YORK – York Beach was reopened Thursday following a closure due to shark sightings, police said.

All public beaches in York were closed to swimming Wednesday after a pair of shark sightings within 24 hours. The first was made at Libby’s Oceanside Camp on Tuesday night, and the second was made Wednesday by a lifeguard.

Sharks sightings are extremely rare in Maine. But Wells Beach had to shut down earlier this month because of sharks near shore.

It is believed that the sharks are being drawn near the beaches in part because of unusually high water temperatures this summer.
