The emotional weight of the final season rests squarely on the shoulders of the talented core cast, who have embodied the complex characters created by Jenny Han. Their return is confirmed for the final installment, which was filmed primarily in North Carolina, the "Tar Heel state."
- Isabel "Belly" Conklin (Lola Tung): The protagonist whose coming-of-age story is at the heart of the series. Season 3 sees her navigating college and the final, life-altering decision about her future and her heart.
- Conrad Fisher (Christopher Briney): The brooding, intellectual older brother, representing Belly's first love and deep, enduring connection. His journey in the final season is one of maturity and acceptance.
- Jeremiah Fisher (Gavin Casalegno): The charming, golden-retriever younger brother, who offers Belly stability and undeniable chemistry. He is Belly’s current romantic partner as the season begins.
- Steven Conklin (Sean Kaufman): Belly's older brother, dealing with his own romantic entanglement with Taylor and recovering from a car accident.
- Taylor (Rain Spencer): Belly's best friend, whose relationship with Steven is a key subplot.
- Laurel Park (Jackie Chung) & Susannah Fisher (Rachel Blanchard): The mothers whose lifelong friendship and shared history form the foundation of the Cousins Beach summers.
The Final Countdown: Season 3 Release Date, Episode Schedule, and The End
The anticipation for The Summer I Turned Pretty Season 3 has reached a fever pitch, and the most current information provides a clear schedule for the show’s conclusion. This will be the final installment of the Prime Video series, adapted from the third and final book in Jenny Han's trilogy.
Confirmed Premiere Date: Wednesday, July 16, 2025
The third and final season of The Summer I Turned Pretty is officially set to premiere on Wednesday, July 16, 2025. This is a crucial piece of information for all fans eager to return to the drama of Cousins Beach. The final chapter will kick off with a multi-episode premiere, allowing viewers to dive immediately back into Belly's world.
Weekly Release and Episode Count
Following the premiere, new episodes will be released every Wednesday. This weekly release model is designed to sustain the conversation and the passionate "Team Conrad" vs. "Team Jeremiah" discourse throughout the summer. While the exact total episode count is not widely confirmed, fans can expect a substantial final season that fully adapts the final novel, We'll Always Have Summer.
Plot Secrets: What We Know About Belly's Final Choice and the Wedding Teaser
Season 3 picks up after a tumultuous sophomore year of high school and Belly’s junior year of college, with her relationship with Jeremiah still intact. The show, led by creator Jenny Han, has a roadmap to follow: the plot of the third book, We'll Always Have Summer. However, the series has already introduced changes, meaning fans of the book should prepare for some significant deviations, even as the ultimate ending remains fixed.
The Book's Ending: An Inevitable Choice
The third book sees Belly and Jeremiah’s relationship facing severe challenges, eventually leading to a dramatic moment where they decide to get married young. This impulsive decision creates tension with Conrad and their families. The story ultimately concludes with Belly making a definitive choice between the two brothers, a choice that has been the subject of countless fan debates for years. The show is confirmed to be the "final season," suggesting a clear resolution to the love triangle.
The Shocking Wedding Teaser
A major spoiler, or at least a highly significant tease, came with the release of the official trailer in June 2025, which prominently featured Belly getting married. This visual confirmation immediately sent shockwaves through the fandom. While this aligns with a major plot point in the third book, the trailer leaves the most important question unanswered: Is Belly walking down the aisle to marry Conrad or Jeremiah? This is the central mystery that the final season will unravel.
The Stakes Are Higher Than Ever
The final season is not just about romance; it's about growing up. Belly's journey is a coming-of-age story centered on finding herself and determining what true, lasting love looks like. The themes of family, loss (following Susannah’s passing in Season 2), and the transition to adulthood will be heavily explored. The cast, including Lola Tung, Christopher Briney, and Gavin Casalegno, have discussed the emotional weight of filming the final chapter, suggesting a powerful and tear-jerking conclusion.
Topical Authority: The Enduring Power of Team Conrad vs. Team Jeremiah
The success of The Summer I Turned Pretty is inextricably linked to the fervor of the love triangle. The show has masterfully balanced the two sides, making both Conrad and Jeremiah compelling options for Belly. This passionate discourse is a core entity of the show's topical authority.
- Team Conrad: Represents a deep, soulful connection, a love that is often painful and complicated, rooted in shared history and a "we'll always have summer" kind of destiny. Conrad is the 'endgame' choice for many book purists.
- Team Jeremiah: Represents fun, stability, and a love that is easy and supportive. Jeremiah offers Belly a present-day happiness and a relationship that is less fraught with emotional baggage.
Showrunner Jenny Han has consistently emphasized the importance of the books' core story while allowing the TV adaptation to breathe new life into the characters. She serves as both the creator and executive producer, ensuring that the spirit of her original work is maintained, even as modern elements and new subplots (like Steven and Taylor’s relationship) are introduced. Ultimately, the final season is a celebration of the Cousins Beach atmosphere—a setting that feels like a character itself—and the enduring power of first love, friendship, and family bonds.
