About this station
NOAA builds the predictions for Blashke Island from the Ketchikan station: high tides about 1.03× the height, 13 min later; low tides about 0.93× the height, 24 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.
