About this station
NOAA builds the predictions for Unavikshak Island from the KODIAK, Womens Bay station: high tides about 1.05× the height, 31 min later; low tides about 1.24× the height, 44 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.
