About this station
NOAA builds the predictions for Ukolnoi Island from the SAND POINT, POPOF ISLAND station: high tides about 0.97× the height, 7 min later; low tides about the same height, at the same time.
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.
