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 average range is about 4.5 ft. Spring tides add a little more at both ends. The next spring tides peak today, with a range of 6.9 ft. Neap tides follow tomorrow, when the range shrinks to 3.9 ft.
Petaluma River entrance is a subordinate station, so NOAA publishes only its high and low times and heights. 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.
