Santa Monica, CA tide times

Predictions: NOAA CO-OPS station 9410840 — heights relative to MLLW.

Harmonic prediction from the official tide authority. Very high accuracy under normal conditions; storm surge may shift actual water level. Not for navigation.

Marine-conditions data not available for this station. Wind, swell and water temperature ride along with Open-Meteo Marine; gauge-only stations (e.g. UK EA Flood) publish water level only.

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/Los Angeles local. Folk tradition, not a scientific forecast.

Next spring tide on Sun 17 May (range 2.6m / 8.6ft). Last neap on Fri 15 May. Next neap on Sun 24 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.

Santa Monica's tide gauge sits at the end of the pier, the same pier that anchors the boardwalk between the bluffs and the sand. The pattern is mixed semidiurnal — two highs and two lows of unequal size each day — with the bigger swing falling on the lower-low water. Mean range is about 1.1 metres at the pier, climbing toward 1.5 on spring tides. Santa Monica Bay opens straight out to the Pacific between Point Dume and Palos Verdes, so the swing here reads close to the open-coast Southern California signal: gentle compared to the Pacific Northwest, but enough to reshape the beach over a single cycle. The wide sand of Santa Monica and Venice loses 10–20 metres of width on the high and gets it back on the low, and the dawn beach-walk crowd reads the table to time their out-and-back along the firmer wet sand. Surfers between First Point Malibu and Sunset read the same table for the way low water reshapes the inside section. Predictions on this page come from NOAA CO-OPS station 9410840. Pacific storm setup in winter can lift water levels 10–20 cm above predicted; the harmonic forecast assumes calm.
