About this station

NOAA builds the predictions for Snodgrass Slough from the PORT CHICAGO, SUISUN BAY station: high tides about 0.49× the height, 300 min later; low tides about 0.39× the height, 336 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.
