About this station
NOAA builds the predictions for Johnston Key, southwest end, Turkey Basin from the KEY WEST station: high tides about 1.10× the height, 206 min later; low tides about 0.50× the height, 338 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.
