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. 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, 11.6 ft, comes today, and the smallest, 8.7 ft, on Sunday.
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.
