The climate of Miami is of a tropical monsoon type (Köppen climate classification Am); summers are hot, humid, and wet, while winters are warm and typically dry. The warm Gulf Stream current, along with the North Atlantic drift, significantly influences its climate. Its location near the Tropic of Cancer provides an exception to cold waves that usually sweep a considerable portion of the United States.

It is sunny all year round with plenty of daylight hours barring patches of stormy and rainy weather during the summer. High temperatures reach up to an average of 90°F (32.2°C) during peak summer; low temperatures rarely drop below the average of 60°F (15.6°C) during winter. Occasional cold fronts account for slightly low temperatures and rain during the winter.

The prominently wet season from May to October experiences the majority of the 61.9" (1572.3mm) of yearly rainfall. Abundant rainfall occurs mainly during short spells of heavy showers and thunderstorms during this period, as the sun hides briefly for these intervals.
March to May is the best time to visit Miami, although the entire period from December to May hosts pleasantly mild weather with a few exceptions. The winter, though warm and pleasant, maybe a host to cold winds and rain on occasions. While the spring months are comparatively less warm than the summer, they are also distinctly less muggy and are a great time to visit Miami and the Keys and Everglades around it. Spring is also one of the better periods for swimming in the ocean with the average sea temperatures in a comfortable range of 75°F (23.9°C) to 77°F (25°C).

The wet season is a time to avoid Miami, during which the period from August to October is the worst time for a visit. It is statistically more prone to hurricanes during this time, and the weather can change quite suddenly. The heat is intense during summer; the mercury column is in sight of the 90°F (32.2°C) and along with the sticky weather, makes it uncomfortable for going around the city. Approximately 70% of the annual rainfall occurs during the wet season, and it is a threat to a concisely planned vacation.
