About this station

NOAA builds the predictions for Newark Slough from the SAN FRANCISCO (Golden Gate) station: high tides adjusted +2.6 ft, 71 min later; low tides adjusted +0.1 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.
