About this station
NOAA builds the predictions for Steamboat Bay, Noyes Island from the Sitka station: high tides about 1.04× the height, 12 min earlier; low tides about 0.93× the height, 13 min earlier.
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.
