West Trinidad

Trinidad's tidal regime is shaped by geography unlike anywhere else in the Caribbean. The island sits on the South American continental shelf, less than 12 km from Venezuela at its closest point, and is separated from the mainland by two narrow straits: Dragon's Mouth (Bocas del Dragón) to the north and Serpent's Mouth (Boca de la Serpiente) to the south. The Gulf of Paria, enclosed between Trinidad's west coast and Venezuela, functions as a semi-enclosed basin where tidal exchange is throttled by these two strait systems. The result is a mixed semidiurnal tide with pronounced diurnal inequality — the two daily highs differ meaningfully in height, and the two lows are often dramatically unequal. Spring tidal range in the Gulf of Paria runs 0.5–0.8 m, noticeably larger than the open Caribbean norm. The north coast of Trinidad faces the Caribbean Sea directly through Dragon's Mouth and receives trade-wind swell from the northeast November through April. Port of Spain on the northwest coast is the commercial and political capital, with a working deep-water port, a ferry terminal to Tobago, and a renovated waterfront at the base of the Northern Range. Chaguaramas, 15 km west of Port of Spain, is the island's yachting hub — a natural bay backed by low hills, with government and private marinas serving the regional sailing circuit. Both locations sit within the Gulf of Paria's sheltered water; the west coast is protected from ocean swell by the gulf's enclosed geometry.
