Plan around the tide at St. Augustine
No window of 30 minutes or more below 1.0 ft over the next 7 days in daylight. Try a higher level.
A falling tide uncovers sand bars and tide pools first; plan to be back before the water rises past the level you chose. Not for navigation.
Station St. Augustine Beach (NOAA 8720587). Predicted astronomical tide: wind, river flow and storms can move the real water by a foot or more. 5.0 ft is the average daily range here.
Published by Radif Partners · How the tides are computed · predictions downloaded October 13, 2026
Tide times for St. Augustine come from the National Ocean Service prediction for station 8720587, St. Augustine Beach. The tide here is semidiurnal: two highs and two lows of similar height every day, about six hours and a quarter apart, with an average daily range of 5.0 ft. Around the new and full moon the range grows to about 6.3 ft on one day in ten, and at the quarter moons it shrinks to 3.8 ft. Heights are in feet above Mean Lower Low Water, the zero of nautical charts, so a negative number is water below that zero: 177 of the 457 days from October 1, 2026 to December 31, 2027 have one, down to -1.2 ft on January 23, 2027. The highest predicted tide of that period is 6.5 ft on November 25, 2026. Clock times are Eastern Time, daylight saving time included.
Ocean beach and the old city's waterfront
St. Augustine Beach averages 5.0 ft from low to high, 6.3 ft on spring tides. The historic city itself faces the Matanzas River and the inlet, not the ocean: NOAA predicts the city dock from Fernandina Beach with high water 20 minutes earlier and three quarters of the height. The seawall along the bayfront and the Bridge of Lions see a smaller swing than the beach.
Two inlets, one river
The Matanzas River runs behind Anastasia Island between two inlets, St. Augustine Inlet to the north and Matanzas Inlet to the south, and NOAA keeps several reference stations along it, at State Road 312, Crescent Beach and the Matanzas Inlet bridge, plus Vilano Beach on the Tolomato to the north. Fort Matanzas, near the southern inlet, is predicted from Fernandina with high water 3 minutes later but low water 49 minutes later, a sign of how slowly the river drains. Boaters on the waterway meet the strongest current near the inlets.
Low tide on the beach
At low tide the coquina-tinted sand of the beach widens, and at the north end the inlet's shoals appear. Driving is permitted on some St. Johns County beaches, and drivers have to respect the tide line; check the county's rules before driving onto the sand. The lowest low predicted this period is -1.2 ft, on January 23, 2027. For the coast to the south, see Daytona Beach.
