About this station
NOAA builds the predictions for Mystery Bay, Marrowstone Island from the PORT TOWNSEND station: high tides about 0.95× the height, 15 min later; low tides about the same height, 52 min later.
Puget Sound and the Columbia estuary amplify mixed tides far inland — ranges past 10 ft in the South Sound — with river flow stacked on top.
