December Scuba Diving |

Why Dive in December

December is an excellent time for a scuba diving holiday in Saint Barthélemy, usually known as St Barth. The island’s dry season is getting under way, bringing warm days, comfortable sea temperatures and generally good underwater visibility. It is a wonderful way to enjoy the Caribbean before the Christmas and New Year celebrations reach their busiest point.

Water temperatures are typically around 27°C, so most divers are comfortable in a light wetsuit. The sea can be calm, particularly in sheltered bays, although local conditions vary from day to day. With a qualified dive centre checking the forecast and choosing the right site, both newer divers and experienced visitors can enjoy the island’s underwater world.

Reefs and Dive Sites

Saint Barthélemy has a surprisingly varied coastline for a small island. Around the protected marine areas, divers can find coral gardens, rocky pinnacles, sandy patches and drop-offs where reef fish gather. Shallow sites are ideal for relaxed morning dives, while deeper locations offer more dramatic scenery for confident, properly qualified divers.

Look out for angelfish, parrotfish, wrasse and colourful damselfish moving through the coral. Turtles are occasional visitors, and rays may glide over the sand if you keep a respectful distance. Visibility can be particularly rewarding in December, giving you time to notice smaller details such as sea fans, sponges and tiny reef creatures hiding among the rocks.

Choosing a Dive Centre

Booking with a reputable local dive centre is the easiest way to make the most of your trip. Centres can arrange equipment hire, boat transfers, refresher sessions and guided dives, as well as matching sites to your experience and comfort in the water. If you have not dived recently, a short review of essential skills can make the holiday feel much more relaxed.

December is a popular month, especially around the festive period, so reserve spaces and equipment before travelling. Bring proof of certification, tell the instructor about your experience and mention any medical considerations in advance. A good briefing will cover the site, currents, depth, marine life and the best way to protect the reef while you explore it.

Making It a Complete Holiday

Saint Barthélemy is easy to enjoy above the surface as well. After a morning underwater, you can have lunch near the harbour, relax on a sandy beach or explore the island’s winding roads and viewpoints. Gustavia has stylish shops, restaurants and a lively waterfront, while quieter corners provide space to slow down and enjoy the scenery.

Pack reef-safe sun cream, a reusable water bottle and a light cover-up for time on the boat. Allow yourself a sensible interval between your final dive and flying, following current diving guidance. With warm water, professional local operators and plenty to do between dives, a December scuba holiday in Saint Barthélemy offers an appealing mix of adventure and easy Caribbean living.
