About this station
NOAA builds the predictions for San Mateo Bridge (east end) from the SAN FRANCISCO (Golden Gate) station: high tides adjusted +1.8 ft, 48 min later; low tides adjusted +0.0 ft, 79 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.
