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/Costa Rica local. Folk tradition, not a scientific forecast.

Next spring tide on Fri 01 May (range 2.3m). Last neap on Wed 29 Apr. Next neap on Mon 04 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Manuel Antonio sits on the central Pacific coast of Costa Rica in Puntarenas province, a few kilometres south of the working sport-fishing harbour at Quepos. The coast here is the south-facing shore of a forested headland that drops in steep ridges to a series of sheltered crescent beaches inside Manuel Antonio National Park — one of the smallest but most-visited national parks in Costa Rica, where the rainforest reaches the high-tide line and white-faced capuchins, three-toed sloths, and squirrel monkeys move through the canopy directly above the sand. The tide here is mixed semidiurnal with a large range typical of the eastern tropical Pacific. Mean astronomical range runs roughly 1.8 to 2.5 metres above chart datum, with spring tides around new and full moons pushing past 2.7 to 3.0 metres and neap tides during the quarter moons compressing toward 1.0. Two highs and two lows of unequal size each day, about twelve and a half hours apart, with the bigger swing typically falling on the lower-low water. Punta Catedral is the rocky headland at the centre of the park — a tombolo-like feature that connects to the mainland by a sand bridge between Playa Espadilla Sur on the north side and Playa Manuel Antonio on the south side. At high water the sand bridge narrows to a strip; at the lowest spring lows it widens dramatically and the rocky tide-pool zone around the base of the headland reveals an exposed shelf with sea urchins, hermit crabs, and the small reef fish that local snorkellers target. The forested top of Punta Catedral carries a network of park trails and viewpoints over both flanking beaches, and the headland is the visual centrepiece of the park from any of the boat approaches running south from Quepos. Playa Espadilla Sur and Playa Manuel Antonio inside the park are the most photographed beaches on the central Pacific coast and run a meaningful tide swing — the wet-sand zone shifts roughly 30 to 50 metres between high and low water on a typical spring tide, and the morning shadow line off the headland walks across that wet sand as the sun climbs. Playa Espadilla outside the park boundary to the north is the working surf beach for the town, and the river-mouth peak at the southern end works the changing tide; the rip current that builds on the dropping tide here is one of the standard caution signals along the central Pacific coast and the local lifeguards monitor it on a daily cycle. Playa Biesanz, the small protected cove tucked into the headland west of the main park entrance, runs a calmer signal and is one of the few beaches in the area where snorkelling is reliable on the slack between flood and ebb. Sport-fishing pangas running out of Quepos harbour just north of Manuel Antonio target sailfish and marlin offshore on the El Niño and La Niña current cycles; estuary anglers in the Río Naranjo and Río Savegre mouths read the incoming tide for snook and corvina, and the river-mouth zones reveal extensive sand-bar exposure on the lowest spring lows. The Marina Pez Vela at Quepos is the operational reference for the local sport-fishing fleet and reads the tide for harbour ingress and egress, particularly for the larger boats that need the higher water in the channel approach. Beach-walking families and wildlife watchers timing the park's main trail circuits read the same predictions to align their loops with low-water beach access. The predictions on this page come from Open-Meteo Marine, a free gridded global ocean model that estimates tidal height across a geographic grid rather than from a measured harmonic record. Accuracy is typically within plus or minus 45 minutes on timing and within roughly 0.3 metres on height — small relative to Manuel Antonio's two-metre-plus mean swing, but worth knowing when planning the lowest-low photography window at Punta Catedral or the snorkelling slack between flood and ebb at Playa Manuel Antonio. The Costa Rican Instituto Geográfico Nacional and Universidad de Costa Rica's CIMAR (Centro de Investigación en Ciencias del Mar y Limnología) are the regional authoritative references; Puerto Caldera at the entrance to the Gulf of Nicoya is the closest reference port for the central Pacific gauge.
