Quick answers

When is the next good low tide at San Diego (Cabrillo)?

Oct 25, 2026 (Sun): a -0.3 ft low at 3:31 PM, walkable from 1:35 PM to 5:30 PM — score 65/100. Computed from NOAA station 9410170 predictions.

How low does the tide need to be at San Diego (Cabrillo)?

Tidewindow counts a window whenever the predicted height falls below +1.0 ft MLLW, and scores depth from +0.5 ft (0 points) to −2.0 ft (50 points). The lower the tide, the more of the intertidal zone is exposed — minus tides (below 0 ft) are when Cabrillo National Monument tidepools is at its best.

How many daylight minus tides does San Diego (Cabrillo) get in the next 30 days?

6 of the next 30 days' 9 minus tides overlap daylight by at least 30 minutes, as of 2026-10-04. The full list is in the table above.

Safety: tide predictions are astronomical forecasts, not observations — wind and swell change actual water levels. Follow posted rules at protected areas, and never turn your back on the ocean. See our methodology for exactly how windows and scores are computed.
