About this station
Martinez-Amorco Pier is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
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.
