About the tides at Johns Island
Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.9 ft. The pattern follows the reference station at Charleston, Cooper River Entrance. The range is large, about 6.9 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is larger than most South Carolina stations on this site. From the average lower low to the average higher high, the difference is 7.4 ft. The next spring tides peak on October 27, with a range of 9.0 ft. Neap tides follow today, when the range shrinks to 5.4 ft. In the next 12 months the highest predicted tide here is 9.0 ft on October 1, and the lowest is −1.7 ft on January 23.
Johns Island is a subordinate station. NOAA predicts its tides by adjusting Charleston, Cooper River Entrance: highs come about 103 min and lows about 60 min later than there. NOAA measured the tide here from 1977 to 1978 to set up these predictions. The nearest other station is Hollywood, 3 mi away, where high tide comes about 8 min later. For tidal currents, see Goshen Point, SE of, Wadmalaw River.
Predictions are based on Charleston, Cooper River Entrance.
