There’s no strict age, but generally, a grom is anywhere from a little grommet just standing up to a teenager. Once they start driving themselves to the beach, getting their own boards, and maybe even getting a few sponsorships, they’re often called “young guns” or just young surfers. The grom phase is all about that wide-eyed, obsessive learning period where every session is an adventure and every wave, no matter how small, is totally epic.
