About this station
Halfmoon Reef, Halfmoon River is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
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.
