About the tides at Joice Island
Joice Island 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 4.0 ft. Spring tides add a little more at both ends. From the average lower low to the average higher high, the difference is 5.2 ft. In the next 12 months the highest predicted tide here is 6.6 ft on July 4, and the lowest is −0.6 ft on December 25.
Joice Island is a subordinate station. NOAA predicts its tides by adjusting Port Chicago, Suisun Bay: highs come about 21 min and lows about 41 min later than there. NOAA measured the tide here from 1977 to 1989 to set up these predictions. The nearest other station is Montezuma Slough Bridge, 4 mi away, where high tide comes about 16 min later. For tidal currents, see 1 mile inside west entrance.
Predictions are based on Port Chicago, Suisun Bay.
