About this station
NOAA builds the predictions for Big Bay, Shuyak Island from the SELDOVIA, Kachemak Bay station: high tides about 0.77× the height, 10 min later; low tides about 0.77× the height, 15 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.
