What state has the most overcast days each year?
This is a difficult question to answer because of the large area that some states cover. The amount of cloudiness is also seasonally dependent. An examination of a very broad based climatological analysis of the contiguous (lower 48) states shows that during the fall/winter season (December through February), the state of Washington has the least amount of possible sunshine, hence the most clouds. For the spring/summer season (June through August), that honor goes to the state of Maine, followed closely by Vermont and New Hampshire.
