About this station
NOAA builds the predictions for Nassau River Entrance from the Fernandina Beach, Amelia River station: high tides about 0.86× the height, 18 min earlier; low tides about the same height, 41 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.
