About the tides at Colonial Beach

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.2 ft. The mean range is small, about 1.6 ft, so wind and pressure can matter as much as the tide itself. That is smaller than most Virginia stations on this site. From the average lower low to the average higher high, the difference is 1.9 ft. In the next 12 months the highest predicted tide here is 2.4 ft on September 2, and the lowest is −0.6 ft on January 23.

This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here from 1972 to 2010 to set up these predictions. The nearest other station is Dahlgren, 6 mi away, where high tide comes about 12 min later. For tidal currents, see Swan Point.
