About the tides at Marshall Hall

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.2 ft. The pattern follows the reference station at Washington, Potomac River. The average range is about 2.1 ft. Spring tides add a little more at both ends. That is larger than most Maryland stations on this site. The next spring tides peak on October 27, with a range of 2.7 ft. Neap tides follow today, when the range shrinks to 1.6 ft. In the next 12 months the highest predicted tide here is 3.0 ft on June 5, and the lowest is −0.7 ft on January 24.

Marshall Hall is a subordinate station. NOAA predicts its tides by adjusting Washington, Potomac River: highs come about 10 min later and lows about 55 min earlier than there. The nearest other station is Indian Head, 7 mi away, where high tide comes about 24 min earlier. For tidal currents, see Hallowing Point.

Predictions are based on Washington, Potomac River.
