About the tides at Johnston Key

Johnston Key has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The mean range is small, about 1.8 ft, so wind and pressure can matter as much as the tide itself. The next spring tides peak today, with a range of 2.6 ft. Neap tides follow on October 8, when the range shrinks to 2.1 ft.

Johnston Key is a subordinate station, so NOAA publishes only its high and low times and heights. The nearest other station is Pumpkin Key, Bow Channel, 2 mi away, where high tide comes about 9 min earlier. For tidal currents, see Loggerhead Key, East of.
