New York officials have temporarily closed sections of several beaches after multiple shark sightings and elevated bacteria levels raised safety concerns just days before the Fourth of July holiday weekend.
The warnings come as millions of Americans are expected to visit beaches for Independence Day celebrations, with Long Island and New York City’s shoreline among the country’s busiest summer destinations.
Nine-Foot Shark Spotted Off Long Island Coast
One of the latest incidents occurred Thursday morning when a shark estimated to be about nine feet long was seen near Point Lookout in the Town of Hempstead, Nassau County.
Officials responded by raising red warning flags along the beach and neighboring shorelines, advising swimmers to leave the water while safety protocols were activated.
The Town of Hempstead’s Shark Patrol, supported by drones and patrol boats, has continued monitoring the area following the sighting.
Swimming Suspended Under Shark Response Protocol
Authorities said the shark appeared in one of the busiest sections of the beach, with both lifeguards and visitors reporting the sighting.
In accordance with local shark safety procedures, swimming was suspended for one hour along approximately one mile of coastline on either side of where the animal was observed, allowing officials to monitor whether it remained in the area.
Rockaway Beach Reports Multiple Shark Encounters
The New York City Parks Department also reported repeated shark sightings near Rockaway Beach, warning that temporary closures could continue if additional marine activity is detected.
Officials said several bull sharks were observed close to shore, with reports indicating at least one sighting every hour after the initial detection.
Beachgoers have been advised to closely follow instructions issued by lifeguards and park personnel throughout the holiday period.
Seasonal Migration Brings Sharks Closer to Shore
Marine experts note that shark migration along the Atlantic coast typically takes place between June and September as ocean temperatures increase.
Sightings often become more frequent around the Fourth of July, when sharks follow schools of bait fish, including bunker fish, into shallower coastal waters, increasing the likelihood of encounters near popular swimming areas.
Officials Issue Water Safety Advice
In response to the heightened shark activity, New York authorities have encouraged beach visitors to avoid entering waters where seals, schools of fish or diving seabirds are present, as these can indicate nearby predators.
Officials also recommend avoiding swimming in murky water or during dawn, dusk and nighttime hours, when sharks are generally more active.
Swimmers, surfers and paddleboard users have additionally been advised to stay in groups, remain close to shore and immediately follow any directions from lifeguards.
Earlier Hammerhead Shark Sighting Marked Start of Season
The latest incidents follow the season’s first confirmed nearshore shark sighting earlier this week off Long Island.
Photographer Joanna L. Steidle captured aerial footage showing a hammerhead shark swimming relatively close to a crowded beach before sharing the images online, highlighting the beginning of New York’s annual shark season.
Bacteria Contamination Closes Additional Beaches
Sharks are not the only concern affecting beach access this week. Several beaches in Nassau County and Suffolk County have also been closed to swimmers after routine testing detected bacteria levels exceeding New York State safety standards.
The Nassau County Department of Health ordered temporary swimming closures at Biltmore Beach Club and Philip Healey Beach in Massapequa, while Tides Beach in Rocky Point and Ronkonkoma Beach in Ronkonkoma were also affected by similar advisories.
Heavy Rainfall Linked to Elevated Bacteria Levels
Health officials said recent heavy rainfall contributed to increased stormwater runoff, which can carry bacteria into recreational waters.
Exposure to contaminated water may cause gastrointestinal illness as well as infections affecting the eyes, ears, nose and throat.
The affected beaches will remain closed to swimming until follow-up testing confirms that water quality has returned to levels considered safe for public use.
