About this station
NOAA builds the predictions for Udagak Strait from the Unalaska station: high tides about 1.37× the height, 212 min earlier; low tides about the same height, 239 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.
