10 Wettest Cities In The United States

Rain is often a much sought-after weather event, but when it often occurs in great quantities over a short period, fatigue may be sure to follow. From thunderstorms to hurricanes, or just a heavy downpour, excessive rain can, like anything in overabundance, be troublesome. Across the United States, several cities experience higher than average rainfalls, uniquely shaping their local history and culture and how they cope with modern-day weather challenges. Here are the Top 10 Wettest Cities in the United States by the number of yearly rainy days:

1. Hilo, Hawaii - 211 rainy days/year

Located on the Big Island of Hawaii, Hilo records an average of 211 days a year with at least one millimeter of rain. This means that for just under 60% of the year, one can expect to experience some form of precipitation in this Pacific paradise. With its rainforest-like climate, hot, humid temperatures exist no matter the season, and in a span of 30 years, between 1980 and 2010, over 3,000 millimeters of rain were recorded each year. Interestingly, Hilo receives up to 30 times more rainfall than other communities on the Big Island due in part to its elevation.

2. Sitka, Alaska - 173 rainy days/year
