Havana tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

Marine-conditions data not available for this station. Wind, swell and water temperature ride along with Open-Meteo Marine; gauge-only stations (e.g. UK EA Flood) publish water level only.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are America/Havana local. Folk tradition, not a scientific forecast.

Havana faces the Florida Straits from the northern coast of Cuba, where the limestone shelf drops sharply into deep water and the Gulf Stream runs eastward only a few kilometres offshore. The tide here is mixed semidiurnal and genuinely small. Mean astronomical range inside Bahía de la Habana, the bottle-shaped harbour entered through the narrow channel between Castillo del Morro on the eastern headland and the Castillo de la Punta on the western, runs roughly 25 to 40 cm, with two unequal highs and two unequal lows each day. The diurnal inequality is real: most lunar phases produce one stronger high and one weaker high, with a corresponding pair of lows of different magnitude. That is microtidal by any conventional measure, and it places Havana in the same practical category as the inner Baltic — the predicted high and low describe a small water-level signal that other forces routinely exceed. The dominant non-astronomical driver is weather. Winter cold fronts (frentes fríos) sweeping down across the Gulf of Mexico arrive at the Cuban north coast as sustained northerlies that push water against the shore; during these events the wave overtopping along the Malecón seawall, from the Castillo de la Punta west past the Hotel Nacional and the Vedado coast to the mouth of the Almendares river, is the visible signature, and the elevated water level beneath the spray is real. Atmospheric pressure variation and the meander of the Florida Current contribute additional centimetres on either side of the predicted level. The Florida Current speeds and slows on a multi-day cycle, and a slower current slope offshore corresponds to a higher water level along the Cuban shore by several centimetres — small in absolute terms, but a meaningful fraction of the astronomical range. Shore anglers casting from the Malecón work the rocky shelf for jack, snapper and the occasional barracuda; they read the swell and the front forecast far more than the tide table. Paddlers launching from the Marina Hemingway west of the city or from the Bahía entrance navigate around vessel traffic and wind rather than tide state, since the current at the harbour mouth is driven by the bay-to-strait water exchange and dominated by wind setup. Beach-walkers and families heading east to Playas del Este — Santa María del Mar, Boca Ciega and Guanabo — find a wider sandy regime than the rocky urban coast offers, with gentle slope and moderate Atlantic exposure; the small tide range means the visible beach width changes only modestly between high and low, but the slope is shallow enough that the water line still moves several metres on a spring low. Snorkellers head east to the patch reefs at Playa Jibacoa, where the inshore reef ledge holds visibility windows on calm days; the slack period either side of the predicted change of tide aligns with the clearest water. Photographers on the Malecón at sunset plan around the front cycle and the swell forecast for the dramatic overtopping shots; the tide itself is rarely the deciding factor, but the early-morning low does pull the water back from the Castillo del Morro rocks for a tighter foreground if the swell is gentle. The Vedado coast and the rocky shelf at La Puntilla, just east of the Hotel Nacional, are popular swim entry points in summer; the small tide means the access regime is similar at high and low, but the swell forecast determines whether the entry is comfortable or rough. The authoritative tidal reference for Cuban waters is the Instituto Cubano de Hidrografía (GEOCUBA), which publishes harmonic predictions for the principal Cuban ports including La Habana. NOAA tide stations in the Florida Keys, particularly Key West, provide a useful regional cross-reference once the local offset is applied. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. For a coast with a tide range this small, the model's typical accuracy ceiling — plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — is a meaningful fraction of, and in some hours exceeds, the actual astronomical signal. Treat the predicted highs and lows as approximate. For activity-critical timing, weight GEOCUBA's authoritative predictions and the front and swell forecast issued by the Instituto de Meteorología de Cuba.
