About the tides at Hog Island

Tides here are mixed. On average the two daily highs differ by 1.0 ft, so check which low is the lower one before you head out. The pattern follows the reference station at San Francisco, San Francisco Bay. The average range is about 4.6 ft. Spring tides add a little more at both ends. In the next 12 months the highest predicted tide here is 7.7 ft on December 24, and the lowest is −1.4 ft on December 24.

Hog Island is a subordinate station. NOAA predicts its tides by adjusting San Francisco, San Francisco Bay: highs come about 107 min and lows about 156 min later than there. NOAA measured the tide here from 1979 to 1980 to set up these predictions. The nearest other station is Petaluma River entrance, 4 mi away, where high tide comes about 24 min earlier. For tidal currents, see Petaluma River entrance.

Predictions are based on San Francisco, San Francisco Bay.
