About this station

NOAA builds the predictions for Prisoners Harbor, Santa Cruz Island from the LOS ANGELES (Outer Harbor) station: high tides about 0.94× the height, 19 min later; low tides about the same height, 18 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.
