March Scuba Diving |

Why Dive in March?

March is an excellent time for a scuba diving holiday in the United States Virgin Islands. The dry season usually brings warm sunshine, comfortable temperatures and good visibility beneath the surface, making it easier to appreciate the reefs, wrecks and marine life around St Thomas, St John and St Croix.

Water temperatures are generally pleasant enough for a lightweight wetsuit, while the calmer conditions can make boat trips enjoyable for both experienced divers and those returning to the sport. Above the water, there is plenty of time to relax on a beach, explore historic streets or enjoy a sunset after a day in the sea.

Reefs Around St Thomas

St Thomas is a convenient base for exploring a variety of dive sites, with operators offering trips for different experience levels. You may drift over coral gardens filled with angelfish and parrotfish, investigate rocky ledges or descend beside walls where the blue water seems to disappear into the distance.

Some sites are close to the island, which is useful if you prefer shorter boat journeys or want to combine diving with other activities. Local dive centres can advise on the best locations for the day, taking account of weather, currents and your experience.

Marine Life at St John

Much of St John is protected as part of the Virgin Islands National Park, and its surrounding waters offer some of the Caribbean’s most appealing shallow and intermediate dives. Coral reefs shelter schools of small fish, while turtles are a regular highlight for patient divers exploring calmly and respectfully.

The island’s clear water is also well suited to snorkelling, so a holiday here can work brilliantly for couples or families with mixed interests. After a morning beneath the waves, you can spend the afternoon on a quiet beach or follow a scenic trail through the green hills.

Wrecks and Walls at St Croix

St Croix offers a different diving experience, with a reputation for dramatic walls, reefs and accessible wreck sites. The Frederiksted Pier is particularly popular for shore diving, where divers can often spot seahorses, octopus and colourful reef fish among the underwater structures.

Experienced divers may enjoy deeper sites and the island’s striking drop-offs, while beginners can find calm locations with professional instruction. March is a good month to book ahead, especially if you have a particular course, boat trip or shore dive in mind.

Planning Your Dive Holiday

Choose a reputable, fully insured dive centre and check what is included in the price, such as equipment hire, transfers and marine park fees. If you have not dived recently, a refresher session is a sensible way to regain confidence before joining a boat trip.

Allow time between your final dive and flying, and remember to bring certification details, sun protection and a rash vest. With warm March weather, welcoming island communities and rewarding underwater scenery, the United States Virgin Islands make an unforgettable choice for a Caribbean scuba diving holiday.
