About the tides at Potrero Point
This is a mixed-tide station. Some days bring a deep low and a shallow low, and a few days have only one of each. The pattern follows the reference station at San Francisco, San Francisco Bay. The average range is about 4.4 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 −1.8 ft on December 24.
Potrero Point is a subordinate station. NOAA predicts its tides by adjusting San Francisco, San Francisco Bay: highs come about 33 min and lows about 46 min later than there. The nearest other station is Rincon Point, 2 mi away, where high tide comes about 12 min earlier. For tidal currents, see Mission Rock, 0.6 mile east of.
Predictions are based on San Francisco, San Francisco Bay.
