About the tides at Koyuk

Tides at Koyuk Inlet are mostly diurnal: one rise and one fall a day, with a slow change between them. The average range is about 2.5 ft. Spring tides add a little more at both ends. That is smaller than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 3.0 ft. The next spring tides peak on October 31, with a range of 7.0 ft. Neap tides follow on Sunday, when the range shrinks to 1.2 ft. In the next 12 months the highest predicted tide here is 5.5 ft on July 5, and the lowest is −2.5 ft on December 27.

This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here in 2020 to set up these predictions. The nearest other station is Shaktoolik, 38 mi away, where high tide comes about 2 h 41 m earlier.
