There are no more episodes of "The Summer I Turned Pretty" beyond the 11 episodes of Season 3. Season 3 is the final season, based on the third and last book in Jenny Han's trilogy, and it officially consists of 11 episodes with no confirmed bonus or additional episodes planned. The season 3 finale (episode 11) aired on September 17, 2025, concluding the series. While fans have speculated about a possible bonus 12th episode due to certain details and episode labeling, the official word from Amazon Prime Video and the show's creator is that the story ends with episode 11. Any extra content after the finale would likely be in the form of bonus material such as behind-the-scenes footage, deleted scenes, or cast interviews rather than a full episode. Season 4 is not planned for the series.
