About the tides at Block Island

Block Island has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The pattern follows the reference station at Sitka. The range is large, about 9.4 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time.

Block Island is a subordinate station. NOAA predicts its tides by adjusting Sitka: highs come about 7 min and lows about 2 min later than there. The nearest other station is Natalia Point, 4 mi away, where high tide comes about 12 min earlier. For tidal currents, see Tlevak Narrows, Turn Point, east of.

Predictions are based on Sitka.
