About this station
NOAA builds the predictions for Blount Island Bridge from the MAYPORT (BAR PILOT DOCK) station: high tides about 0.77× the height, 42 min later; low tides about 0.73× the height, 65 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.
