About this station
NOAA builds the predictions for Tanaga Bay from the Sweeper Cove, Kuluk Bay, Adak Island station: high tides about 1.08× the height, 6 min earlier; low tides about 1.08× the height, 32 min earlier.
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.
