About this station

NOAA builds the predictions for Sanak Harbor from the SAND POINT, POPOF ISLAND station: high tides about 0.89× the height, 14 min later; low tides about 1.05× the height, 3 min later.

Alaska holds the country's most extreme tides: Inside Passage channels, Cook Inlet swings past 30 ft, and Arctic stations where the tide is measured in inches and wind setup runs the show.
