About this station
Port William, Shuyak Island 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.
Kodiak ranges run moderate, and the island's bays and passes see strong local currents on big exchanges. Minus tides expose wide reefs and tidepools along the road system.
