About this station
NOAA builds the predictions for Cleveland Passage, Whitney Island from the Juneau station: high tides adjusted -1.2 ft, 1 min earlier; low tides adjusted -0.1 ft, 3 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.
