During my years in the U.S., I’ve been asked more than one variation of the question “Is it always cold?” in Finland. (The short answer, of course, is No; the long answer is It depends on your definition, and when and where in Finland you are. It CAN be cold, but “always”, no.)
What southern people don’t usually realize is that it’s not the winter cold but the long dark that affects you most. (Of course, as a counterpoint, we do also have the magical light summer nights.)
Besides, the dark isn’t all bad. Away from light pollution there is the Milky Way on clear nights, and the further north you go, the higher are your chances of seeing northern lights. The latter can range from faint whisps to quite a light show.
For your potential worldbuilding inspiration, here is a small selection of Flickr photos roughly from around where I grew up, including travel destinations in the north.
For me, and indeed most other Finns, winter starts some time in November to December, depending on the temperatures each year. And even though technically I didn’t grow up with the polar night (when the sun doesn’t rise above the horizon at all), it was quite dark especially before the snow fell—which is exactly why getting snow on the ground was such a relief.
