About the tides at Castle Bay

Tides here are mixed. On average the two daily highs differ by 1.6 ft, so check which low is the lower one before you head out. The range is large, about 6.6 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 8.8 ft. The next spring tides peak on October 11, with a range of 10.5 ft. Neap tides follow on Tuesday, when the range shrinks to 7.0 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 2001 to 2003 to set up these predictions. The nearest other station is Chignik, 5 mi away.
