About the tides at Block Island (Old Harbor)
Block Island (Old Harbor) has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The average range is about 2.9 ft. Spring tides add a little more at both ends. From the average lower low to the average higher high, the difference is 3.2 ft. The next spring tides peak on Saturday, with a range of 3.9 ft. Neap tides follow on October 18, when the range shrinks to 1.6 ft. In the next 12 months the highest predicted tide here is 4.1 ft on July 4, and the lowest is −0.9 ft on January 23.
This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here from 1987 to 1989 to set up these predictions. The nearest other station is Southwest Point, 3 mi away, where high tide comes about 14 min later. For tidal currents, see Old Harbor Pt., 0.5 mile southeast of.
