Grand Cayman Island, along with Little Cayman and Cayman Brac, together compose the Cayman Islands. The islands are located in the Caribbean, 90 miles south of Cuba. Grand Cayman is the largest of the three islands, running approximately 22 miles long from East to West, and 8 miles from North to South.
The Caymans lie in a tropical climate, with average temperatures ranging from 24-27 Degrees Celsius throughout the year. Water temperature typically mimics the average air temperature. Rainfall in the islands is moderate from mid May to August, with heavy rains occurring from September to October. January through May is the dry season.
Grand Cayman is surrounded by barrier reefs, which serve to protect the island from trade wind driven waves. In some areas of the island, the growth of mangroves also acts as a buffer. Salt and brackish ponds can be found in the island's interior.
