The Summer I Turned Pretty Season 3: The FINAL Release Date, 11 Episodes, And The Love Triangle’s Inevitable End
The wait is officially over. As of today, December 19, 2025, the highly anticipated release date for the third and final season of *The Summer I Turned Pretty* (TSITP) has been confirmed by Prime Video. Fans can mark their calendars for the emotional conclusion to Belly Conklin’s journey, which will resolve the intense, years-long love triangle with the Fisher brothers, Conrad and Jeremiah. This final chapter promises to be the biggest and most dramatic yet, adapting the third and final novel in Jenny Han’s trilogy, *We’ll Always Have Summer*. The show’s creator, Jenny Han, has confirmed that the final season is "supersized" to give the beloved characters the send-off they deserve.
The third season will not only determine Belly's ultimate romantic choice but will also explore the characters' lives after high school, dealing with college, new relationships, and the lasting legacy of Susannah Fisher’s passing. With 11 episodes—three more than Season 2—the show has ample time to explore the complex emotional fallout and deliver a satisfying, if heartbreaking, conclusion for some.
The Official TSITP Season 3 Release Date and Episode Schedule
The final summer at Cousins Beach is set to begin in the middle of next year. The official premiere date for *The Summer I Turned Pretty* Season 3 is Wednesday, July 16, 2025.

Plot Leaks and The Inevitable Conclusion of the Love Triangle
The third season is based on the third novel in the trilogy, *We’ll Always Have Summer*. The book’s plot is a significant jump in time and emotional stakes, and while the show has made changes before, the core conflict is expected to remain.
The Central Conflict: Belly and Jeremiah’s Engagement
Season 3 is set to pick up with Belly and Jeremiah as a couple, navigating their relationship while attending college. The central, shocking event of the final book is Belly and Jeremiah's decision to get married. This engagement, which occurs while they are still young, is a desperate attempt by Belly to hold onto the past and the feeling of family she shares with the Fishers, especially in the wake of Susannah’s death.
Conrad Fisher, who is away at Stanford, is predictably against the marriage, believing it to be a mistake driven by grief and immaturity. His intervention and attempts to stop the wedding form the major dramatic tension of the season, forcing Belly to confront her true feelings and the reality of her relationship with both brothers. The setting of the wedding, which is often at the beloved Cousins Beach house, raises the stakes even higher.
Jenny Han’s Vision: Team Conrad vs. Team Jeremiah
The core question since Season 1 has been: Who will Belly choose? The books provide a definitive answer: Belly ultimately chooses Conrad. Years after the initial drama of the failed wedding, the final book sees a 23-year-old Belly Conklin marrying Conrad Fisher back at Cousins Beach.
Show creator and author Jenny Han has been vocal about the inevitability of this ending, even while acknowledging the strong "Team Jeremiah" fanbase. The show's narrative, much like the books, has been subtly steering Belly toward Conrad, often portraying their connection as the deeper, more soulmate-like bond, even amidst their intense pain and miscommunication.
The supersized 11-episode season will allow the series to fully explore the complexities of the love triangle, not just as a romantic choice, but as a journey of self-discovery for Belly. She must learn to love herself and let go of the shame and attachment to the past before she can truly commit to a healthy future. The final episodes are expected to explore a significant time jump, mirroring the book's epilogue, to show Belly and Conrad finally finding their way back to each other, years after the dust settles from the Jeremiah wedding debacle.
The season will be a rollercoaster of emotions, featuring key entities like Brown University (where Conrad attends), the fictional Cousins Beach town, and the emotional weight of the Conklin family and Fisher family dynamics. Fans should prepare for a bittersweet conclusion that honors the spirit of the books while providing a fresh, definitive resolution to the most talked-about love triangle on television. The final summer is coming, and it promises to be unforgettable.
