About this station
NOAA builds the predictions for Port Graham from the SELDOVIA, Kachemak Bay station: high tides adjusted -1.0 ft, 8 min earlier; low tides adjusted +0.0 ft, 14 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.
