About these predictions

Predictions for Roche Harbor, San Juan Island are computed from NOAA CO-OPS harmonic constituents with Ebb's tide engine, using NOAA's published time and height offsets for this subordinate station. 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.
