About the tides at Great Point

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.3 ft. The pattern follows the reference station at Boston, Boston Harbor. On a typical day the water moves about 2.9 ft between high and low. That is smaller than most Massachusetts stations on this site. Looking a year ahead, predictions peak at 3.8 ft on November 26 and bottom out at −0.6 ft on January 23.

Tides here are worked out from the reference station at Boston, Boston Harbor, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Nantucket, 7 mi away, where high tide comes about 17 min later. For tidal currents, see Great Point, 0.5 mile west of.

Predictions are based on Boston, Boston Harbor.
