About the tides at Custom House Cove

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 1.6 ft. Custom House Cove sees a mean range of about 12.8 ft. Low tide can expose a wide area, and the return is fast. That is larger than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 15.2 ft. Over the next two weeks the biggest daily range, 18.5 ft, comes on Sunday, and the smallest, 6.0 ft, on October 17. Looking a year ahead, predictions peak at 18.8 ft on December 24 and bottom out at −3.8 ft on July 5.

Predictions for Custom House Cove come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here in 2010 to set up these predictions. The nearest other station is Alva Bay, 9 mi away. For tidal currents, see Beaver Creek, Mary Island, 0.6 mile W of.
