Kind of, the beaches are not "closed" however the Access Point will be closed:
June 30 - July 11: Beaches close at 8 PM (Beach Curfew every night from 8 PM to 6 AM )
July 3 - July 7 (ending at 6 AM): No vehicles (including golf carts and ATVs) are permitted on the beach; they suggest you get a friend or taxi to drop you at the access way... Basically the beaches are open but only if you live on the beach or don't mind walking.
All this is from the Port Aransas Chamber of Commerce's Facebook page https://www.facebook.com/pachamberofcommerce/
Also this info applies to all Nueces County Beaches
Since carrying a kayak down the beach access road is impractical, Kimberly with the Port A. Chamber of Commerce recommended putting in at the Lighthouse Lakes Park at 2090 TX-361, Port Aransas, TX 78373 (coordinates 27°52'05.0"N 97°05'07.0"W ).
I just need a change of scenery, BAD.
