When The Summer I Turned Pretty first premiered on Prime Video in June 2022, the teen drama based on Jenny Han's novel of the same name was a bubbly summer dream and the perfect escape for fans of complicated love triangles and vicarious heart-fluttering feelings. Season 2 of the teen series, based on the sequel novel It's Not Summer Without You, was much heavier. The second installment balanced a present-day crisis—in which Belly (Lola Tung), Conrad (Christopher Briney), and Jeremiah (Gavin Casalegno) have to reunite to keep their aunt (Kyra Sedgwick) from selling off the beloved Cousins beach house—with flashbacks to a year of loss and heartbreak, as Belly and the boys work through their grief from the loss of Fisher matriarch Susannah (Rachel Blanchard).

Several of the scenes were as emotional and moody as Conrad's day-to-day personality, then the lightest moments occurred once Belly and the Fisher brothers got over their love triangle long enough to be genuine friends. That's not to mention Steven (Sean Kaufman) and Taylor's (Rain Spencer) budding relationship and the welcome addition of the boys' cool cousin Skye (Elsie Fisher).

Season 2's eight episodes concluded on August 18, 2023, with the Conklins and Fishers saving the summer house and Belly finally making a choice, choosing a future with Jeremiah over rekindling her relationship with Conrad. However, fans of the books knew that this story wasn't over yet, and Prime Video renewed the show for a third season while season 2 was still airing. With new episodes finally arriving this summer, we're looking at the future of The Summer I Turned Pretty and everything we know about season 3.

When will 'The Summer I Turned Pretty' season 3 come out?

Prime Video has announced that The Summer I Turned Pretty will return for season 3 in July 2025, two years after season 2's airing. The current hiatus between seasons has been double the length of the show's one-year break between seasons 1 and 2. To make up for it, the upcoming installment has been expanded to 11 episodes, making it the longest The Summer I Turned Pretty season yet.

Cameras began rolling on season 3 in May 2024. At the time, Prime Video announced the news via a video of The Summer I Turned Pretty cast back on set, playing beach volleyball.

Is season 3 the last season of 'The Summer I Turned Pretty?'

All good things must end, including our favorite teen TV shows. Ahead of the new season, Prime Video revealed that The Summer I Turned Pretty season 3 will be the show's final installment. The streamer also released the first poster for the new season on March 7, 2025.

The decision to end TSITP at season 3 means that the show will be the same length as the three-book series, with each season adapting one of the novels.

Who will be in the cast of 'The Summer I Turned Pretty' season 3?

Season 2 saw the show stick to its main cast of Conklins, Fishers, and friends, with unfortunately fewer appearances from the deb squad. If the show sticks with that trend, the most likely stars we'll see in season 3 include Lola Tung (Belly), Christopher Briney (Conrad), Gavin Casalegno (Jeremiah), Sean Kaufman (Steven), Jackie Chung (Laurel), Rain Spencer (Taylor), and David Iacono (Cam). Hopefully, season 2 additions Elsie Fisher (Skye) and Kyra Sedgwick (Julia) will also stick around, and Rachel Blanchard (Susannah) will likely be back for some tear-jerking flashbacks.

What will happen on 'The Summer I Turned Pretty' season 3?

The third book of Jenny Han's trilogy, We'll Always Have Summer, revisits Belly and the boys two years after the events of season 2. Belly and Jeremiah have been dating for two years while attending the same college, and they eventually decide to make their relationship forever. Meanwhile, Conrad has spent the past two years still loving Belly but feels like he lost his chance. However, as he and Belly spend lots of time together over the summer, they must face feelings that may have never gone away. So when season 3 arrives, expect a time jump, wedding planning, and renewed love triangle angst.

So far, Han has been tight-lipped on whether the new season will include any major changes from the books, recent additions to the cast like Aunt Julia and Skye, or Steven and Taylor's romance. In an August 2023 interview with Deadline, she told the outlet, "I am looking forward to giving the fans the iconic moments of the third book that they’re expecting, but also looking forward to being able to hopefully surprise and delight them as well."
