Key West Weather Radar Guide: Reading Local Storms
Radar is most useful when it answers a local question: whether rain is moving toward your neighborhood, whether storms are strengthening, and whether conditions near Key West need closer attention.
Local Radar Answer
Quick answer for Key West weather radar
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.
Local hazards to compare
- Hurricane and storm surge risk on a low-lying island
- Frequent waterspouts in the surrounding waters
- Rip currents and hazardous marine conditions
- Summer heat indices amplified by high humidity
When to watch more closely
August through October is Key West's most critical window, when peak hurricane risk overlaps with the heaviest wet-season rainfall.
Radar should show motion, not just color
A useful Key West weather radar app should make storm movement clear: where precipitation is now, which direction it is moving, and whether the strongest returns are approaching your saved places.

WeatherAI connects radar, hourly forecasts, local summaries, and weather alerts so radar becomes part of a planning workflow for commuting, travel, outdoor plans, and storm monitoring in Key West.

Local Weather Context for Key West
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.
