Loreto 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.

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

Next spring tide on Sun 17 May (range 1.5m). Next neap on Wed 20 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.

Loreto is on the Sea of Cortez coast of Baja California Sur, backed by the Sierra de la Giganta and facing the Loreto Bay National Marine Park — an archipelago of five islands (Carmen, Danzante, Monserrat, Santa Catalina, and Coronados) that protect a section of the 'world's aquarium' as Jacques Cousteau named it. Tidal pattern is mixed semidiurnal with a mean spring range of about 0.6 to 1.0 metres in the central Sea of Cortez. The tidal range increases dramatically toward the northern end of the Cortez (reaching 6+ metres at the Colorado River mouth), but at Loreto's latitude it remains moderate. The Loreto Bay National Marine Park covers 2065 km² and prohibits commercial fishing within its boundaries. The results are visible in the fish density — the reefs and kelp zones around the five islands hold some of the highest concentrations of large grouper, snapper, and roosterfish in Mexican waters. Sport fishing from Loreto targets dorado (mahi-mahi) in summer, yellowtail in winter, and roosterfish from shore and panga year-round. The daily panga (small motorboat) fishing trips departing from the Loreto waterfront are a direct-access route to productive fishing within 20 minutes of the dock. Kayaking in the Loreto Bay archipelago is one of the premier multi-day paddling trips in North America. The standard route launches from the beach at Loreto, paddles to Coronados Island (5 km), then proceeds south through the passage between Carmen and Danzante islands, camping on beaches accessible only by sea. The Sea of Cortez is calm in the morning; afternoon winds (cohuanas from the south or winds from the north) build 15 to 20 knots by 2 p.m. — plan morning crossings, camp by noon. Whale watching near Loreto focuses on blue whales in winter (December through March), when the largest animals on earth feed in the deep-water zones south of the archipelago. Blue whale sightings near Loreto are reliable from December through March; the animals are visible from panga tours from the waterfront. Finback whales are also common in winter; dolphins (bottlenose, common) are year-round residents. Snorkelling on the reefs around Coronados and Carmen islands produces encounters with leopard grouper, Moorish idols, sergeant major damselfish, and sea lions (California sea lion colonies on several islands). Water temperature ranges from 18°C in winter to 29°C in August. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
