The Caribbean gets rough in winter. North swells push through the Bahamas from December through March, turning open beaches into wave-battered stretches. But crescent bays protected by offshore cays and headlands stay glass-calm, their turquoise shallows untouched by the chop. Five of them keep their water flat when the rest of the islands turn restless.
Fernandez Bay, Cat Island, Bahamas: where 1-mile crescents stay glass-calm
Fernandez Bay curves for a mile along Cat Island’s western shore, facing the Exuma Sound instead of the Atlantic. The difference matters. While the eastern coast takes the full force of winter swells, this crescent sits protected by low green hills and offshore cays. The water stays turquoise and calm, even when February winds pick up.
New Bight Airport sits 5 minutes away. Maker’s Air flies direct from Fort Lauderdale Executive in an hour, around $300-500 round-trip. The island stretches 46 miles long but narrows to 1 mile wide in spots. Population hovers around 1,500, with maybe 200 in New Bight. Fernandez Bay Village spreads across 50 acres with 18 beachfront cottages. Rooms include meals. No casinos, no high-rises, no crowds.
What makes the water stay calm
Southeast winds dominate December through March. The cays offshore break the fetch, and the Exuma Sound lacks the Atlantic’s relentless push. Mornings bring the flattest conditions, before afternoon breezes ripple the surface. Water temperature holds at 76-80°F. Visibility reaches crystal-clear depths, though exact measurements stay unrecorded. The bay faces southwest, so sunrise lights up the hills behind you while the water stays shadowed until mid-morning.
The highest point in the Bahamas sits nearby
Mt. Alvernia rises 206 feet, claiming the national elevation record. Father Jerome built The Hermitage monastery at the summit in 1939, a stone structure reached by steep paths and low arches. The hike takes 20 minutes from the bay. Views stretch across both coasts. The trail involves ducking and scrambling, but the payoff spans the entire island. For more protected Caribbean options, this 12-acre island costs $10 to enter where coral reefs sit steps from shore.
Half Moon Bay, Antigua: reef-protected postcard where resorts stay small
Half Moon Bay stretches along Antigua’s southeastern coast, a crescent of white sand backed by low vegetation. A fringing reef runs 50 yards offshore, breaking the winter swells before they reach the beach. The water grades from pale turquoise in the shallows to deep blue beyond the reef. December through March brings calm mornings and light afternoon winds.
VC Bird International Airport serves Antigua with direct flights from New York, Miami, and Atlanta. Drive times to Half Moon Bay vary by route, but the island measures 14 miles across at its widest. No mega-resorts crowd the bay. Small guesthouses and beachfront rentals dominate, though specific 2026 pricing remains unconfirmed. The reef supports snorkeling, with tropical fish and coral heads visible in clear water.
Devil’s Bridge and windward coast hikes
The windward side of Antigua faces the Atlantic, where waves crash into limestone formations. Devil’s Bridge sits a short drive from Half Moon Bay, a natural arch carved by centuries of surf. The hike involves walking along iron-shore cliffs, with blowholes shooting spray during high swells. It contrasts sharply with the calm bay, showing both sides of the island in one morning.
Trunk Bay, St. John, USVI: national park beach with underwater trail
Trunk Bay sits within Virgin Islands National Park, protected by federal designation since 1956. A marked underwater snorkel trail runs parallel to the beach, with plaques identifying coral species and reef fish. The bay faces northwest, sheltered from winter swells by surrounding hills and offshore cays. Water stays calm December through March, with visibility reaching 50-80 feet on clear days.
Ferries run from Red Hook on St. Thomas, a 20-minute crossing. Cruz Bay serves as the main town on St. John, with lodging options from guesthouses to vacation rentals. Specific 2026 rates for Trunk Bay’s day-use fee remain unverified, but past years charged around $20. The park protects 70% of St. John, keeping development minimal. For similar calm water experiences, 9 Kauai beaches where coral reefs keep turquoise water calm all winter offer Pacific alternatives.
Reef Bay Trail to petroglyphs
The Reef Bay Trail descends from Centerline Road to the southern coast, passing through tropical forest and past Taino petroglyphs carved into boulders. The hike covers 2.2 miles downhill, with a steep return climb. Petroglyphs sit near a freshwater pool, shaded by trees. The trail offers a different side of St. John beyond the beaches, connecting cultural history to the island’s protected landscape.
Maho Bay, St. John, USVI: sea turtle breakfast spot in gin-clear shallows
Maho Bay sits on St. John’s northern shore, a crescent of sand with seagrass beds extending into shallow water. Green sea turtles graze the seagrass from dawn through mid-morning, often within 10 feet of shore. The bay stays calm December through March, protected by surrounding headlands. Zero development lines the beach. A small parking area and portable toilets mark the only infrastructure.
The drive from Cruz Bay takes 15 minutes along North Shore Road. Turtles appear most reliably between 7-9am, before afternoon winds pick up. Regulations require staying 6 feet back from the animals. Snorkel gear works better than masks alone, as the turtles move between shallow and deeper patches. Water temperature holds at 77-81°F in winter. For more Caribbean protected bays, Silk Cayes snorkeling brings sea turtles to turquoise sandbars 26 miles from Placencia.
Shoal Bay East, Anguilla: 2-mile white crescent where Anguillans keep time slow
Shoal Bay East stretches 2 miles along Anguilla’s northeastern coast, a powder-white crescent facing the open Atlantic but protected by offshore reefs. The reefs break winter swells before they reach shore, keeping the water calm December through March. Turquoise shallows extend 50 yards out, grading to deeper blue beyond the reef line. No high-rises interrupt the beach. Small beachside shacks serve fresh lobster for $30-40.
Ferries run from Marigot on St. Martin, a 25-minute crossing for around $30 round-trip. The drive from the ferry terminal to Shoal Bay takes 20 minutes. Anguilla measures 16 miles long and 3 miles wide, with a population around 15,000. The island maintains a low-key vibe, with locals outnumbering tourists even in peak season. Beachfront villas rent for $250-500 per night, though specific 2026 availability varies. Shoal Bay Scuba operates from the east end, offering reef dives and snorkel trips.
Why Anguilla stays quiet
No casinos, no cruise ships, no international chains. The island built its tourism around small resorts and villa rentals, keeping density low. Locals fish the same waters their families have worked for generations. The pace stays unhurried. February brings the best pricing before spring break crowds arrive in March.
Your questions about Caribbean crescent bays answered
Which bay has the calmest water in February?
Fernandez Bay and Maho Bay both offer exceptional calm in February, protected by offshore features and facing away from prevailing swells. Fernandez Bay’s Exuma Sound location provides slightly more consistent flat water, while Maho Bay’s northern exposure can see light afternoon chop. Both stay swimmable all day.
Do I need a car to reach these bays?
Fernandez Bay sits 5 minutes from New Bight Airport by taxi. Trunk Bay and Maho Bay require a car or taxi from Cruz Bay on St. John. Half Moon Bay needs a rental car from Antigua’s airport. Shoal Bay East requires a car from Anguilla’s ferry terminal. Only St. John offers reliable taxi service to beaches.
How do these compare to Turks and Caicos?
Grace Bay in Turks and Caicos sees heavier crowds and higher prices, with rooms starting at $500-1000 per night December through March. The five bays listed here offer similar turquoise calm at 30-50% lower costs, with fewer tourists. Grace Bay’s sand rates slightly finer, but the water clarity matches. For budget-conscious travelers seeking similar beauty, better than Maldives where resorts cost $250 and Andaman keeps turquoise for $12 provides another alternative.
Morning light hits Fernandez Bay around 7am in February. The water stays flat, reflecting the green hills behind the beach. A few footprints mark the sand from early walkers. The rest of the bay sits empty, waiting for the day to start.
