About this station
NOAA builds the predictions for Champney Island, South Altamaha River from the Fort Pulaski, Savannah River Entrance station: high tides about 0.76× the height, 70 min later; low tides about 0.77× the height, 153 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.
