How old is old enough to take baby to the beach?

We wna take our lil guy to the beach for the first time (we live in Florida) ☀️🌊 
He's 10 weeks old but he's a big strong guy. I'm already prepared for the basics like sunscreen, keeping the sun off of him, keeping him cool, baby powder to get the sand off, etc..
Probably not going to get him in the water. Maybe just let him touch it with his lil fat legs ☺️ He doesn't even have a swimming suit yet nor the lil swimmers diapers. 
Thank u! XO
