About this station
NOAA builds the predictions for Kupreanof Harbor, Paul Island from the KODIAK, Womens Bay station: high tides about 0.89× the height, 19 min later; low tides about 1.28× the height, 35 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.
