About the tides at Halfmoon Island

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.5 ft. On a typical day the water moves about 3.7 ft between high and low. That is larger than most Florida stations on this site. Over the next two weeks the biggest daily range, 4.9 ft, comes on October 10, and the smallest, 3.9 ft, on Sunday.

Halfmoon Island is a subordinate station, so NOAA publishes only its high and low times and heights. The nearest other station is Cuno, 2 mi away, where high tide comes about 14 min later. For tidal currents, see Kingsley Creek, highway bridge.
