About these predictions

Predictions for Block Island (Old Harbor) are computed from NOAA CO-OPS harmonic constituents with Ebb's tide engine. They are astronomical predictions and do not include the effect of wind, pressure or river flow on water levels. Ebb is not a navigation product. Use NOAA Tides & Currents for navigation.
