About this station
NOAA builds the predictions for Brazos Drawbridge, Napa River from the SAN FRANCISCO (Golden Gate) station: high tides about 1.14× the height, 122 min later; low tides about 0.86× the height, 149 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.
