About this station
Holkham Bay, Tracy Arm Entrance is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
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.
