About this station
NOAA builds the predictions for Harbor River entrance from the CHARLESTON (Customhouse Wharf) station: high tides about 0.93× the height, 3 min later; low tides about 0.95× the height, 36 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.
