The pattern

Two unequal highs and two unequal lows daily with around five feet of range at Pillar Point. The harbor’s breakwater tames the ocean side; the minus tides expose the reef’s intertidal life.

Mavericks and crab

Mavericks breaks biggest on the winter swells — tide is secondary to swell, but the paddle-out reads the water. The commercial fleet works salmon and Dungeness crab in season; the jetties give up perch and rockfish.

Boating

Pillar Point is the coast’s refuge harbor — mind the entrance in big surf. Outside is open ocean: check swell with the tide. For the region, see our Central & Northern California tide guide.
