About the tides at Charlestown

Expect two roughly equal high tides a day at Boston Naval Ship., Charlestown, each arriving about 50 minutes later than the day before. The pattern follows the reference station at Boston, Boston Harbor. The range is large, about 9.1 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. In the next 12 months the highest predicted tide here is 11.8 ft on November 26, and the lowest is −1.8 ft on January 23.

Charlestown is a subordinate station. NOAA predicts its tides by adjusting Boston, Boston Harbor: highs come about 0 min and lows about 1 min later than there. The nearest other station is Boston, 1 mi away. For tidal currents, see Charles River Entrance.

Predictions are based on Boston, Boston Harbor.
