About this station
NOAA builds the predictions for Cosgrove Bridge from the CHARLESTON (Customhouse Wharf) station: high tides about 1.07× the height, 25 min later; low tides about 1.05× the height, 17 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.
