About this station
NOAA builds the predictions for Copper Harbor from the Sitka station: high tides adjusted +2.8 ft, 10 min earlier; low tides adjusted +0.1 ft, 8 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.
