SPRING AND NEAP CYCLE

Cycle dates near San Diego, CA

Next spring tide on Sun 17 May (range 2.7m / 8.8ft). Last neap on Fri 15 May. Next neap on Sat 23 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.

EDITORIAL

About tides at San Diego, CA

San Diego sits on a long, sheltered bay where the tide arrives quietly compared to the open Pacific outside Point Loma. The mean range is about 1.7 m, and the daily pattern is mixed semidiurnal — two highs and two lows of unequal size. The bigger swing happens around the lower-low water, which is what NOAA measures everything from. That matters if you're walking the Embarcadero, paddling out of Shelter Island, or eyeing the tide pools at Cabrillo. La Jolla's tide pools further north open up reliably in the lowest tides of the month, around the new and full moons. The harbour entrance stays navigable across the cycle, but small-craft sailors heading out of Mission Bay watch the channel on the ebb when current and chop combine. Predictions on this page come from NOAA CO-OPS station 9410170 — harmonic analysis of decades of gauge data, very high accuracy under normal weather. Storm surge from Pacific lows can shift actual water level by 10–20 cm; the predictions assume calm.

COMMON QUESTIONS

Tide questions about San Diego, CA

When is the next high tide at San Diego?

The hero block at the top of this page shows the next high tide at San Diego, with the time in local Pacific time and the height above MLLW (mean lower low water — NOAA's reference). For the full pattern over the next week, scroll to the 7-day table below. NOAA updates its harmonic predictions continuously; this page rebuilds daily.

What's the typical tide range at San Diego?

Mean range at San Diego is about 1.7 metres between mean low water and mean high water. Spring tides — around new and full moons — push the range to roughly 2.1 metres. Neap tides during quarter moons compress it to around 1.2 metres. The biggest swings of the year happen around the perigean spring tides in winter and summer, when the moon is closest to Earth at the same time as new or full phase.

Where do these tide predictions come from?

NOAA CO-OPS station 9410170 in San Diego Bay. NOAA computes predictions through harmonic analysis of decades of measured water levels at this exact gauge. That's the gold-standard method for tide prediction in US waters and produces accuracy you can plan a clamming trip or a kayak crossing around. See /methodology for the full explanation.

When are the lowest tides for tide pooling at San Diego?

The lowest low tides — minus tides below the MLLW reference — cluster around new and full moons, especially in late autumn and winter. Cabrillo National Monument's tide pools and the La Jolla pools open up best when the predicted low is below 0 metres MLLW for an hour or more either side. The 7-day table on this page flags the lowest predicted tide for each day.

Is this safe to use for navigation?

No. TideTurtle is a planning tool, not a nautical almanac. For navigation in or out of San Diego Harbour, use NOAA's authoritative chart products and the latest local notices to mariners. Storm surge, wind setup, and currents can shift actual water levels and times beyond what harmonic prediction captures.
