About the tides at Seavey Island

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.8 ft. With a mean range of about 8.2 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 8.9 ft. Looking a year ahead, predictions peak at 10.3 ft on December 25 and bottom out at −1.5 ft on January 23.

A live NOAA gauge measures the water here, and predictions are calculated from this station's own records. It also reports water temperature and air pressure. It was established in 1926. The nearest other station is Portsmouth, 0.5 mi away. For tidal currents, see Pierces Island, northeast of.
