A great white shark sighting first closed Crane Beach in Ipswich on Tuesday when a police officer on a boat spotted a shark in about five to seven feet of water. Now the Trustees of Reservations says Crane Beach will be closed for swimming until at least Monday after consulting with biologists and law enforcement.

People are not allowed to swim at Crane Beach in Ipswich through the end of September due to the number of sharks.

Crane Beach will remain closed to swimming through Sept. 30 due to the continued presence of great white sharks.

We will continue to reassess and will reopen for swimming as soon as shark activity in the area dissipates enough to be deemed safe,” said Christopher Moore, property director for Crane Beach.

A popular Massachusetts beach will remain closed to swimming through the end of September due to the presence of great white sharks in the water near the shoreline. Crane Beach in the North Shore town of Ipswich will be off-limits to swimmers until at least Oct.
