About this station
NOAA builds the predictions for Santa Ana River entrance (inside) from the LOS ANGELES (Outer Harbor) station: high tides about 0.54× the height, 23 min later; low tides about 0.20× the height, 107 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.
