About this station
NOAA builds the predictions for Tonki Bay from the KODIAK, Womens Bay station: high tides adjusted +2.3 ft, 12 min later; low tides adjusted +0.2 ft, 21 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.
