Key West Weather in December
United States · early winter in Northern Hemisphere / early summer in Southern Hemisphere
Key West at America's southernmost point has a true tropical climate — the only place in the continental US where it genuinely never gets cold. Surrounded by water on all sides, temperatures are moderated dramatically with winters in the 70s and summers rarely above 92°F. Hurricane risk is severe, and the Florida Straits can generate massive swells.
Holiday season. Many cities decorate beautifully. Book ahead for December travel.
