Matanzas

Matanzas province extends east of La Habana along the Cuban north coast, taking in the Bay of Matanzas, the long sandy spit of the Hicacos peninsula at Varadero, and the Zapata wetland that dominates the southern coast. The northern Atlantic shore here is exposed to Atlantic swell wrapping in from the northeast, with a continental shelf that narrows quickly into deep water; the southern Caribbean coast at Zapata is sheltered, shallow and dominated by mangrove. The astronomical tide is mixed semidiurnal and modest. Mean range along the north coast runs roughly 30 to 50 cm, slightly larger than the inner Bahía de la Habana figure because the Hicacos peninsula projects northeast into open Atlantic water and picks up a fuller tidal signal than the harbour reach. Two unequal highs and two unequal lows each day, with the diurnal inequality producing one strong high and one weak high in most lunar phases. Wind, swell and the Florida Current dominate water-level variation outside the predicted range; winter cold fronts (frentes fríos) push elevated water along the Atlantic-facing beaches, while summer easterly trade-wind setup is the more common driver during the warm season. The authoritative tidal reference for Cuban waters is the Instituto Cubano de Hidrografía (GEOCUBA). NOAA gauges at Key West and the Florida Keys provide a useful regional cross-reference for the Florida Straits and Atlantic-side Cuba tidal regime. The Matanzas Atlantic coast holds Varadero's twenty-kilometre beach along Hicacos, the Saturno cave system inland of the resort strip, the Punta Hicacos lighthouse at the northeastern tip, and the colonial harbour and fortifications around Matanzas city itself at the head of the bay. Shore anglers, snorkellers, paddlers and beach-walkers along Hicacos plan around swell, wind and the front cycle as much as around the small astronomical tide.
