Shark sightings closed the water at Ballston Beach in Truro, Nauset Beach in Orleans, Newcomb Hollow Beach in Wellfleet, and Coast Guard Beach in Eastham Monday, officials said.
A sighting a mile off Marconi Beach in Wellfleet also caused officials to prohibit beachgoers from venturing into deep waters.
Ballston Beach closed due to a shark sighting Monday morning and reopened at 8:30 a.m., the town of Truro said.
“The town of Truro would like to report a sighting of a great white shark at Ballston Beach on Tuesday, Aug. 13 at 7:35 a.m. The shark’s direction of travel is unknown,” the town said in a statement.
Nauset Beach in Orleans was closed to swimming from 10:50 a.m. to 11:50 a.m. after a shark was seen attacking a seal 50 feet offshore, according to a Nauset Beach employee and the Atlantic White Shark Conservancy Sharktivity app.
At around 11:20 a.m., two sharks were spotted a mile away from Marconi Beach in Wellfleet, according to the Sharktivity app.
“Wading only until further notice,” the app said. The restriction was lifted about an hour later, according to the app.
At around 2:10 p.m., Newcomb Hollow Beach in Wellfleet also closed, Wellfleet Beach Administrator Suzanne Thomas said. The beach was expected to be closed to swimming for one hour.
Coast Guard Beach in Eastham closed for the day at 4 p.m. after a shark was spotted 30 yards out by lifeguards, according to Sharktivity.
The latest closures meant that there have been a total of at least 36 on the Cape and Islands since Aug 1. Since July 1, beaches have closed more than 53 times after shark sightings.
