NOAA builds the predictions for Finch Cove, Seguam Island from the Sweeper Cove, Kuluk Bay, Adak Island station: high tides about 0.87× the height, 60 min earlier; low tides about 0.87× the height, 7 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.
