About this station
NOAA builds the predictions for Mackay River (ICWW), Buttermilk Sound from the Fort Pulaski, Savannah River Entrance station: high tides about the same height, 58 min later; low tides about 1.09× the height, 83 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.
