Clavin said there are two main reasons for the sharks’ return: warm weather and the presence of more bait fish near the shoreline.
Clavin said beaches had been going through a purification process, with fewer swimmers and boats in the water for months because of the pandemic.
“But with that comes some other caveats, and one of them is more aquatic life and more of the feeders that draw these sharks in,” Clavin said.
There have already been 14 shark sightings in Hempstead this past week, with beaches closing again Saturday after multiple shark sightings.
The town has added extra lifeguards on surfboards and jet skis to keep beachgoers safe.
A college student caught a nearly 8-foot long bull shark in the waters off Lido Beach earlier this month.
