Two more swimmers were apparently attacked by sharks off Long Island on Tuesday — a day after a 15-year-old surfer was bitten at a nearby beach.

Tuesday’s reported attacks both happened just before 2 p.m. about 60 miles apart from each other.

A 47-year-old man was enjoying the water at Quogue Village Beach in the Hamptons when he felt an apparent bite to his right knee, Quogue police said.

He told authorities that he did not see a shark.

Shortly after, a 49-year-old man reported that his hand was bitten while swimming at Fire Island Pines Beach — not far from where a 15-year-old boy was bitten while surfing a day earlier.

The teen was nipped on left heel and toes around 5:20 p.m. on Monday, Suffolk County police said. He swam to shore in Kismet and was aided by a good Samaritan before he was treated at a local hospital for puncture wounds.

Earlier on Tuesday, Robert Moses Beach delayed opening the water to swimmers after a school of about 50 sand sharks were spotted about 200 yards offshore around 8 a.m.

Long Island Parks Regional Director George Gorman told The Post staff monitored the school with surveillance drones for about 90 minutes before they determined the beaches were safe and opened for the day around 9:30 a.m.

The beach was closed once more after a possible shark sighting, but officials determined it was a dolphin.

On Monday, a 15-year-old girl was possibly bit while swimming off Robert Moses Beach around 1:45 p.m. 

She was treated for small puncture wounds on her left leg. At the time, lifeguards searched for sharks using drones but did not locate any.

“She didn’t see what bit her, the lifeguards didn’t know what bit her, the drone operator checked the area, we didn’t see,” Gorman said. “So we can’t definitively say what bit her.”

Authorities have confirmed that the teenage surfer bit off Fire Island on Monday was attacked by some kind of shark — the first confirmed shark attack of 2023, after an alarming six people reported being bitten off Long Island in 2022.

In response to the surge in attacks, Gov. Kathy Hochul announced in May that 10 new shark-spotting drones had been purchased so Long Island police and park officials can monitor the beaches from the air.

Parks officials have used the technology to scout out the waters for sharks before revelers flock to the beaches.
