Prime Video officially premiered the third and final season of The Summer I Turned Pretty on July 16, 2025, concluding the popular coming-of-age series based on Jenny Han’s best-selling novels. The launch was part of a broader summer content rollout that included the action-comedy Heads of State, which debuted on July 2, and Ballard, a new spinoff of the Bosch franchise, which premiered on July 9. These releases reflect Prime Video’s continued strategy to dominate summer streaming with a mix of youthful drama, high-stakes action, and fan-favorite franchises.
The final season of The Summer I Turned Pretty consists of 11 episodes. It kicked off with a two-episode premiere, with subsequent episodes releasing weekly on Wednesdays. The finale is slated for September 17, giving fans a steady flow of summer entertainment. The series, anchored in emotional storytelling and romantic tension, has maintained strong viewership since its first season premiered in June 2022. According to Amazon, viewership doubled with Season 2, securing the show’s place as one of Prime Video’s top Gen Z-targeted titles.
This season continues to explore the evolving dynamics between Belly (Lola Tung), Jeremiah (Gavin Casalegno), and Conrad (Christopher Briney), as they transition from teenagers at Cousins Beach to young adults facing more complex emotional and personal challenges. The premiere revealed a new rift in Belly and Jeremiah’s relationship after it’s disclosed that Jeremiah was romantically involved with someone else during their break. This tension reopens questions about loyalty and trust, key themes that resonate with viewers navigating similar issues in real life.
The story also introduces new complications for the supporting cast. Belly’s brother, Steven (Sean Kaufman), becomes the center of a dramatic subplot after a serious car accident leaves him in a coma. The incident raises the emotional stakes for the entire group of friends and family, adding a layer of gravity to a show often known for its idyllic settings and summer romances.
Jenny Han, the author and executive producer, recently commented on the season’s narrative direction in an interview with People, saying that it’s “debatable” whether Jeremiah’s actions constitute cheating. She emphasized that relationship boundaries are often unclear, especially among young people, and the show doesn’t offer easy answers. That emotional ambiguity, she added, is part of what makes the series so relatable to its core audience.
The series has also evolved visually and thematically with each season. Where the first season centered on teenage crushes and beach bonfires, Season 3 shifts toward the realities of college life, long-distance relationships, and growing independence. Critics have noted that the final season feels more mature and grounded, a natural progression for characters who are no longer high schoolers but young adults making life-altering decisions.
With the premiere dropping at midnight Pacific Time, The Summer I Turned Pretty continues the trend of “event viewing,” where fans stay up late or wake early to watch new episodes immediately upon release. This model has proven effective for streaming platforms trying to build week-to-week momentum and keep social media engagement high. For Amazon, maintaining consistent buzz around its tentpole series is crucial in a competitive summer landscape that includes new releases across Disney+, Netflix, and Hulu.
The show’s ability to maintain cultural relevance while adhering closely to its source material has been praised by longtime fans of the books. Unlike some adaptations that stray far from their origins, The Summer I Turned Pretty has stayed mostly faithful to Han’s original trilogy, offering a narrative that feels complete and purposeful. That consistency, combined with strong performances and a clear understanding of its target demographic, has helped the series achieve both critical and commercial success.
This final season not only closes the chapter on a beloved romantic saga but also marks an end to an era for Prime Video’s youth-oriented programming. As streaming services increasingly prioritize franchise building and global audiences, The Summer I Turned Pretty stands out as a rare example of a show that grew with its characters and viewers, offering a satisfying arc from beginning to end.
Fans can expect an emotionally charged farewell as the remaining episodes roll out weekly. With its mix of nostalgia, heartbreak, and personal growth, The Summer I Turned Pretty bids adieu not just to Cousins Beach, but to a transformative period in its characters’ lives—one that mirrors the bittersweet passage from adolescence to adulthood.
