About this station

NOAA builds the predictions for Alameda Naval Air Station from the SAN FRANCISCO (Golden Gate) station: high tides about 1.11× the height, 24 min later; low tides about the same height, 33 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.
