Through Strait, Seawater and Gulf Stream

Fishermen and swimmers have been killed in the Pass' treacherous waters. The Gulf of Mexico-West Bay pass transitions vast volumes of seawater. The San Luis Pass physical oceanography is essentially contributed to the aggressive Gulf Stream and loop current, fluctuating tides in marginal sea, and marine sediment. The marginal sea's ocean circulation is periodically redefining the coastal continental shelf subsequently reciprocating uncertainties of continental margin at Follet's Island and West Galveston Island.

The San Luis Pass-Vacek Toll Bridge spans San Luis Pass from Galveston County to Brazoria County.

Characteristics

Tide levels can vary by almost 2 feet in height, although the tidal effects seem more pronounced along straits than other barrier island zones. Water current dangers are prominent up to about one mile away from the pass along either island. A high amount of drownings occur in the vicinity of the San Luis Pass compared to other areas off of nearby beaches. Until June 2013, about 10 people drowned near San Luis pass on the Galveston side since 2001, and of those about 6 drowned there since 2007. The depth of the pass varies in depths to 40 feet deep.

Tides cause daily variations in topography, and occasionally, storms more drastically change the topography of the pass.
