About this station
NOAA builds the predictions for Raven Bay from the Unalaska station: high tides about 1.49× the height, 196 min earlier; low tides about 1.27× the height, 228 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.
