About this station
NOAA builds the predictions for Elbow Passage, Klag Bay from the Elfin Cove, Port Althorp station: high tides about the same height, 8 min later; low tides about 1.03× the height, 13 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.
