About the tides at Petaluma River entrance

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 4.5 ft. Spring tides add a little more at both ends. From the average lower low to the average higher high, the difference is 6.0 ft. The next spring tides peak on October 28, with a range of 8.0 ft. Neap tides follow today, when the range shrinks to 2.4 ft. In the next 12 months the highest predicted tide here is 7.7 ft on December 24, and the lowest is −1.6 ft on December 24.

Petaluma River entrance is a subordinate station. NOAA predicts its tides by adjusting San Francisco, San Francisco Bay: highs come about 83 min and lows about 128 min later than there. NOAA measured the tide here from 1977 to 2014 to set up these predictions. The nearest other station is Hog Island, 4 mi away, where high tide comes about 24 min later. For tidal currents, see Petaluma River entrance.

Predictions are based on San Francisco, San Francisco Bay.
