About the tides at Sumner Island

Sumner Island 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 Sitka. Sumner Island sees a mean range of about 10.1 ft. Low tide can expose a wide area, and the return is fast. Over the next two weeks the biggest daily range, 14.5 ft, comes on October 11, and the smallest, 8.2 ft, on Friday.

Tides here are worked out from the reference station at Sitka, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Reid Bay, 4 mi away, where high tide comes about 8 min later. For tidal currents, see Sumner Island, east of.

Predictions are based on Sitka.
