Key West has a tropical savanna climate and ranks among the warmest cities in the United States. At Key West International Airport, the 1991-2020 reference averages range from a daily high of 76°F (24°C) in Jan to 91°F (33°C) in Aug. Monthly precipitation averages sum to 40.4 inches (1027 mm) per year.
The dry season (November-April) brings steady trade winds, low humidity, and near-constant sunshine. The wet season runs May through October with muggy heat and passing showers and thunderstorms. Hurricane season spans June through November, and as a low-lying island surrounded by warm water, Key West is exposed to storms approaching from the Atlantic, Caribbean, or Gulf. Winter cold fronts occasionally reach the Keys, dropping temperatures into the 60s.
Key West's official climate record has a lowest temperature of 41°F, observed on January 12, 1886, and January 13, 1981. The surrounding ocean helps moderate winter cold on the island.
Local Planning Guide
August through October is Key West's most critical window, when peak hurricane risk overlaps with the heaviest wet-season rainfall.
On a small island surrounded by warm water, marine warnings, waterspout-prone storm cells, and tropical alerts matter as much as standard land-based forecasts.
