About this station

NOAA builds the predictions for Reid Bay from the Sitka station: high tides adjusted +2.5 ft, 11 min earlier; low tides adjusted +0.0 ft, 19 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.
