And it’s not just the number of overcast days that is a problem. Bellingham is very far north—enough so you get significant swings in day length between summer and winter—that is great in the summer, it is still broad daylight out at 11pm at night—but winter days are really short. Sunset is around 4:30, or earlier, from mid-Nov to mid-Jan. The sun has gone down before you get off work.
