About the tides at Harbor River Bridge

Harbor River 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 Fort Pulaski, Savannah River Entrance. With a mean range of about 6.1 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 6.7 ft. Over the next two weeks the biggest daily range, 7.2 ft, comes today, and the smallest, 4.2 ft, on October 19. Looking a year ahead, predictions peak at 7.8 ft on October 27 and bottom out at −1.7 ft on January 23.

Tides here are worked out from the reference station at Fort Pulaski, Savannah 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 1974 to 1976 to set up these predictions. The nearest other station is Johnson Creek Bridge, 1 mi away. For tidal currents, see Egg Bank, St. Helena Sound.

Predictions are based on Fort Pulaski, Savannah River Entrance.
