Brazoria was great, plenty of room and you can safely get high enough for the high tide. Just check the tides for an unusual high. We were there in Feb so it was a little cold with the wind.

Brazoria County Beach is a good option. I like it more than Padre. It's hard-packed sand and there's plenty of room. No amenities. The town of Surfside Beach abuts it, as well as the paid town beach. There are places to eat (Jetty Shack has good burgers), Sharkies is a decent local bar, and there are other options. I spend time every winter at Brazoria. Just left a couple of weeks ago. Plan to go back again soon. There's also the intercoastal waterway area at the Brazoria end of Galveston Island. You drive down on the beach near the toll booth. Soft sand, tricky, but beautiful. Plan on mosquitoes at both beaches.

All of those are great options I personally favor brazoria and crystal but I've been there recently and had no issues
