About the tides at Poponesset Island

Expect two roughly equal high tides a day at Poponesset Is., Bay, each arriving about 50 minutes later than the day before. The pattern follows the reference station at Boston, Boston Harbor. The average range is about 2.1 ft. Spring tides add a little more at both ends. That is smaller than most Massachusetts stations on this site. In the next 12 months the highest predicted tide here is 2.8 ft on November 26, and the lowest is −0.4 ft on January 23.

Poponesset Island is a subordinate station. NOAA predicts its tides by adjusting Boston, Boston Harbor: highs come about 123 min and lows about 112 min later than there. The nearest other station is Cotuit Highlands, 2 mi away, where high tide comes about 46 min earlier. For tidal currents, see Cotuit Bay entrance (Bluff Point).

Predictions are based on Boston, Boston Harbor.
