About this station
NOAA builds the predictions for Grahamville from the CHARLESTON (Customhouse Wharf) station: high tides about 0.20× the height, 497 min later; low tides about 0.58× the height, 512 min later.
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.
