About this station

NOAA builds the predictions for Klokachef Island from the Sitka station: high tides adjusted -0.1 ft, 10 min earlier; low tides adjusted +0.1 ft, 6 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.
