About the tides at Boston

Expect two roughly equal high tides a day at Boston, each arriving about 50 minutes later than the day before. With a mean range of about 9.5 ft, the shoreline here changes a lot between high and low water. That is larger than most Massachusetts stations on this site. From the average lower low to the average higher high, the difference is 10.3 ft. Over the next two weeks the biggest daily range, 10.9 ft, comes on Sunday, and the smallest, 6.4 ft, on October 18. Looking a year ahead, predictions peak at 11.8 ft on November 26 and bottom out at −1.8 ft on January 23.

A live NOAA gauge measures the water here, and predictions are calculated from this station's own records. It also reports air pressure. It was established in 1921. The nearest other station is Charlestown, 1 mi away. For tidal currents, see South Boston, Pier 4, 0.2 n.mi. Nne of.
