About the tides at Nassau River Entrance

Nassau River Entrance 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 Fernandina Beach, Amelia River. The range is large, about 5.2 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is larger than most Florida stations on this site. From the average lower low to the average higher high, the difference is 5.7 ft. The next spring tides peak on October 26, with a range of 6.5 ft. Neap tides follow on Monday, when the range shrinks to 3.5 ft. In the next 12 months the highest predicted tide here is 6.7 ft on October 27, and the lowest is −1.5 ft on January 23.

Nassau River Entrance is a subordinate station. NOAA predicts its tides by adjusting Fernandina Beach, Amelia River: highs come about 18 min earlier and lows about 41 min later than there. NOAA measured the tide here in 1978 to set up these predictions. The nearest other station is Sawpit Creek entrance, 0.4 mi away. For tidal currents, see Midsound, 1 mi. N of Sawpit Creek entrance.

Predictions are based on Fernandina Beach, Amelia River.
