Every winter from December to March, great hammerhead sharks gather around the Bimini Islands in large numbers, curiously approaching dives.
The Gulf Stream runs past Bimini, bringing in a host of big fish to the pristine, sloping wall of Tuna Alley, so named for its frequent schools of tuna.
Each year, divers cage dive with bull sharks for charity. This event is managed by the Bimini Big Game Club and proceeds go to shark conservation.
The Bahamas enjoys a hot and sunny climate year-round, although June to October is considered the rainy season. It usually rains once a day, every day but only for short periods of time.
June to October is also considered hurricane season. If you are planning a trip to the Bahamas during these months, consider taking out travelers insurance on the off chance a hurricane forms during your vacation.
Air temperatures during the summer months range from 75-91°F (24-33°C) while water temperatures are approximately 88°F (31°C).
If you enjoy getting the best deals and diving at uncrowded dive sites, book your trip from June to October. This is low season in Bimini. Besides the sometimes stormy weather and the number of sharks present, diving in the Bahamas changes little from month to month.
November to May is the dry season in the Bahamas. During these summer months, you can expect sunny, hot and mildly humid conditions.
Air temperatures during the winter months range from 65-77°F (18-25°C) while water temperatures are 75-80°F (24-27°C).
In addition to great topside conditions, November to May is also the best time for shark diving. You’ll find hammerhead sharks at Bimini from December to March. Bull sharks can be found during the same months.
However, November to May also represents high season for tourism in the Caribbean. So be sure to book early in order to get a good deal on accommodation and flights.
Many scuba divers who are attracted to Bimini come to see the sharks. During the winter and spring months, you’re likely to see hammerhead sharks, bull sharks, Caribbean reef sharks, silky sharks, oceanic whitetip sharks and the occasional tiger shark. Dolphins often show up to investigate both divers and their boats. And pilot whales, humpback whales and sperm whales can be seen when traveling to open ocean dive sites. Green turtles, hawksbill turtles, leatherback turtles and eagle rays swim along the current while seahorses, Bahama sea stars, queen conches and hordes of tropical fish hide amongst the colorful coral reefs.
