The majority of those stung were in Suffolk County at Robert Moses Beach Park in Babylon where thousands were spotted along the shoreline on Sunday, Sept. 4, according to George Gorman, of New York State Parks Department.
As of Tuesday, Sept. 6, there were 300 reported stings at Robert Moses alone, Gorman said.
Another 200 people were reported stung in Nassau County at Jones Beach, he added.
By Monday, the slimy stingers had moved about 100 yards offshore, so fewer swimmers were targets, Gorman said.
"It's normal for jellyfish to be in the area from mid-August to mid-September," he said. "But it was very unusual to see thousands this close to the shore."
None of the injuries were serious, but lines were reportedly out the doors at the beach medical clinics.
