About this station
NOAA builds the predictions for Swanson Harbor from the Elfin Cove, Port Althorp station: high tides about 1.41× the height, 14 min later; low tides about 1.08× the height, 11 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.
