About the tides at Zachary Bay

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 range is large, about 5.4 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is smaller than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 7.4 ft. The next spring tides peak on October 11, with a range of 8.8 ft. Neap tides follow today, when the range shrinks to 5.7 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 1954 to 2017 to set up these predictions. The nearest other station is Sand Point, 4 mi away. For tidal currents, see Popof Strait.
