I would look further south for both. Aransas bay, Laguna Madre for Bay and Port Aransas, Port Mansfield for offshore. Offshore you can still catch red snapper, Kings, cobia, sharks. I can't remember if the shimp boats will be out then but if so blackfin may be around. If you want a yellowfin trip I would look at Venice, La. Good luck!
