North Carolina and Paris: The Final Two Settings

While the fictional Cousins Beach remains the spiritual home of the series, the final season's plot required a major change of scenery, taking the production crew across the Atlantic.

• North Carolina, USA: As with previous seasons, much of the "Cousins Beach" setting was filmed in Wilmington and the surrounding coastal areas of North Carolina. This includes the iconic beach house, the local town, and the familiar haunts of Belly, Conrad, and Jeremiah.
• Paris, France: A significant portion of Season 3 was filmed in Paris, France, from approximately September through November. This international filming location is a direct nod to the plot of the third novel, where a major turning point in Belly's relationship with one of the brothers occurs in the City of Love. This addition adds a fresh, new visual element to the series.

The entire filming process for the final season spanned approximately five to six months, running from March to August 2025. This extended schedule was necessary to capture the full scope of the 11-episode season and the various locations.

What to Expect from The Summer I Turned Pretty Season 3 Plot

Season 3 is based on Jenny Han's third novel, "We'll Always Have Summer," and promises to deliver the ultimate resolution to the love triangle. The central theme of this season is finality, as Belly is forced to confront her deepest feelings and commit to one of the brothers.

Key Plot Points and New Characters

The final book's storyline is known for its time jump and the introduction of new dynamics that test the relationships established in the first two seasons. Fans should prepare for a significant shift in the emotional landscape of the show.

• The Ultimate Choice: Belly’s journey culminates in a decision that will define her future. The pressure to choose between the steady, supportive love of Jeremiah and the intense, complicated connection with Conrad is the driving force.
• A Feature-Length Future?: Intriguingly, following the series finale on September 17, 2025, a feature-length film was announced. While details are scarce, this suggests that the world of Cousins Beach may continue beyond the main series, perhaps offering an even deeper look into the characters' lives post-finale.
• New Faces: The final season introduces new characters, including Isabella Briggs and Kristen Connolly, who are joining the ensemble cast. These new additions are expected to play pivotal roles in the final chapters, potentially adding new romantic interests or complications for the main characters. Early fan speculation suggests one new character, "Denise," might be a forced love interest for Jeremiah, creating further tension in the 'Jelly' storyline.

The 11-episode schedule, weekly drops, and the promise of a definitive ending mean that every Wednesday from July 16 to September 17, 2025, will be a major event for the dedicated fanbase. Be sure to mark your calendars for the final summer at Cousins Beach!
