About this station
NOAA builds the predictions for Peterson Bay from the SAND POINT, POPOF ISLAND station: high tides about 0.83× the height, 5 min earlier; low tides about 1.05× the height, 8 min earlier.
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.
