About this station
NOAA builds the predictions for St. Catherine Cove from the Unalaska station: high tides about 1.23× the height, 4 min later; low tides about 1.36× the height, 18 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.
