The third season will pick up on the dramatic events of the Season 2 finale, where Belly (Lola Tung) makes a definitive choice between the two brothers, a decision that will ripple through the final summer at Cousins Beach.

The story will largely follow the events of Jenny Han’s final book, We'll Always Have Summer, which sees the characters navigating college life, a surprising engagement, and the ultimate realization of who Belly is truly meant to be with. The central theme remains the enduring bond between the Conklin and Fisher families, even as the younger generation faces adulthood.

The Returning and Key Supporting Entities

The emotional weight of the final season will be carried not just by the central trio, but by the strong supporting cast who represent the two families involved in the generational drama:

• Steven Conklin (Sean Kaufman): Belly’s older brother, who has his own relationship drama and a close bond with the Fisher brothers.
• Laurel Park (Jackie Chung): Belly and Steven’s mother, whose friendship with Susannah Fisher is the foundation of the annual summer tradition.
• Susannah Fisher (Rachel Blanchard): Though her character's arc concluded in Season 2, her memory and influence on her sons and Belly will be a powerful entity throughout the final season.
• Taylor Jewel (Rain Spencer): Belly’s best friend, whose presence provides a grounding, comedic element to the intense love-triangle drama.
• Cousins Beach: More than just a location, the beach house is a central entity in the series, representing the magic, heartbreak, and nostalgia of their shared summers.

Fans are deeply divided between the "Bonrad" (Belly and Conrad) and "Jerebear" (Belly and Jeremiah) camps, and the 11-episode structure ensures that both sides of the love triangle will receive significant screen time before the definitive ending is revealed. The show is known for its incredible soundtrack, and viewers can expect a fresh set of Taylor Swift songs and other nostalgic summer anthems to accompany the final, dramatic plot points.

Why the Final Season Has 11 Episodes and What It Means for the Story

The decision to expand The Summer I Turned Pretty Season 3 to 11 episodes is a clear signal from showrunner Jenny Han that the story requires more time to fully adapt the complexities of the third book. This book, We'll Always Have Summer, is arguably the most dramatic and emotionally dense of the trilogy, covering a significant time jump and multiple major life events.

The extra episodes allow the series to explore several crucial LSI themes and plot points without rushing, including:

1. The College Years: The book covers Belly and Jeremiah's time together at Brown University, a major setting that contrasts with the carefree atmosphere of Cousins Beach. The 11 episodes will allow the show to properly establish this new environment and the challenges it presents to their relationship.
2. The Engagement and Fallout: A major plot point involves a premature engagement, which serves as a catalyst for the final confrontation between the three main characters. The expanded season ensures this emotional event and its fallout—the ultimate decision between the Fisher brothers—is given the weight it deserves.
3. Parental Entities: The relationships between Laurel Park and the Fisher family, as well as the personal arcs of characters like Steven Conklin, will have more room to develop, providing a richer, more topical authority to the series' conclusion.
4. A Satisfying Conclusion: With the series ending, the 11-episode count is a promise to the dedicated fanbase that the story will not be cut short. It guarantees a satisfying, well-paced conclusion to the journey of Belly Conklin, Conrad Fisher, and Jeremiah Fisher, ensuring that the series finale on Wednesday, September 17, 2025, feels earned and complete.

In summary, the final summer at Cousins Beach is on the horizon. With the two-episode premiere on July 16, 2025, and a consistent weekly release schedule every Wednesday at 3 a.m. ET on Prime Video, fans of the Jenny Han adaptation can prepare for a summer filled with intense romance, drama, and the long-awaited answer to the central question: will it be Conrad or Jeremiah?
