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/Bogota local. Folk tradition, not a scientific forecast.

Last spring tide on Wed 06 May (range 2.2m). Next spring tide on Tue 12 May (range 2.4m). 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.

Juanchaco is a small beach village on the open Pacific coast of the Colombian department of Valle del Cauca, accessible only by boat from Buenaventura — a 2–2.5 hour lancha (motorised boat) crossing across Buenaventura Bay and through the outer channels to the open coast. The village sits on a narrow strip of sand backed by Chocó rainforest, facing west-southwest into the full Pacific. There are no roads to Juanchaco; electricity is generator-based; accommodation is simple. This inaccessibility is the defining characteristic: it preserves a raw, genuinely coastal settlement that has not been smoothed by resort infrastructure. The tidal regime at Juanchaco is macrotidal mixed semidiurnal. Spring range at nearby Buenaventura reaches 4.0–5.0 m above Chart Datum — among the largest tidal ranges on the Pacific coast of South America north of Chile. The Colombian Pacific coast has a pronounced macrotidal character, and the Juanchaco open coast sits within this same high-range regime. Two highs and two lows occur per day with significant diurnal inequality; on some lunar phases one high is 1.0–1.5 m above the other. At spring low water the beach extends substantially seaward of the high-water mark — the full 4.0–5.0 m range translates to 200–300 m of additional beach on the gently sloping sand profile. At spring high water the same beach is narrow, with wave action reaching the vegetation line in some sections. Juanchaco's primary draw from July through November is humpback whale watching. The warm, shallow waters immediately offshore — held warm by the absence of the cold Humboldt upwelling that dominates the Ecuador and Peru coast to the south — attract humpback whales (Megaptera novaeangliae) from their Antarctic feeding grounds to calve and breed. The concentration of whales in this relatively compact area, combined with the high productivity of the Chocó-Pacific ecological corridor, makes the whale-watching here among the most reliable in the world. Boats depart Juanchaco in the early morning; sightings are independent of tide state but calmer morning sea conditions improve the experience. The village beach at Juanchaco on the north side is more sheltered than the exposed beach at Ladrilleros, 2 km south; Juanchaco's beach is calmer in the afternoon when the SW sea breeze is less direct. Shore fishing from the beach targets corvina and trevally on the incoming tide. The rocks at the northern end of the Juanchaco beach, exposed at low water, are an accessible intertidal zone for observation. DIMAR (Dirección General Marítima) publishes Colombian Pacific tide tables. Predictions here: Open-Meteo Marine, ±45 min / ±0.2–0.3 m. The village accommodates visitors in basic family-run hospedajes (guesthouses) and a small number of cabins; there are no hotels in the resort sense. Electricity comes from a communal generator that operates set hours; mobile phone reception is limited. The village economy is split between fishing and whale-watching tourism; the two months of peak whale season (August–September) generate income that supports the rest of the year. Local families have become expert whale-watching guides over two generations of the industry's growth, and the encounters they facilitate from small open boats are characterised by patience and local knowledge that larger operations from Buenaventura cannot replicate. The Colombia Pacific coast between Buenaventura and the border with Ecuador is one of the least-developed stretches of Pacific coast in South America; the combination of Chocó rainforest, high rainfall (3,000–8,000 mm/year), and limited road access has preserved the natural character. Juanchaco and Ladrilleros represent the most accessible point of this coast from a major Colombian city; the two villages function as the entry points for nature tourism (whale watching, humpback migration, coastal ecology) on a coast that has very few such entry points.
