About this station
NOAA builds the predictions for Halfmoon Island, highway bridge from the Fernandina Beach, Amelia River station: high tides about 0.70× the height, 120 min later; low tides about 1.05× the height, 159 min later.
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.
