In the winter, sure. During the summer it's actually pretty dry and at least in Portland it's not unheard of to go a month or two with no measurable precip. As long as evaporation is taking place then evaporative cooling should still function. Will it be more efficient with low humidity? Yes.
As it stands now the outdoor air temp is 22*C with an RH is 44%
