About the tides at Chowiet Island

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. With a mean range of about 6.7 ft, the shoreline here changes a lot between high and low water. From the average lower low to the average higher high, the difference is 9.0 ft. Over the next two weeks the biggest daily range, 11.1 ft, comes today, and the smallest, 6.5 ft, tomorrow.

Predictions for Chowiet Island come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here from 1925 to 2001 to set up these predictions. The nearest other station is Chirikof Island, 41 mi away, where high tide comes about 26 min earlier.
