About this station
NOAA builds the predictions for Eshamy Bay, Knight Island Passage from the CORDOVA station: high tides adjusted -0.4 ft, 1 min later; low tides adjusted +0.0 ft, 4 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.
