An independent guide to diving the walls of the Turks and Caicos Islands.
Plan a trip
Everything to sort out before you go: when to dive, what the water is like, which island to base on, how to get between islands, and the safety details that matter on remote walls.
The diving is good all year. Each season has its own trade-offs.
Peak travel season, with dry weather and the coolest water of the year, around the high 70s °F (about 25 °C). Humpback whales pass through the Turks Island Passage from roughly January to April. Winter cold fronts can bring wind and swell to north-facing sites.
Water warming into the low 80s °F (about 27–28 °C), lighter winds on many days and fewer visitors. Often an excellent time for calm conditions and long dives. The hurricane season officially begins on June 1.
The warmest water, in the mid 80s °F (about 29 °C), and the quietest islands. This is also the peak of the hurricane season, so buy travel insurance that covers storms and keep your plans flexible.
Water temperatures in the Turks and Caicos range from the high 70s °F in winter to the mid 80s °F in late summer. Many divers are comfortable in a 3 mm full wetsuit most of the year; people who feel the cold, or who plan several dives a day in winter, often prefer a 5 mm suit or a hooded vest. A rash guard or skin suit is enough for snorkelling. Visibility is often very good, commonly 60 to 100 feet or more on the walls.
Your base decides the kind of trip you have. Providenciales has the international airport, the most operators and accommodation, and day trips to West Caicos and French Cay. Grand Turk has the wall just off the beach and very short boat rides. Salt Cay is tiny and quiet, with winter whales and a historic wreck site. South Caicos is remote and lightly dived. Many divers split a trip between Provo and one of the smaller islands.
Most international flights arrive at Providenciales International Airport, with direct services from several cities in North America and connections from Europe. Grand Turk, Salt Cay and South Caicos all have small airports served by domestic flights, and a ferry links Grand Turk and Salt Cay on some days. Inter-island schedules are limited and change, so book connections early and check them again before you travel.
The territory uses the US dollar, and English is the official language. Visitors from many countries need a valid passport and a return or onward ticket; check the current entry rules for your nationality before you book.
Wall diving is easy in good conditions, but the bottom is far below you, and some islands are a long way from medical help. Plan with that in mind:
Many of the best sites are in marine national parks. Inside them, taking or disturbing marine life is prohibited. Don't touch or stand on coral, keep fins clear of the reef, don't feed or chase animals, and follow your operator's briefing on whales and turtles. Spearfishing equipment is not something to bring. Choose a reef-safe sunscreen and wear a rash guard to reduce the amount you need.
With your season and island chosen, compare operators on boat size, group size, the sites they actually visit and how they handle safety. Our guide to choosing among Turks and Caicos dive shops lists the questions to ask before you book.
There is no single best month. April to July often combines warm water, calm seas and fewer visitors; January to April adds humpback whale season; August to November has the warmest water but falls in the peak of the hurricane season.
A 3 mm full wetsuit suits most divers most of the year. People who feel the cold, or who dive several times a day in winter, often prefer 5 mm.
A common guideline is at least 12 hours after a single no-decompression dive and 18 hours after repeat dives or multi-day diving. Inter-island flights count.
