About this station
NOAA builds the predictions for Tamgas Harbor, Annette Island from the Ketchikan station: high tides about the same height, 9 min earlier; low tides about 0.89× the height, 8 min earlier.
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.
