About this station
NOAA builds the predictions for Security Cove from the Sitka station: high tides adjusted +1.0 ft, 20 min earlier; low tides adjusted +0.0 ft, 24 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.
