The final season of The Summer I Turned Pretty debuted on Prime Video on July 16, delivering an emotional return to Cousins Beach with a fresh batch of summer heartbreak, romance, and pivotal decisions. The third season, adapted from Jenny Han’s novel We’ll Always Have Summer, consists of 11 episodes—the longest in the series—marking a significant farewell for fans who’ve followed the story of Belly, Conrad, and Jeremiah since its 2022 premiere.
Prime Video released the first two episodes simultaneously on premiere day, with new episodes scheduled to roll out every Wednesday through September 17. This weekly release pattern mirrors the format used in previous seasons, keeping viewers engaged in the unfolding drama while building anticipation for the series’ final conclusion.
Set a year after the emotional events of Season 2, the new season finds Belly Conklin (played by Lola Tung) finishing her junior year of college. She’s on the cusp of adulthood, trying to balance her future aspirations with the weight of her past. The story resumes as she returns to Cousins Beach, the cherished summer retreat that has shaped her most transformative years.
The central love triangle—Belly, Jeremiah (Gavin Casalegno), and Conrad (Christopher Briney)—takes center stage again as the characters confront long-simmering feelings, broken trust, and looming choices. Belly is now engaged to Jeremiah, a decision that reflects a season of growth and reconciliation between the two after a period of separation. However, as she prepares to move forward with Jeremiah, her unresolved feelings for Conrad resurface, igniting new tension and introspection.
The opening episodes waste no time diving into emotional territory. Viewers learn that Jeremiah had a brief romantic encounter with another girl during his breakup with Belly, creating a wedge in their newly rekindled relationship. Despite the setback, they reconcile, and Jeremiah ultimately proposes—a bold move that Belly accepts. Meanwhile, Conrad remains on the sidelines, struggling with grief and his own lingering love for Belly. His return to Cousins Beach adds another layer of complexity as the three characters are forced to navigate their intertwined pasts under one roof.
Showrunner and author Jenny Han has indicated that while the final season stays true to the novel’s key themes, the television adaptation introduces notable changes, including an altered ending. These changes are designed to enhance emotional impact and make the series’ conclusion more resonant for viewers, some of whom may not be familiar with the original books. Han has also teased that the series will deliver emotional highs and lows, with some fans potentially heartbroken by the final outcome.
The reception to the premiere episodes has been largely positive, with fans flooding social media to voice their support for either “Team Conrad” or “Team Jeremiah.” Conrad, known for his introspective and emotionally guarded nature, continues to attract a loyal following of fans who believe his connection with Belly is both deep and enduring. Others appreciate Jeremiah’s openness and commitment, especially in light of his efforts to repair the relationship and propose marriage.
Beyond the romance, the series continues to explore themes of identity, grief, growing up, and finding one’s path in life. Belly’s opportunity to study abroad in Paris adds an additional layer of personal growth, as she must choose between stability with Jeremiah, lingering love for Conrad, and her own evolving dreams.
The show’s final season not only concludes Belly’s personal journey but also offers closure to several secondary storylines involving family, friendship, and the bittersweet nature of growing older. With the extended 11-episode run, viewers are given more time to experience the nuances of each character’s evolution, as well as the changing dynamic of Cousins Beach itself—a setting that has become a symbolic home for transformation and memory.
The Summer I Turned Pretty has been praised for its authentic portrayal of teenage emotions, picturesque summer visuals, and its ability to blend nostalgia with contemporary coming-of-age challenges. As Prime Video’s breakout young adult hit, the show has carved out a dedicated fanbase and helped revive interest in YA adaptations for television.
With nine episodes remaining, fans can expect more twists, heartfelt conversations, and potentially difficult decisions as the love triangle nears its conclusion. Whether Belly ends up with Jeremiah, returns to Conrad, or ultimately chooses herself, the final season promises to honor the spirit of growth, change, and youthful love that has defined the series.
