About the tides at Oceanographic Institution

Oceanographic Institution has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. Water here rises and falls only about 1.8 ft on an average day. A strong onshore wind can push levels above the prediction. That is smaller than most Massachusetts stations on this site. From the average lower low to the average higher high, the difference is 2.2 ft. Over the next two weeks the biggest daily range, 2.5 ft, comes on October 10, and the smallest, 1.9 ft, on Monday.

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 1932. The nearest other station is Little Harbor, 0.4 mi away, where high tide comes about 8 min later. For tidal currents, see Juniper Point.
