Because of how water diffusion works that's not really a concern... any viral particles entering the water from an infected individual would be instantly diluted to the point of not being a realistic risk. Also it's salt water which makes it even less likely the virus could survive.

The real risk is sewage pollution; if there's untreated pollution in the water it could (in theory) carry various things. This shouldn't be a huge concern these days though - untreated sewage SHOULDN'T be getting into beach water. And if it was, you'd have more than Covid to worry about if you went swimming in it.
