About the tides at Offshore St Matthew Island (Gnss Buoy)

Tides here are mixed. On average the two daily highs differ by 1.0 ft, so check which low is the lower one before you head out. The average range is about 2.2 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 3.2 ft. In the next 12 months the highest predicted tide here is 3.9 ft on November 26, and the lowest is −1.1 ft on December 24.

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 2025 to set up these predictions. The nearest other station is St. Matthew Island, 8 mi away, where high tide comes about 2 h 46 m earlier. For tidal currents, see St. Mathew I., southwest coast.
