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 Tue 05 May (range 2.0m). Next neap on Sat 09 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.

Quepos is a working port town on Costa Rica's central Pacific coast, in Puntarenas province, situated at the intersection of sportfishing infrastructure and one of the country's most-visited national parks. The marina is a serious facility; the park, 7 km south, draws hundreds of thousands of visitors per year. The tide is the thread connecting both. The Pacific at Quepos runs semidiurnal with diurnal inequality — two highs and two lows per day, with one daily high consistently larger than the other. Mean spring range is 2.5–3.5 m, the same tidal regime that governs the entire Costa Rican Pacific coast south of the Nicoya Peninsula. Neap tides bring that range down to 1.0–1.5 m. Datum is mean lower low water (MLLW). The largest tides of the year occur during the December and June new and full moons, when ranges can push toward 3.5 m. Marina Pez Vela, Quepos's full-service marina, is the primary infrastructure reference point for anyone bringing a vessel here. The approach channel carries 3.5–4.0 m at low spring tide — enough for most keelboats and the large charter sportfishing vessels (typically 30–43 feet with 1.2–1.5 m draft) that make up the bulk of the marina traffic. Channel clearance at high tide adds the tidal range: on a spring high of 3.0 m, the approach carries 6.5–7.0 m, which is sufficient for the occasional larger yacht transiting the Central American Pacific. The channel entrance is protected by a concrete breakwater. Current at the entrance runs 1–2 knots on spring tidal exchanges — nothing demanding for a crewed vessel, but worth timing if you are single-handing something with limited auxiliary power. Enter and exit Quepos Marina within one hour of slack water for the most comfortable approach. The Boca Vieja estuary sits immediately north of the marina. This is a tidal mangrove system — channels cutting through mangrove forest that floods and drains with each tidal cycle. The flood tide is the productive window for fishing here: as water rises, snook (Centropomus undecimalis) and cubera snapper (Lutjanus cyanopterus) push out of the deeper channel into the mangrove fringe to feed on the baitfish and crustaceans flushed from the roots. Most local guides target the first two hours of the flood, beginning approximately 90 minutes before the predicted high. The ebb reverses the opportunity — fish drop back into the main channel as the mangrove drains. Fly fishing and light spin tackle are both productive here; the fish are not large by offshore standards but the mangrove setting makes for tight, technical work. Seven kilometres south, Manuel Antonio National Park holds three beaches that are directly tide-controlled in their character and accessibility. Playa Espadilla Norte is outside the park boundary and connects at low water to the park entrance beach. Playa Manuel Antonio, inside the park, is sheltered and calm — a half-moon bay with gentle swimming suitable for families at any tidal stage. Playa Biesanz is a smaller cove further inside the park, accessible only on foot, with good snorkelling on its rock outcrops at low to mid tide when visibility improves. The most photographed tidal feature in Manuel Antonio is the tombolo connecting the main beach to El Perezoso, a forested island just offshore from Playa Espadilla Norte. A tombolo is a sand bar linking an island to the mainland — at low tide, typically 0.5 m or below MLLW, the sand connection becomes walkable and the island is accessible on foot. At high spring water, the tombolo is submerged by 0.5–0.8 m and the island is entirely cut off. The transition happens fast: from a 3.0 m spring high, the water drops 1.5 m in roughly three hours, so the tombolo can go from knee-deep to ankle-deep to dry sand in under two hours. Check the tide table before crossing — the return window can close faster than expected if you linger on the island. Quepos's offshore sportfishing targets are among the best on the Pacific coast. Pacific sailfish (Istiophorus platypterus) are present year-round, with peak months November through April. The boats leave Marina Pez Vela before 06:00 on most fishing days, timing the offshore run to reach productive water around first light. Tidal state matters less offshore than inshore — sailfish follow current breaks and temperature gradients — but inshore structure fishing around the headlands south of the marina is tide-sensitive, with the ebb exposing rocky structure that holds roosterfish and jack crevalle.
