About this station
NOAA builds the predictions for Tomales Bay entrance from the SAN FRANCISCO (Golden Gate) station: high tides about 0.87× the height, 12 min earlier; low tides about 0.91× the height, 20 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.
