowed from Northern Sámi skábma, and it is an astronomical fact before it is a feeling. Above the Arctic Circle the sun stays below the horizon for a stretch of the winter, and the length of that stretch grows the further north you go.

It is not black. There is a blue twilight for a few hours around the middle of the day, and snow returns most of what light there is, which is why people who have been there describe it as blue rather than dark.

How Finns actually use kaamos

Literally, about the north. Kaamos alkoi - the polar night has begun - is a news sentence, and Yle reports it each year as the sun sets in Utsjoki for the last time until January.

Loosely, about the mood of the dark months anywhere in the country - kaamosmasennus is seasonal depression, and kaamosväsymys the tiredness of it. That extended use is normal, and it is also where the precision goes.

The related words are worth having: pimeä is dark or darkness generally, and it is what a Helsinki winter actually is. Ruska is the autumn colour that comes before it. Kaamosvalo is the blue light of the polar night itself.

kaamos in a sentence

The mistake everyone makes with kaamos

Treating kaamos as a synonym for winter darkness. Helsinki in December has around six hours between sunrise and sunset. That is dark and it is not kaamos.

Assuming it means total blackness for two months. There is real twilight in the middle of the day, and in snow it is bright enough to walk in.
