Biscayne in June: what the park service says
Hurricane season starts on June 1 and lasts until November 30, and summer here is hot and humid with scattered thunderstorms in the afternoons. Paddlers can put in at Convoy Point, whose canoe and kayak launch is open daily from 7 AM to 5:30 PM, and snorkeling in the seagrass near shore is allowed, though the reefs are a boat ride of more than ten miles. The park's safety page lists jellyfish, stingrays, sharks and the American crocodile as the animals to watch for, especially near mangroves and sandy banks. It also warns that the scent of bait or a fresh catch, or the sound of splashing, can draw sharks and crocodiles in.
