Key West Weather in August

United States · late summer 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.

Hot in many cities. Beach and outdoor destinations are at their peak.
