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.

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

Last spring tide on Wed 06 May (range 1.1m). Next spring tide on Tue 12 May (range 1.3m). 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.

Puerto Ayora is the largest town in the Galápagos Islands, located on the southern coast of Santa Cruz Island at the inner edge of Academy Bay (Bahía Academia). The town is the practical hub of the archipelago — tour boats, dive operators, the Charles Darwin Research Station, and the Galápagos National Park Directorate are all here — and Academy Bay is the reference anchorage for the island group. The tidal regime at Puerto Ayora is semidiurnal with moderate diurnal inequality. Spring range runs approximately 1.8–2.2 m above Chart Datum; neap range 0.9–1.2 m. INOCAR operates the Galápagos tide gauge network, and Puerto Ayora is the primary reference station for the central islands. The Charles Darwin Research Station also monitors sea level at Academy Bay as part of the global sea-level monitoring programme. The most immediate tidal geography at Puerto Ayora is the tidal flat immediately west of the main dock area. This flat — a mix of bare rock platform, sand, and algae-coated basalt — hosts one of the most accessible marine iguana colonies in the Galápagos. Marine iguanas (Amblyrhynchus cristatus) are the only sea-going lizards in the world; they feed exclusively on marine algae, diving to depths of 1–5 m and grazing the reef surface. The colony feeds most actively during the low-tide windows when the algae-covered rock is submerged at a depth accessible by short dives — typically from 0.2–0.5 m above Chart Datum, which means the productive feeding window is when the flat is just beginning to flood or is holding at low slack. At high water the iguanas haul out to bask on the warm rocks above the high-tide line, raising their body temperature after the cold-water dives. For visiting naturalists, the best photography of the iguanas feeding occurs in the two-to-three hour window around the predicted low, when the flat is at or near its lowest and the iguanas are concentrated on the exposed rock. In the early morning (06:00–08:00), the flat is also relatively uncrowded and the light is suitable for photography. The anchorage at Academy Bay is well-sheltered; the bay opens to the south but is flanked by the Puerto Ayora headland to the west and Punta Núñez to the east. Tidal current in the bay runs 0.5–1.0 knot at springs, generally NE-SW along the bay axis. Dinghy landings at the main dock are straightforward at all tide states; the public dock steps are calibrated to the tidal range. Tortuga Bay, a pristine white-sand beach accessible by a 2.5 km paved path from town, is reached on foot from the park entrance gate. The bay faces SW and receives a low, consistent swell. At high water the beach is narrower but swimmable at the protected inner cove (Playa Brava is exposed and not recommended for swimming due to current; Playa Mansa at the inner cove is calmer). At low water the beach widens significantly and the shallow cove at Playa Mansa is excellent for snorkelling over the seagrass and sandy bottom where white-tipped reef sharks and sea turtles rest. Snorkelling at the Darwin Research Station pier is possible at high water when the water depth over the reef shelf is sufficient. The sea lion colony on the concrete dock structures of the main pier is present year-round. Tide predictions here come from Open-Meteo Marine: accuracy ±45 min / ±0.2–0.3 m. Official Galápagos tide tables are published by INOCAR. The Charles Darwin Research Station, accessible on foot from the main dock in 15 minutes, runs a Galápagos giant tortoise breeding programme; the juvenile tortoise enclosures are open to visitors. The station's own pier, on the eastern edge of Academy Bay, gives a secondary view of the bay tidal flat and a different angle on the iguana colony at the adjacent rocky foreshore. The road that runs from the Research Station west toward Bahía Academia and the CDRS to the east provides the main walking corridor through the town at low tide, when the waterfront flat is exposed and accessible.
