About this station
NOAA builds the predictions for Marshall, Tomales Bay from the SAN FRANCISCO (Golden Gate) station: high tides adjusted -0.6 ft, 38 min later; low tides adjusted -0.1 ft, 76 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.
