10| Nathan Florence
Birthday: June 10, 1994
Hometown: Pupukea, Hawaii

Sibling rivalry breeds better surfers—just look at Bruce and Andy, C.J. and Damien, or Cory and Shea. And though Nathan and John John may actually be part of a tight-family unit, in his own, quiet way, Nathan is undeniably motivated by his older brother’s surf-celebrity status. Like he did for John John, Pete Johnson’s been helping Nathan, which may be paying off more on land than in the water, as he’s developed a taste for reading and does well in school. Also like John John, Nathan doesn’t scare easy. His Pipeline act is quickly catching up with big brother’s, and as he develops and comes into his own, much like Bruce did with Andy, Nathan will craft his own identity and persona.

11| Matthew Costa
Birthday: July 27, 1993
Hometown: Waianae, Hawaii

Waianae is not an easy place to grow up—adversity, challenges, and distractions lurk in every beachpark—but for an aspiring young surfer dead set on taking the right path, it’s also one of the best places. Growing up under the watchful eyes of the Keaulana clan, with the spirit of Rell Sunn in the air and spots like Makaha and Third Dip serving as idyllic training grounds, Matty Costa’s competitive savvy is quickly garnering him respect throughout the islands, as well as across the pond on the mainland. Consistently taking out mini-grom heroes like Koa Smith and LahiKoila Minamishin, a breakthrough win is only a matter of time. Following in the footsteps of west-siders like Sunny Garcia and Johnny Boy Gomes, Costa’s already demonstrating a penchant for power. The able goofyfooter’s top turn is as solid as they come for his age, and thanks to the progressive nature of his generation, the technical maneuvers and tricks are rapidly evolving as well.
