About this station

NOAA builds the predictions for Greys Island from the Ketchikan station: high tides about the same height, 11 min later; low tides about 0.94× the height, 5 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.
