  description: Cloudbreak is a world-renowned left-hander that breaks over a pristine coral reef in the open ocean off Fiji's Tavarua Island. The wave can handle virtually any size—from fun 4-footers to triple-overhead bombs—and delivers long, makeable barrels across multiple sections. When large S-SW swells arrive during the May-October season, Cloudbreak transforms into one of the world's most powerful waves. Access is by boat only, keeping crowds manageable despite its fame. The warm, crystal-clear water and consistent trade winds make this a bucket-list destination.
