The series "The Summer I Turned Pretty" is set in the fictional town of Cousins Beach, which is inspired by several East Coast beach areas including Cape Cod, Martha's Vineyard, the Hamptons, and Nags Head. However, the actual filming took place primarily in and around Wilmington, North Carolina. Specific nearby beaches like Carolina Beach, Kure Beach, Wrightsville Beach, and locations such as the Cape Fear Country Club and Porters Neck Plantation were used for the production. The Fisher family beach house scenes were filmed on a private golf course community in Wilmington, designed to evoke a New England Cape Cod vibe with cedar shingle-style houses and hydrangea landscaping to match the book's setting aesthetic.
