About this station

NOAA builds the predictions for Wachusett Inlet, Glacier Bay from the Elfin Cove, Port Althorp station: high tides about 1.57× the height, 39 min later; low tides about 1.20× the height, 50 min later.

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.
