If you plan to swim at Popham Beach State Park in Phippsburg during the remainder of the summer, you should be extra careful.
There will be no lifeguards on duty starting on Monday.
If you go to the beach, you will swim at your own risk until next summer.
Officials remind you to be familiar with the tides as well as the forecast before you head out.
You can bring your pets on the beach starting Oct. 1.
