About this station
NOAA builds the predictions for St. Matthew Island from the Village Cove, St. Paul Island station: high tides about 0.61× the height, 6 min later; low tides about 0.61× the height, 29 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.
