About this station
NOAA builds the predictions for Usof Bay from the Unalaska station: high tides about 1.55× the height, 210 min earlier; low tides about 1.19× the height, 225 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.
