About this station
NOAA builds the predictions for Johnstone Point from the CORDOVA station: high tides adjusted -0.8 ft, 7 min earlier; low tides adjusted -0.1 ft, 2 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.
