About this station
Beacon Rock State Park 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.
Puget Sound and the Columbia estuary amplify mixed tides far inland — ranges past 10 ft in the South Sound — with river flow stacked on top.
