About the tides at St. Marks River Entrance

St. Marks River Entrance has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. On a typical day the water moves about 2.6 ft between high and low. That is larger than most Florida stations on this site. From the average lower low to the average higher high, the difference is 3.5 ft. Over the next two weeks the biggest daily range, 4.0 ft, comes on Monday, and the smallest, 1.9 ft, on October 19. Looking a year ahead, predictions peak at 4.4 ft on August 2 and bottom out at −1.5 ft on December 24.

Predictions for St. Marks River Entrance come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here from 1970 to 1977 to set up these predictions. The nearest other station is Port Leon, 4 mi away, where high tide comes about 1 h 8 m later. For tidal currents, see St. Marks River approach.
