Several popular beaches on Long Island, New York, have been temporarily closed or issued swimming advisories due to multiple shark sightings in the days leading up to the Fourth of July holiday weekend. The closures affect beaches that attract millions of visitors annually.

On Thursday, a nine-foot shark was spotted off the coast of Point Lookout in Hempstead, Nassau County. The New York City Parks Department also reported multiple shark sightings near Rockaway Beach, prompting warnings of potential intermittent closures. Beachgoers have been instructed to follow the guidance of lifeguards and on-site personnel.

In response to the Point Lookout sighting around 10:30 a.m., officials immediately raised red flags and suspended swimming for one hour along approximately a one-mile stretch of coastline in both directions from the sighting location, as per the Town of Hempstead's shark response protocol. Drones and patrol boats have been deployed to monitor local waters.

Later, a swarm of bull sharks was reported close to the shore at Rockaway Beach. Officials noted that sharks had been observed in the surf for several hours, with at least one sighting occurring hourly.

Separately, Biltmore Beach Club in Massapequa, Tides Beach in Rocky Point, and Ronkonkoma Beach in Ronkonkoma have been closed to swimming due to elevated bacteria levels above state safety standards, according to the Nassau County Department of Health. Health officials cautioned that swimming in contaminated water can lead to gastrointestinal illnesses and infections of the eyes, ears, nose, and throat. These beaches will remain closed until subsequent tests confirm that bacteria levels have returned to acceptable limits.

These beach closures occur as millions of Americans prepare to visit coastal areas for the holiday, highlighting a shared presence between beachgoers and marine life in the water.
