About this station

Kalgin Island (north end), Cook Inlet is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.

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.
