The Summer I Turned Pretty Season 3 has 11 episodes.
The third season is also the final season of the Amazon Prime Video series. Its episode count is higher than Season 1’s seven episodes and Season 2’s eight episodes, giving the concluding story a longer run.
Season 3 premiered on July 16, 2025, with its first two episodes released together. The remaining episodes followed weekly, creating an 11-week conclusion to Belly Conklin’s story and her complicated relationships with Conrad and Jeremiah Fisher.
The series is based on Jenny Han’s trilogy of novels: The Summer I Turned Pretty, It’s Not Summer Without You, and We’ll Always Have Summer. Because the television adaptation’s third season is its final one, viewers sometimes confuse the 11-episode order with the three-book source material or with the episode counts of the earlier seasons.
