About this station
NOAA builds the predictions for San Diego, Quarantine Station from the SAN DIEGO (Broadway) station: high tides about 0.96× the height, 4 min earlier; low tides about 0.96× the height, 2 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.
