Quick answers

When is the next good low tide at Pillar Point Harbor (Half Moon Bay)?

Jul 14, 2026 (Tue): a -1.8 ft low at 5:33 AM, walkable from 2:45 AM to 8:45 AM — score 82/100. Computed from NOAA station 9414131 predictions.

How low does the tide need to be at Pillar Point Harbor (Half Moon Bay)?

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 Pillar Point Reef is at its best.

How many daylight minus tides does Pillar Point Harbor (Half Moon Bay) get in the next 30 days?

13 of the next 30 days' 16 minus tides overlap daylight by at least 30 minutes, as of 2026-07-04. 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.
