About the tides at Chelsea St. Bridge

Chelsea St. Bridge has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. With a mean range of about 9.6 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 10.4 ft. Over the next two weeks the biggest daily range, 11.8 ft, comes today, and the smallest, 9.1 ft, on Sunday.

Predictions for Chelsea St. Bridge come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here in 2002 to set up these predictions. The nearest other station is Charlestown, 2 mi away, where high tide comes about 7 min earlier. For tidal currents, see Chelsea River, below bascule bridge.
