  description: Namotu Lefts is one of Fiji's most consistent high-performance waves—a hollow left-hander that breaks right in front of the Namotu Island Resort. The wave produces powerful, roping barrels that can handle swell up to 15 feet, offering world-class tubes on a more predictable platform than Cloudbreak. The reef is user-friendly, the channel is deep, and the position allows for early morning perfection before the trades kick in. If you're staying at Namotu, this is your backyard—and what a backyard it is.
