About the tides at Harper

This is a mixed-tide station. Some days bring a deep low and a shallow low, and a few days have only one of each. With a mean range of about 7.7 ft, the shoreline here changes a lot between high and low water. Over the next two weeks the biggest daily range, 12.7 ft, comes today, and the smallest, 6.9 ft, on October 11.

Harper is a subordinate station, so NOAA publishes only its high and low times and heights. The nearest other station is Point Vashon, 3 mi away, where high tide comes about 8 min later. For tidal currents, see Blake Island, S of.
