About this station
NOAA builds the predictions for Kell Bay, Affleck Canal, Kuiu Island from the Sitka station: high tides adjusted +1.3 ft, 1 min later; low tides adjusted +0.0 ft, 1 min later.
Inside Passage waters are sheltered, but the ranges are real: 15 to 20 ft swings are routine, and narrow channels run strong tidal currents on the change. Out here, rain and channel weather matter more than ice.
