What to ExpectPart of the lure of the Florida Keys is that it is the only Caribbean-like getaway that you can drive to. Another plus is the wide variety of diving available, ranging from shallow sites like the Christ of the Abyss statue near Key Largo to more challenging explorations of deeper wrecks along Shipwreck Trail. Water temperatures range from 74 degrees in the winter when choppy conditions are more frequent to 86 degrees in the summer when seas are typically flat. Air temps are mild but can dip into the 50s in the winter. Vis averages 40 to 70 feet.Tourism and TravelFlorida Visitors Office888-7-FLA-USA Hotels, Resorts and OperatorsAbyss Dive Center800-457-0134 American Diving Headquarters305-451-0037 Amy Slate's Amoray Dive Resort800-426-6729 Bud N' Mary Dive Center800-742-7945 or 305-664-2211 Captain Hook's Dive Center800-278-4665 or 305-743-2444 Captain Slate's Atlantis Dive Center Captain's Corner Dive Center305-296-8865 Caribbean Watersports800-223-6728 or 305-852-4707 Conch Republic Divers800-274-3483 Coral Reef Park Co.305-451-6322 Discount Divers305-743-2400 Divers City, USA800-649-4659 or 305-451-4554 Dixie Divers of Key Largo800-FLA-DIVE or 305-453-9588 Dolphin Cove Research Center305-451-4060 Fantasea Divers800-223-4563 or 305-743-5422 Florida Keys Dive Center Florida Keys Reef Divers305-515-2750 Holiday Isle Dive Center800-327-7070 or 305-664-3483 Horizon Divers800-984-DIVE or 305-453-3535 It's A Dive/Marriott Key Largo800-809-9881 Kelly's On the Bay/Aqua-Nut Divers800-226-0415 or 305-451-1622 Key West Diving Society305-292-3221 Lady Cyana Divers800-221-8717 or 305-664-8717 Looe Key Reef Resort & Dive Center305-872-2215 Ocean Divers Paradise Charters of Key Largo800-872-1114 Paradise Divers305-872-1114 Quiescence Diving Services305-451-2440 Rainbow Reef Dive Center305-664-4600 Sea Dwellers Dive Center305-451-3640 Sea Raven Dive Charters305-852-9915 Sea-Clusive Charters305-744-9928 Silent World Dive Center800-966-3483 Southpoint Divers800-891-3483 or 305-296-6888 Strike Zone Charters305-872-9863 Subtropic Dive Center305-296-9914 Tavernier Dive Center305-852-4007 Underseas800-446-5663 Upper Keys Dive & Sport Center305-853-0526
