Climate

Ours is a subtropical climate. Temperatures range from the mid-50s to mid-80s. April and May are often idyllic. There are essentially two seasons: The winter season (December-March), which can be windy with rough seas, and the tropical storm season (June-November) during which Dry Tortugas experiences both hot, humid weather and calm seas or severe weather events. Due to our ever-changing weather patterns, an accurate weather forecast is recommended before your visit.
