About the tides at Sandwich Marina
Sandwich Marina has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The range is large, about 8.7 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is larger than most Massachusetts stations on this site. From the average lower low to the average higher high, the difference is 9.5 ft. In the next 12 months the highest predicted tide here is 11.2 ft on December 25, and the lowest is −1.7 ft on January 23.
This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here from 1955 to 2001 to set up these predictions. The nearest other station is Cape Cod Canal, 1 mi away, where high tide comes about 6 min earlier. For tidal currents, see Cape Cod Canal, east end.
