Turks and Caicos Islands

The Turks and Caicos Islands sit at the southeastern end of the Bahamas chain, separated from the main Bahamas archipelago by the deep Turks Island Passage — a 2,200 m trench that channels Atlantic water between the two island groups. The tidal regime is mixed semidiurnal with a spring range of 0.4–0.6 m, placing TCI firmly in the microtidal bracket. Weather effects — surge from hurricanes and tropical storms, wind-driven setup from trade wind events — routinely dwarf the astronomical signal from June through November. The two island groups are geographically and administratively distinct: the Caicos Islands to the west (Providenciales, North Caicos, Middle Caicos, South Caicos) face the shallow Caicos Bank, while the Turks Islands to the east (Grand Turk, Salt Cay) sit on a narrow shelf above the Turks Island Passage. Grace Bay on Providenciales is frequently ranked among the world's top beaches — a 12-kilometre arc of white silica sand behind a barrier reef that keeps the inshore water calm regardless of ocean swell. Grand Turk's western wall is one of the Caribbean's signature dive sites, dropping from 9 m at the reef top to 2,100 m within 300 m of shore. Salt Cay, the southernmost and smallest of the populated islands, preserves the salt-raking infrastructure of the 18th and 19th centuries when Bermudan merchants harvested salt from its crystallisation ponds for export to the American colonies.
