Spain clinched the copper medal with a tally of 5,252.
Dimitri Poulos, a last-minute call-up to the American team, sealed the boys' under-18 title for the US with a wave score of 15.33 points in the final.
Mexico's Alan Cleland claimed silver, Poulos' compatriot Tommy Coleman finished third and Joh Azuchi of Japan did enough for the copper medal.

Minami Nonaka of Japan received silver, while Noah Lia Kapp of Germany and Sara Wakita of Japan ended with bronze and copper respectively.
The girls' under-16 crown was secured by Kapp, who scored 11.34 points in the final before competing in the under-18 division minutes later.
Zoe Benedetto of the US earned silver, Hawaii's Betty Lou Sakura Johnson did enough for bronze and American Caitlin Simmers claimed copper.
"The future generation of surfers have once again risen to the occasion and performed on the greatest stage for under-18 surfers," said International Surfing Association President Fernando Aguerre.
"These young world champions are following the footsteps of many legends before them, paving their own pathway towards stardom, and for some towards the Olympic Games.
"Some of the surfers that competed this week have already placed a foot into the Tokyo 2020 Games with provisional qualification, showcasing the youthful demographic of our sport.
"If surfing is to be included in future editions of the Games, it is these surfers that we see today with medals that will likely be representing their nations in 2024, 2028, and beyond."
