If you aren’t looking specifically for tuna there are some fun options. I used to live in palm beach county. I generally fished from Jupiter down to singer island. Mostly just walked the beach with a 7-8’ rod and fished poppers for lots of stuff - jacks, tarpon, snook, sharks, mackerel. Popping around sea walls and docks you can catch snook and big jacks. Throwing poppers into mangroves from a kayak or boat will yield similar results with the occasional redfish the further north you go. Never did any popping offshore though. Hoping to move back to south Florida in the not too distant future. I miss it! Good luck out there!
