About this station
NOAA builds the predictions for Smith Slough from the SAN FRANCISCO (Golden Gate) station: high tides adjusted +2.1 ft, 75 min later; low tides adjusted +0.0 ft, 118 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.
