About the tides at Back River Reservoir

Expect two roughly equal high tides a day at Back River Reservoir, each arriving about 50 minutes later than the day before. The pattern follows the reference station at Charleston, Cooper River Entrance. Water here rises and falls only about 0.4 ft on an average day. A strong onshore wind can push levels above the prediction. That is smaller than most South Carolina stations on this site. Over the next two weeks the biggest daily range, 1.2 ft, comes on October 28, and the smallest, −0.3 ft, today. Looking a year ahead, predictions peak at 1.2 ft on October 27 and bottom out at −1.2 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. The nearest other station is General Dynamics Pier, 1 mi away, where high tide comes about 4 h 4 m earlier. For tidal currents, see Back River entrance.

Predictions are based on Charleston, Cooper River Entrance.
