About the tides at Fort Johnson

Fort Johnson has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. 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 6.1 ft. Neap tides follow on Sunday, when the range shrinks to 5.3 ft.

Fort Johnson is a subordinate station. NOAA predicts its tides by adjusting CHARLESTON (Customhouse Wharf): highs come about 5 min and lows about 2 min earlier than there. The nearest other station is Fort Sumter, 1 mi away, where high tide comes about 7 min later. For tidal currents, see South Chan., 0.4 mi. NW of Ft. Johnson.

Predictions are based on CHARLESTON (Customhouse Wharf).
