About this station
Tanapag Harbor, Saipan 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.
Trade-wind shores with small mixed tides — a foot or two in Hawaii, a few feet in the Caribbean — where swell and season matter more than range.
