About this station
NOAA builds the predictions for Thorne Island, Whale Passage from the Ketchikan station: high tides about 1.04× the height, 12 min later; low tides about the same height, 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.
