Even during the warmest summer months, the ocean temperature is barely above . Falling out of a boat into the water anytime between September and April can be dangerous, if not fatal, depending on the time of year. Swimming is enjoyed usually in inlets and coves where the water temperature is slightly higher, and off the pier or docks. Like most islands in the area, Chebeague has as much rocky cliffs for a shoreline as beaches. The Niblic beach by the boatyard and Deer Point by Chandler's Cove are popular beaches for their soft stretch of sand. On a clear day at Deer Point, one can see Mount Washington in New Hampshire. When the sun goes down, temperatures can drop drastically and, even on the warmest summer days, nights are often very cool and can require long sleeves and pants and even a fire in the fireplace. Winters can be brutal, and usually by September, most of the non-year-round residents are packed up and gone.
