The first onshore shark sighting of the season occurred off the coast of Long Island on Monday, prompting renewed warnings from New York officials for beachgoers to remain vigilant as shark activity often peaks around the Fourth of July holiday.

Footage captured by Joanna L. Steidle shows a hammerhead shark swimming near a crowded beach. "I captured the 1st onshore shark sighting off the coast of New York for the season!" Steidle stated on X.

The sighting arrives as a significant heat wave impacts the eastern United States, with forecasts predicting heat indexes as high as 115 degrees Fahrenheit. Millions are expected to visit beaches seeking relief, leading authorities to issue safety advisories.

Officials are advising beachgoers to avoid areas with seals or schools of fish, steer clear of murky waters, and refrain from swimming at dawn, dusk, or night. Swimmers, surfers, and paddlers are also encouraged to stay in groups, remain close to shore, and heed the instructions of lifeguards and park staff.

While hammerhead sharks are not typically seen close to shore, they are known to inhabit the waters off Long Island and are observed more frequently during summer months as ocean temperatures rise. The species most commonly reported in the region is the smooth hammerhead.

The New York State Department of Environmental Conservation (DEC) has updated its guidance to minimize the risk of human-shark interactions, noting that 13 shark species are returning to the region as part of their annual migration from June through September. Sightings frequently intensify around the Fourth of July when sharks and their prey move nearer to the coast.

"Human-shark interactions are rare here, but DEC urges beachgoers and water enthusiasts to follow shark safety guidelines to reduce risk and help keep New Yorkers safe this summer," said Martin Gary, DEC Director of Marine Resources.

New York recorded one confirmed unprovoked shark bite in 2025, a minor incident on June 27 at Jones Beach State Park. Despite this, shark sightings were frequent throughout the summer, with numerous encounters reported off Long Island and New York City beaches. This marks a decrease from heightened activity in 2022 and 2023.

To enhance safety, state officials have significantly expanded shark surveillance efforts. Lifeguards, Park Police, and park staff are utilizing drones to monitor the water for sharks and attractants like large schools of fish. The number of certified drone operators across Long Island State Parks has grown, with additional operators expected to complete certification by the Fourth of July. The fleet of drones used during peak beach season has also increased.

New York Governor Kathy Hochul emphasized preparedness, stating, "As summer approaches, New York State is preparing to safely welcome millions of visitors to our Long Island State Park beaches. We continue to improve our surveillance capabilities to monitor for dangerous conditions and help protect beachgoers. I encourage all visitors to remain alert and adhere to the guidance of lifeguards and park staff when visiting the beach."
