About the tides at Fort Sumter

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 (Customhouse Wharf). The average range is about 4.9 ft. Spring tides add a little more at both ends. The next spring tides peak today, with a range of 6.2 ft. Neap tides follow on Sunday, when the range shrinks to 5.3 ft.

Fort Sumter is a subordinate station. NOAA predicts its tides by adjusting CHARLESTON (Customhouse Wharf): highs come about 2 min later and lows about 1 min earlier than there. NOAA measured the tide here from 1976 to 1977 to set up these predictions. The nearest other station is Fort Johnson, 1 mi away, where high tide comes about 7 min earlier. For tidal currents, see Charleston Harbor (off Fort Sumter).

Predictions are based on CHARLESTON (Customhouse Wharf).
