About Alaska tides

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.

Alaska has 524 NOAA tide stations — 261 reference stations whose predictions come from harmonic analysis of observations there, and 263 subordinate stations calculated from them. The biggest tidal range in the state is at Goose Creek, Knik Arm, Cook Inlet — 31.0 ft between mean higher high water and mean lower low water.
