The fog season is a season of fog that occurs in some places, because of special meteorological and topographical characteristics, after a rainy period. The fog season is usually based in the cooler months (late autumn, winter and early spring). It is not generally true that fog season in a given area is during Fall or Winter (the cooler months); for example, the Japanese coast of the Pacific Ocean has a dense fog season from May to August. The June Gloom, a cloudy and foggy phenomena, experienced in the southern coast of California occurs in late spring and early summer (May and June).
