Miami Beach Weather & Climate

South Florida, in the Miami Beach, Key Biscayne, Coral Gables area, has the only sub-tropic climate in the United States, other than Hawaii. This region is exposed to daytime onshore breezes and enjoys comfortable temperatures during most of the year. Although the temperature is relatively moderate, the combination of the temperature and high humidity can be uncomfortable from May through September. However, cooling ocean breezes help to modify the climate. In fact, Miami actually has fewer hot days each summer than does the northern part of the state. In wintertime, it is one of the warmest places in the U.S. mainland, with sunny days and balmy nights. Most rain falls in summer, with frequent but brief, heavy thunderstorms. Hurricane season is generally August through October, with most occurring in September.
