Weather & Climate

Wherever you are right now, chances are the weather is better here in the Florida Keys…

Key West has a notably mild, tropical climate.  It is the only city in the lower 48 states that has never experienced frost and, although cold fronts in winter months are not uncommon, January averages 70°F with temperatures rarely dropping below 50°.  The summer months bring heat and humidity, average high for a summer day is 89°F, but the ocean breezes temper the heat and the waters are an ideal temperature for water sports and exploration. 

From November through April, rain is sparse, but by late May, the season's first thunder-showers begin.  Rarely do they last an entire day, and locals relish the quick cool off of a tropical rain.   The official hurricane season is from June 1- November 30.  Storms can affect the Atlantic and Gulf coasts of the United States as well as the Caribbean and the Bahamas.  Key West has been affected by a few storms, but being protected by Cuba and the Bahamas as well as our coral reef system, the little island fares rather well.  Traditionally, the highest potential for storms is between August 15 and October 15. However, the daily weather during this period tends to be some of the most ideal of the year for boating and exploring the reef.

Whatever the weather brings, there is always something to entertain you in the bustling island city.   For information on Key West weather throughout the year and current weather conditions visit the National Weather Service.
