Jeremiah Fisher is a teenager in The Summer I Turned Pretty , generally portrayed as around 16–17 years old in the main events of the story.

Quick Scoop: Jeremiah’s Age

  • In the first summer of the story (when Belly turns 16), Jeremiah is the same school-year age as Belly’s brother Steven and about a year younger than Conrad, putting him in the 16–17 range.
  • Across most of the books and early TV seasons, fans and breakdown articles place Jeremiah at roughly 16 in Season 1 and around 17–18 by Season 2 , as time passes in the story.
  • Some detailed character guides summarize him as about 17–18 years old depending on where you are in the timeline of the trilogy , since each book pushes the characters slightly older.

Why the age can seem confusing

Different fan sites and explainers sometimes say “16–17” or “17–18” because:

  • The books span multiple summers, so Jeremiah ages with each installment.
  • The show closely follows that coming-of-age timing but doesn’t constantly state exact birthdays on screen.

So if you’re just asking “how old is Jeremiah in The Summer I Turned Pretty?”, the safest, fandom‑accepted answer is: he’s a mid‑teen, about 16–17 years old in the main story , growing toward 18 as the series moves into later seasons and books.
