Newcomb Hollow Beach in Wellfleet was closed twice Wednesday for shark sightings, officials said.

The Cape Cod beach was first closed to swimming for an hour after a sighting at 11 a.m., said Suzanne Thomas, Wellfleet beach administrator. The water was closed again for an hour at 1:30 p.m., she said.

This is the second day in a row that Newcomb Hollow Beach has been closed because of shark sightings. Newcomb Hollow Beach was closed Tuesday afternoon after a State Police helicopter observed a great white shark near swimmers.

South Beach on Martha’s Vineyard was also closed to swimming Tuesday because of a shark sighting.
