About the tides at Cornfield Harbor

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.1 ft. The pattern follows the reference station at Washington, Potomac River. The mean range is small, about 1.2 ft, so wind and pressure can matter as much as the tide itself. The next spring tides peak on October 27, with a range of 1.6 ft. Neap tides follow today, when the range shrinks to 1.0 ft. In the next 12 months the highest predicted tide here is 1.7 ft on June 5, and the lowest is −0.4 ft on January 24.

Cornfield Harbor is a subordinate station. NOAA predicts its tides by adjusting Washington, Potomac River: highs come about 376 min and lows about 455 min earlier than there. The nearest other station is Point Lookout, 3 mi away, where high tide comes about 41 min earlier. For tidal currents, see Cornfield Point, midchannel.

Predictions are based on Washington, Potomac River.
