I know what you mean. It gets downright depressing at times. Just grin and bear it. Pretend you're Gene Kelly and start singing and dancing in the rain. Other than crappy visibility and a slight regen penalty, there isn't much downside to just going out in it.

Speaking of crappy visibility, this sure is a dim game. Several of the biomes are dark and, I'd swear, half the time the nights are twice as long as the days. I believe I'm getting lots of new wrinkles on my face for all the squinting I do playing this game.

PS - My brother lived in Seattle and had a t-shirt that had some ducks with little umbrellas and said, "Seattle Rain Festival, January 1st through December 31st"
