About this station
NOAA builds the predictions for Good Island, Gambier Bay from the Juneau station: high tides about 0.93× the height, 5 min earlier; low tides about 0.96× the height, 4 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.
