No one was seriously injured, and lifeguards treated the stings with vinegar.
A county spokesman said 257 stings were reported Saturday and 149 occurred on Sunday.
The swarm is actually not something new for the area, said Volusia County Beach Safety Captain Tammy Marris. She said the county beaches see this size of a swarm about a dozen times a year.
“Jellyfish and anything in the water are at the mercy of the current and the winds,” Marris told USA TODAY Network.
“It could be thousands. It’s hard to see them in the water right now. All you can see are the ones on shore,” Marris told Reuters.
The most recent jellyfish swarm arrived Friday, with the majority along New Smyrna Beach, she said.
Volusia County Beaches officials raised purple and yellow flags along the beaches due to the “increased marine pests,” says the county’s Facebook page.
It appears the jellyfish have been carried back out to the ocean. There were only four reports of jellyfish stings on Monday, Marris said.

Surfer Jerry Phillips told Orlando’s WESH-TV that he was standing in the ocean with his daughter when he was stung.
“I think the tentacles wrapped all the way around my leg and really stung me,” he told the station. “I did scream a little bit.”
“They were all over and all in multiple sizes,” beachgoer Michelle Craycraft told WFTV.
Jellyfish sting with their tentacles. Although the stings generally are not severe, in rare cases, they can be life-threatening, according to the National Science Foundatio
Volusia County is in east central Florida and includes the Dayton Beach area.
