About the tides at Georgiana Slough 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 Port Chicago, Suisun Bay. The average range is about 2.4 ft. Spring tides add a little more at both ends. That is smaller than most California stations on this site. The next spring tides peak on October 28, with a range of 4.0 ft. Neap tides follow on Monday, when the range shrinks to 2.4 ft. In the next 12 months the highest predicted tide here is 4.1 ft on July 4, and the lowest is −0.3 ft on December 26.

Georgiana Slough entrance is a subordinate station. NOAA predicts its tides by adjusting Port Chicago, Suisun Bay: highs come about 209 min and lows about 221 min later than there. NOAA measured the tide here from 1977 to 1979 to set up these predictions. The nearest other station is Korths Harbor, 2 mi away, where high tide comes about 21 min earlier. For tidal currents, see Sacramento River Light 14.

Predictions are based on Port Chicago, Suisun Bay.
