Tidal Variances


As natural phenomena, tides resulting from gravitational influence are not swift events, but rather gradual predictable occurrences. At Sebastian Inlet, annual tidal variances can exceed 4.5 ft. (1.5 m);
however, during certain times of the year, daily tidal variance can be less than 0.5 ft. (15 cm). Within intracostal waters, wind driven tides can have a significant influence vis--vis gravitational influence of celestial bodies.

The low to high water extremes provide a formidable challenge in establishing appropriate elevation along open shorelines.
