Belly and Jeremiah Ages in Season 3
In season 3 of The Summer I Turned Pretty, Belly Conklin is 18 years old, while Jeremiah Fisher is also 18 at the start of the season, with both characters entering their final summer before college. The series, adapted from Jenny Han's bestselling novels, follows their evolving relationships during a pivotal year of change, and the age difference between the central love triangle remains a key focus for viewers tracking character timelines. For context on how the actors' real ages compare to the characters, see the cast details below.
The on-screen dynamic shifts as Belly and Jeremiah navigate post-high school plans, with the show explicitly referencing their upcoming college departures, reinforcing that they are both 18 during the events of season 3. This places the characters at the same age as the actors portraying them, which helps maintain a realistic tone for the coming-of-age drama. The series does not compress or expand their ages, keeping the timeline consistent with the source material.
Actor Birth Years and Real Ages
Fiona Palomo, who plays Belly, was born in 1996, making her 27 or 28 during filming, while Christopher Briney, who portrays Jeremiah, was born in 1998, placing him a few years younger in real life. Despite the age gap between the actors, both deliver performances that align with the 18-year-old versions of their characters, a casting choice that supports the show's focus on late-high-school summers. The casting process prioritized chemistry and acting range over exact age matching, a common practice in teen dramas.
The showrunners confirmed that the actors' ages were considered during casting to ensure they could credibly portray 18-year-olds navigating first love and family tensions. While Palomo and Briney are older than their characters, their life experience allows for nuanced performances that resonate with the target audience. This approach mirrors industry standards seen in other adaptations, where casting directors often select actors who can embody the emotional maturity of the roles.
Character Age Consistency Across the Series
Belly's age progression is clearly marked across the three seasons, starting at 15 in season 1, turning 16 in season 2, and reaching 18 in season 3, a trajectory that aligns with the book series' timeline. Jeremiah's age follows a similar path, with the character aging in lockstep with Belly to preserve the continuity of their shared history and the tension in their love triangle. This consistency helps fans track the characters' development without confusion.
The series uses dialogue and plot points, such as college application discussions and graduation scenes, to reinforce that both Belly and Jeremiah are 18 in season 3, avoiding any ambiguity about their stage of life. This attention to age detail supports the show's themes of transition and growing up, grounding the romance in a specific, relatable moment.
