Let’s be honest: the first time you watch The Summer I Turned Pretty, you spend half the show doing mental math. You’re not alone. We’ve all been there, squinting at the screen like it’s a tax form, trying to figure out if Belly is a high schooler or a college freshman who forgot to do her laundry.
The age situation in Cousins Beach is less of a timeline and more of a vibe. It’s like when you show up to a family barbecue and your cousin’s new girlfriend is definitely 25 but everyone just calls her “one of the kids.” The show thrives on that beautiful, sun-soaked confusion.
The Core Crew: Belly, Conrad, and Jeremiah
Let’s start with our leading lady, Isabel “Belly” Conklin. In the books, she’s a fresh-faced 15 in the first summer, turning 16 in the second. In the show, they aged her up a bit so the kissing scenes wouldn’t feel like a federal crime, landing her around 16-17 for the bulk of the drama. That’s the sweet spot where you’re old enough to drive but still young enough to think a moody boy’s silent treatment is a personality trait.
Then we have the Fisher brothers, the human equivalents of a storm cloud and a golden retriever. Conrad, the brooding eldest, is supposed to be 18-19. He’s that guy who smokes on the porch and acts like he pays taxes, but really, he’s just stressed about AP Chemistry. Jeremiah, the fun one, is a year younger, hovering around 17-18. He’s the human embodiment of a warm beer—harmless, refreshing, but you know it’s not the classy option.
Honestly, their ages only matter because it explains their behavior. Conrad acts like he’s 40 and tired of life. Jeremiah acts like he’s 14 and just discovered fire. It’s the classic yin and yang of teenage angst.
The Perpetual Adults: The Moms and Dads
Now, here’s where the math gets fuzzy. Laurel and Susannah are technically in their late 40s, but they dress like cool indie rock stars from the 90s. They’re the moms who let you have a sip of wine and then gossip about the neighbors like they’re still in high school. They’re not just parents; they’re the blueprint for “aging gracefully with a side of chaos.”
The dads are a different story. Cleveland is probably in his early 50s, but he exists purely to offer philosophical advice and grill burgers. He’s like a wise old owl who just happens to have a dad bod. The whole adult crew is stuck in a time warp where summer never ends and mortgages don’t exist.
Why It Feels So Confusing (And Why That’s Okay)
The show plays fast and loose with ages because it wants you to feel the nostalgia, not the paperwork. Think about your own life: when you’re 16, a 19-year-old seems ancient and wise. By the time you’re 25, you realize 19-year-olds are basically toddlers with driver’s licenses. The show leans into that illusion.
TSITP Season II Review – JTC Journal
You’ll catch yourself thinking, “Wait, is she in middle school?” only to see her sipping a soda at a beach party with senior citizens. It’s like when you run into your neighbor’s kid and realize they have a beard now. Time is a flat circle, and so is the age chart in this universe.
Also, the actors are clearly not their ages. Gavin Casalegno (Jeremiah) is in his mid-20s, and Christopher Briney (Conrad) is too. But that’s Hollywood, baby. They cast 25-year-olds to play teenagers so we can all feel slightly inadequate about our skin care routines.
The Real Answer: Doesn’t Matter, Have Fun
If you try to pin down exact birthdays, you’ll spiral. It’s like asking how many licks it takes to get to the Tootsie Roll center of a Tootsie Pop—the world may never know. The point is that Belly is young enough to be reckless and old enough to drive the plot forward.
So, the next time you’re watching and someone says, “But she’s a junior!” just shrug and say, “She’s a summer junior.” It’s a special designation that means “emotionally 30, legally 16, and ready to cry on a beach.” We’ve all been there, just with worse lighting.
In conclusion, the ages in Tsitp are a suggestion, not a rule. They’re like the “serving size” on a bag of chips—technically accurate, but nobody pays attention. Just enjoy the chaos, the love triangles, and the fact that everyone is somehow simultaneously too young and too old for their own good.
And remember: if you feel old watching them, just wait ten minutes. The show will have a time jump, and you’ll feel ancient all over again.
