About the tides at South Dewees Island

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.7 ft. The pattern follows the reference station at Charleston, Cooper River Entrance. The average range is about 4.9 ft. Spring tides add a little more at both ends. From the average lower low to the average higher high, the difference is 5.5 ft. The next spring tides peak on October 25, with a range of 5.9 ft. Neap tides follow on Sunday, when the range shrinks to 3.7 ft. In the next 12 months the highest predicted tide here is 6.5 ft on October 1, and the lowest is −1.3 ft on January 23.

South Dewees Island is a subordinate station. NOAA predicts its tides by adjusting Charleston, Cooper River Entrance: highs come about 1 min and lows about 17 min earlier than there. NOAA measured the tide here from 1975 to 1977 to set up these predictions. The nearest other station is North Dewees Island, 2 mi away. For tidal currents, see Horlbeck Creek, 0.2 mile above entrance.

Predictions are based on Charleston, Cooper River Entrance.
