About this station
NOAA builds the predictions for Irish Landing, Sand Mound Slough from the PORT CHICAGO, SUISUN BAY station: high tides about 0.73× the height, 209 min later; low tides about 0.68× the height, 214 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.
