About the tides at Chatham Harbor

This is a mixed-tide station. Some days bring a deep low and a shallow low, and a few days have only one of each. On a typical day the water moves about 4.6 ft between high and low. That is smaller than most Massachusetts stations on this site. From the average lower low to the average higher high, the difference is 5.2 ft. Over the next two weeks the biggest daily range, 6.3 ft, comes today, and the smallest, 5.4 ft, on Monday.

A live NOAA gauge measures the water here, and predictions are calculated from this station's own records. It was established in 1955. The nearest other station is Chatham, 2 mi away, where high tide comes about 8 min later. For tidal currents, see Stage Harbor, west of Morris Island.
