About this station
NOAA builds the predictions for Mayo Key, Big Spanish Channel from the KEY WEST station: high tides about 0.92× the height, 215 min later; low tides about 1.08× the height, 181 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.
