About this station
NOAA builds the predictions for Big Coppitt Key, northeast side, Waltz Key Basin from the KEY WEST station: high tides about 0.84× the height, 261 min later; low tides about 0.33× the height, 414 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.
