About this station
NOAA builds the predictions for Kasnyku Bay from the Juneau station: high tides adjusted -2.4 ft, 10 min earlier; low tides adjusted -0.1 ft, 6 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.
