Key West Weather in May
United States · late spring in Northern 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.
One of the most popular travel months worldwide for good reason.
