About this station
State Road 312, Matanzas 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.
Two coasts, two personalities: modest 2 to 4 ft semidiurnal ranges on the Atlantic side, mixed tides on the Gulf side, and king tides that flood streets on calm, sunny days.
