About the tides at Threemile Slough

Threemile Slough has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The pattern follows the reference station at Port Chicago, Suisun Bay. The average range is about 2.9 ft. Spring tides add a little more at both ends. That is smaller than most California stations on this site. In the next 12 months the highest predicted tide here is 5.0 ft on July 4, and the lowest is −0.5 ft on December 25.

Threemile Slough is a subordinate station. NOAA predicts its tides by adjusting Port Chicago, Suisun Bay: highs come about 109 min and lows about 118 min later than there. NOAA measured the tide here from 1977 to 1992 to set up these predictions. The nearest other station is Threemile Slough entrance, 2 mi away, where high tide comes about 49 min later. For tidal currents, see Sacramento River Light 14.

Predictions are based on Port Chicago, Suisun Bay.
