About this station
NOAA builds the predictions for Grassy Key, south side, Hawk Channel from the KEY WEST station: high tides about 1.22× the height, 52 min earlier; low tides about 0.71× the height, 26 min earlier.
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.
