About the tides at Poponesset Island

Expect two roughly equal high tides a day at Poponesset Bay, each arriving about 50 minutes later than the day before. The pattern follows the reference station at Boston. The average range is about 2.2 ft. Spring tides add a little more at both ends. That is smaller than most Massachusetts stations on this site. The next spring tides peak today, with a range of 2.8 ft. Neap tides follow on Monday, when the range shrinks to 2.3 ft.

Poponesset Island is a subordinate station. NOAA predicts its tides by adjusting Boston: 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.
