As the Fourth of July weekend approaches and beach crowds begin to swell, state and county officials are deploying high-tech tools to boost safety along Long Island’s shoreline.

This summer, drones will fly above state park beaches, aiding lifeguards in spotting potential dangers — including sharks — and even assisting swimmers in distress.

One drone can hover over the water before releasing a personal flotation device to a struggling swimmer — a potential lifesaver delivered straight from the sky.

“Drones are taking over everything nowadays,” said beachgoer Jason Yurcho. “So drop one in the water, throw me a little buoy — I think that would be nice.”

In total, 28 drones will be deployed across state beaches, primarily focused on shark detection. The move comes after a woman was bitten last week at Jones Beach, likely by a juvenile sand tiger shark. In response, both state and county agencies have increased their use of aerial surveillance.

Along with drone patrols, virtual reality headsets will be used at water safety outreach events to educate beachgoers about the dangers of rip currents. A larger drone capable of dropping flotation devices will be assigned to park police, providing another rapid-response option in emergencies.

“That is a great idea,” said beach visitor Prithivee Fow. “They have technology and they must use it — so that’s great.”

Nassau County is also stepping up its efforts. Earlier this week, officials announced additional shark surveillance drones, along with increased patrols by helicopters and boats.
