About this station
NOAA builds the predictions for Fort Sumter from the CHARLESTON (Customhouse Wharf) station: high tides about 0.97× the height, 2 min later; low tides about 0.95× the height, 1 min earlier.
Georgia and the Carolinas run the biggest ranges on the Southeast coast — 7 to 10 ft through marsh creeks and barrier-island inlets that rearrange themselves with every storm.
