About this station
NOAA builds the predictions for Port Chatham from the SELDOVIA, Kachemak Bay station: high tides about 0.78× the height, 28 min earlier; low tides about 0.92× the height, 34 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.
