What January feels like

Locals call the November-to-February stretch the Big Dark, and January sits square in the middle of it. Nobody here owns an umbrella; a hooded shell and shoes you do not mind soaking are the entire uniform. The consolation is that it almost never gets properly cold — the freezes arrive in short snaps and move on.

Rain arrives about 13 days of the month, so keep one flexible day in your plans. about 7 nights dip below freezing.
