About the tides at Port William

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. The tide range here is very large, about 11.4 ft on average. Water can come in faster than you can walk across flats. Check the time before you go out. That is larger than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 13.9 ft. The next spring tides peak on October 11, with a range of 17.6 ft. Neap tides follow on Sunday, when the range shrinks to 10.0 ft.

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 from 1971 to 2024 to set up these predictions. The nearest other station is Redfox Bay, 3 mi away, where high tide comes about 16 min earlier. For tidal currents, see Lighthouse Point, Shuyak Island.
