About this station

NOAA builds the predictions for Reynolds, Tomales Bay from the SAN FRANCISCO (Golden Gate) station: high tides about 0.89× the height, 26 min later; low tides about 0.83× the height, 119 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.
