About Stone Harbor Beach
Stone Harbor is an upscale, family-oriented borough on Seven Mile Island in Cape May County, just south of Avalon. It's known for wide Atlantic beaches, a walkable downtown, and the Stone Harbor Bird Sanctuary. It draws families and summer-home owners looking for a quieter, refined stretch of the southern Jersey Shore. Swimming centers on the summer with guarded beaches. Water temperature follows the open Atlantic — cool and bracing in the 60s°F in June, warming through July into the low-to-mid 70s°F by August and early September, then cooling through the fall. Its southern location can mean slightly warmer peak-summer water. The beach faces open ocean, so the live conditions and safety flag above show today's picture.
