About the tides at Duwamish Waterway

Duwamish Waterway has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The pattern follows the reference station at SEATTLE (Madison St.), Elliott Bay. With a mean range of about 7.3 ft, the shoreline here changes a lot between high and low water. Over the next two weeks the biggest daily range, 12.1 ft, comes today, and the smallest, 6.5 ft, on October 11.

Tides here are worked out from the reference station at SEATTLE (Madison St.), Elliott Bay, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Lockheed Shipyard, 4 mi away, where high tide comes about 11 min earlier. For tidal currents, see Harbor Island West.

Predictions are based on SEATTLE (Madison St.), Elliott Bay.
