About this station
NOAA builds the predictions for Rasp Ledge, Seymour Canal from the Juneau station: high tides adjusted -0.7 ft, 6 min later; low tides adjusted +0.1 ft, 5 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.
