About this station
Louis Bay 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.
Prince William Sound ranges run moderate, roughly 10 to 18 ft, but the fjords funnel wind and weather. In the Sound, the storm usually matters more than the tide table.
