Florida Keys Weather

Although the Florida Keys have a tropical climate, temperatures never become unbearably high or unpleasantly cool, because of the cooling influence of the ocean. Summers are sunny and humid, with rain occurring mainly from late May in the form of thunderstorms, which last through to the Atlantic hurricane season. The Keys are at risk in the hurricane belt, the highest potential period for storms hitting being between mid-August and mid-October. Winters in the Keys are mild, sunny, frost free and clear.
