About this station
NOAA builds the predictions for Gold Street Bridge, Alviso Slough from the SAN FRANCISCO (Golden Gate) station: high tides about 1.67× the height, 63 min later; low tides about 0.96× the height, 141 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.
