About this station
NOAA builds the predictions for Joice Island, Suisun Slough from the PORT CHICAGO, SUISUN BAY station: high tides about 1.07× the height, 21 min later; low tides about the same height, 41 min later.
Mixed semidiurnal tides — two unequal highs and two unequal lows a day — with ranges growing as you head north. Harbor entrances feel the swell as much as the tide.
