About this station
NOAA builds the predictions for Ratz Harbor, Prince of Wales Island from the Ketchikan station: high tides about 1.03× the height, 9 min later; low tides about the same height, at the same time.
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.
