‘The Summer I Turned Pretty’ Season 3 Premieres July 16 on Prime Video: Final Chapter Details Revealed

It’s almost time to head back to Cousins Beach — one more summer, one final decision. The Summer I Turned Pretty returns with Season 3 on July 16, and fans are already bracing for the emotional rollercoaster that’s sure to hit. Based on Jenny Han’s best-selling book trilogy, the series has followed Belly’s complicated, heart-tugging love story since Season 1. And now, it all leads to this.

Season 3 will officially be the last, and there’s a lot at stake. If you’ve been watching since the beginning, you already know: this isn’t just about a summer crush anymore. Belly’s all grown up, and the choice she’s about to make will change everything.

Where things left off

Season 2 ended with Belly deciding to move forward — or at least trying to. After an emotional whirlwind with Conrad, she chose to focus on her future and give her relationship with Jeremiah a real shot. It was a big step. But this is Cousins, and in Cousins, nothing stays in the past for long.

That means yes, Conrad’s still in the picture. According to the official logline, Belly’s ready for another summer with Jeremiah, but some “core-shaking events” bring Conrad back into her orbit. Cue the drama, the angst, and the impossible choices.

Jenny Han promises surprises

If you think you know exactly what’s going to happen just because you read the books, think again. Jenny Han, the author and showrunner, told Entertainment Weekly that there are definitely going to be twists. “There are the things they know and then there are things they think they know,” she teased. So even book readers might want to buckle up.

The main focus and who else is returning

Season 3 is all about Belly’s final choice — Jeremiah or Conrad. But that doesn’t mean we won’t get to see what’s happening with everyone else. Steven, Belly’s brother, and Taylor, her best friend, are both back. They’ve had storylines bubbling under the surface, and it sounds like they’ll get more screen time this season.

Here’s the main cast lineup for Season 3:

• Lola Tung as Belly
• Christopher Briney as Conrad Fisher
• Gavin Casalegno as Jeremiah Fisher
• Sean Kaufman as Steven
• Rain Spencer as Taylor
• Jackie Chung as Laurel, Belly’s mom

Also expect to see familiar faces like Susannah (Rachel Blanchard), Cam (David Iacono), Skye (Elsie Fisher), and Aunt Julia (Kyra Sedgwick). Some new cast members are also joining the final season, including Isabella Briggs and Kristen Connolly as series regulars, along with Sofia Bryant, Lily Donoghue, Zoé de Grand’Maison, Emma Ishta, and Tanner Zagarino in recurring roles. No word yet on who they’ll play, but it’s safe to assume they’ll stir things up a bit.

Where the story picks up

Belly is now in college, looking ahead at adulthood, but summer in Cousins has a way of pulling everyone back. It’s the summer after her junior year, and while she’s planning to spend it with Jeremiah, the past refuses to stay behind. The story follows her as she faces one final emotional test — deciding who she wants to build a future with. Her heart may be with Jeremiah now, but fans know how strong the connection with Conrad has always been.

It’s not going to be simple. It never is. And according to the official teaser, “summer will never be the same.”

The third and final season of The Summer I Turned Pretty premieres July 16 exclusively on Prime Video. If you’re not caught up yet, now’s the time. Seasons 1 and 2 are available to stream, so you can binge your way through all the drama, kisses, tears, and beach sunsets before the final chapter begins.
