Diving in the Bahamas in December

Conditions in December

So, you're eyeing a dive trip to the Bahamas in December? Excellent choice, my friend! This is when the islands truly shine, escaping the summer heat and the tail-end of hurricane season. You can generally expect glorious weather, with average air temperatures hovering around 22-26°C (72-79°F). The occasional cold front might sweep through, bringing slightly cooler air and choppier seas for a day or two, but these are usually brief.

The water temperature is still very comfortable, typically around 24-26°C (75-79°F). While this is a little cooler than the peak summer months, it’s still warm enough for extended dives without feeling the chill. Visibility is usually stellar, a consistent 20-30 meters (65-100 feet) or more, thanks to the crystal-clear Bahamian waters and less planktonic activity than in warmer months. You'll often feel like you're diving in an oversized aquarium!

Currents around the Bahamas are generally mild to moderate, depending on the specific dive site and lunar cycle. Some drift dives can be exhilarating, but most sites offer a relaxed experience. December is also the official start of the "high season," meaning the weather is more predictable and stable, offering fantastic conditions for exploring the vibrant reefs and spectacular blue holes.

What you will see

December diving in the Bahamas is all about the big stuff, with an undeniable focus on the shark action this region is famous for. You'll be absolutely spoiled for choice with various shark species making regular appearances. Reef sharks – Caribbean, blacktip, and whitetip – are practically guaranteed on most dives, cruising gracefully along the reef edges. But what really gets the heart pumping are the iconic tiger sharks, often encountered around sites like Tiger Beach, and the majestic hammerheads, particularly aggregations of great hammerheads in the Bimini area as the cooler water temperatures start to entice them in from deeper waters.

Beyond the toothy grins, December still offers plenty of other pelagic thrills. Keep an eye out for curious lemon sharks, nurse sharks resting in crevices, and if you’re lucky, you might even spot oceanic whitetips in certain offshore locations. While mantas are less common than in some other dive destinations, eagle rays are a frequent and breathtaking sight, soaring through the water with their elegant wingbeats. You'll also encounter schooling barracuda, jacks, and snapper adding to the vibrant marine tapestry.

The reefs themselves are bursting with life. Expect to see colorful parrotfish, angelfish, grouper, grunts, and moray eels peeking out from their hideaways. While not a primary macro destination, keen-eyed divers can still discover interesting critters like nudibranchs, crabs, and shrimp tucked away amongst the corals. December is a prime time for those seeking consistent large animal encounters, making it an incredibly rewarding month for underwater photography and unforgettable interactions.

Top dive sites this month

When planning your December Bahamian dive adventure, a few locations really stand out. First up, without a doubt, is the renowned Tiger Beach near Grand Bahama. This shallow, sandy bottom offers unparalleled opportunities for close encounters with magnificent tiger sharks, often alongside lemon and reef sharks. The predictable nature of these interactions makes it a world-class shark diving destination, and conditions in December are typically calm and clear.

Next, you absolutely must consider Bimini, especially if great hammerheads are on your bucket list. As the water cools slightly in December, these incredible creatures begin to gather in the shallower waters around Bimini, providing incredible opportunities for observational dives. The famous “Runway” dive site is where many of these incredible encounters take place. For more general reef diving with a chance of pelagics, the walls of the Exumas Cays Land and Sea Park offer pristine coral gardens, swim-throughs, and a healthy population of reef sharks and other large fish, all protected within a national marine sanctuary.

Practical tips for your trip

For December diving in the Bahamas, a 3mm full wetsuit should be perfectly adequate for most divers, given the 24-26°C (75-79°F) water temperatures. If you tend to get cold easily, or if you plan on doing multiple dives a day, a 5mm suit or a 3mm with a vest might be a good idea, particularly towards the end of the month if a cold front rolls through. This month is fantastic for both beginner and advanced divers. The generally calm conditions and excellent visibility make it very welcoming for those just starting out, while the thrilling shark encounters cater perfectly to the seasoned diver looking for something truly epic.

December kicks off the high season, so liveaboard availability starts to tighten up. We highly recommend booking your Blue Rides liveaboard well in advance – ideally 6-12 months out – to secure your preferred dates and vessel. As for packing, bring your standard dive gear, reef-safe sunscreen, a good hat, sunglasses, and lightweight clothing for topside. Don't forget an underwater camera – you'll want to capture those incredible shark encounters! Be aware that some of the more famous shark feeding dives may have strict protocols, so always listen carefully to your dive guides. Enjoy your epic Bahamian adventure!
