About the tides at South Ashley Bridge
South Ashley Bridge has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The pattern follows the reference station at Charleston, Cooper River Entrance. With a mean range of about 5.3 ft, the shoreline here changes a lot between high and low water. From the average lower low to the average higher high, the difference is 5.8 ft. Over the next two weeks the biggest daily range, 7.0 ft, comes on October 28, and the smallest, 4.0 ft, today. Looking a year ahead, predictions peak at 7.0 ft on October 1 and bottom out at −1.5 ft on January 23.
Tides here are worked out from the reference station at Charleston, Cooper River Entrance, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. NOAA measured the tide here from 1975 to 1977 to set up these predictions. The nearest other station is Wappoo Creek, 1 mi away, where high tide comes about 18 min later. For tidal currents, see Ashley River Memorial Bridge, Highway 17.
Predictions are based on Charleston, Cooper River Entrance.
