About this station
NOAA builds the predictions for Big Spanish Key from the KEY WEST station: high tides about 1.97× the height, 199 min later; low tides about 1.50× the height, 269 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.
