The Summer I Turned Pretty Season 3 Trailer: Everything You Missed In The Final Cousins Beach Preview
The highly anticipated trailer for The Summer I Turned Pretty Season 3 has officially dropped, confirming the final chapter of Belly, Conrad, and Jeremiah’s iconic love triangle will be an emotional roller coaster. As of this current date in late 2025, the buzz is deafening, with fans dissecting every single frame of the preview for clues about who Belly Conklin finally chooses. Amazon Prime Video has set the stage for one last unforgettable summer at Cousins Beach, and the trailer gives us a tantalizing glimpse into the high-stakes drama and pivotal life decisions that await our favorite characters.
The third and final season, based on Jenny Han’s third novel, We'll Always Have Summer, has been the subject of intense speculation for over a year. The trailer’s release on Wednesday, June 11, 2025, was a major event, not only providing a clear look at the season's tone but also solidifying the July 16, 2025, premiere date. This season is poised to be the most dramatic yet, forcing Belly to confront her feelings for both Fisher brothers and ultimately decide her future.
The Final Summer: Season 3 Premiere and Trailer Breakdown
The countdown is officially on for the final season of The Summer I Turned Pretty. The journey back to Cousins Beach begins on Wednesday, July 16, 2025, exclusively on Prime Video. Unlike the first season’s binge-release model, Season 3 will follow the weekly format established by Season 2, with new episodes dropping every Wednesday. The series and season finale is scheduled for September 3, 2025, ensuring the summer-long emotional saga concludes just as the real summer ends.
The June 11th trailer release was the definitive signal that the end is near. It perfectly captured the bittersweet tone of the third book, blending the carefree joy of a final summer with the heavy weight of impending adulthood and life-altering choices. Key moments from the trailer that have fans buzzing include:
- The Engagement Ring Reveal: The trailer subtly hints at the major plot point from the book, where Belly and Jeremiah take a significant, and perhaps premature, step in their relationship. The pressure of this commitment is palpable in the preview.
- Conrad's Return: Christopher Briney's character, Conrad Fisher, is shown grappling with his feelings and the reality of Belly moving on with his brother. His emotional turmoil is a central focus, promising intense confrontation and heartfelt scenes.
- Cousins Beach Nostalgia: We see familiar, sun-drenched settings, from the boardwalk to the beach house, all tinged with a sense of finality. The location itself feels like a character whose story is also concluding.
- The College Dynamic: The season will explore the transition to college life, adding new pressures to the already strained relationships. The trailer shows a glimpse of Belly's life away from the beach, suggesting the drama won't be confined to the summer months.
Showrunner Jenny Han has promised a faithful, yet updated, adaptation of the source material. The trailer confirms that while the core elements of the book are present, the series will continue to explore the characters' growth in a way that resonates with a modern audience.
What We Know About the Season 3 Plot (Based on the Book)
Season 3 is based on We'll Always Have Summer, the final novel in Jenny Han’s trilogy. The official synopsis hints at Belly (Lola Tung) spending another summer in Cousins with her "soulmate, Jeremiah" (Gavin Casalegno), feeling like her future is set. However, the return of Conrad (Christopher Briney) and the unresolved feelings between them threaten to derail everything.
The core conflict of the season is Belly's ultimate decision between the two brothers. The previous season ended with Belly choosing Jeremiah, but the trailer makes it clear that the love triangle is far from over. This season will explore themes of commitment, self-discovery, and the true meaning of a soulmate.
Here are the major plot points and entities expected to drive the narrative:
- The Belly-Jeremiah Relationship: The season will explore the intensity and challenges of their relationship, including a major, life-altering decision that forces them to grow up quickly.
- Conrad's Perspective: Having lost Belly to his brother, Conrad must navigate his grief, his academic future, and his lingering feelings for Belly. His journey of self-acceptance and moving on (or trying to) is critical.
- The Fisher Family Legacy: The shadow of Susannah’s death still looms, and the brothers must learn to coexist while dealing with their mother’s absence and the future of the beach house.
- Taylor and Steven: The developing relationship between Taylor (Rain Spencer) and Steven (Sean Kaufman) is expected to provide a lighter, yet still compelling, secondary romance, offering a contrast to the intensity of the main love triangle.
- Laurel’s Role: Belly’s mother, Laurel (Jackie Chung), will continue to offer guidance, often through her own complicated experiences with love and loss.
The Returning Cast and Key Entities
One of the most reassuring takeaways from the trailer and official announcements is the return of the entire main ensemble. The chemistry between the core cast is the heart of the show, and their return ensures the final season maintains its emotional integrity. Filming for the season took place in North Carolina over the summer of 2024, maintaining the authentic coastal atmosphere of Cousins Beach.
