About this station
NOAA builds the predictions for Borden Highway Bridge, Middle River from the PORT CHICAGO, SUISUN BAY station: high tides about 0.67× the height, 290 min later; low tides about 0.62× the height, 294 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.
