About the tides at South Yarmouth

South Yarmouth has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The pattern follows the reference station at Boston, Boston Harbor. The average range is about 2.6 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 3.4 ft on November 26, and the lowest is −0.5 ft on January 23.

South Yarmouth is a subordinate station. NOAA predicts its tides by adjusting Boston, Boston Harbor: highs come about 108 min and lows about 106 min later than there. NOAA measured the tide here in 1983 to set up these predictions. The nearest other station is Dennisport, 4 mi away, where high tide comes about 45 min earlier. For tidal currents, see Dennis Port, 2.2 miles south of.

Predictions are based on Boston, Boston Harbor.
