Quillayute River
It should come as no surprise that the most humid place in the U.S. also has the second most days of precipitation in the nation (and the most in the contiguous 48 states): Quillayute, Wash. With an average humidity of 83.0 (and 210 days of precipitation to go along with it), life may seem hotter on Washington’s Olympic Peninsula. But even if it doesn’t get hot, it sure does get humid.
