About the tides at Portland

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 9.1 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 9.9 ft. Over the next two weeks the biggest daily range, 11.3 ft, comes today, and the smallest, 8.5 ft, on Sunday.

A live NOAA gauge measures the water here, and predictions are calculated from this station's own records. It also reports water temperature, wind and air pressure. It was established in 1910. The nearest other station is Back Cove, 1 mi away. For tidal currents, see State Pier, Portland Harbor.
