10-day surf forecast with Strike Scores for St Leu, Réunion Island, Réunion
St Leu is one of the world's best left-hand barrels—a fast, hollow reef break on Réunion Island that produces some of the most intense tubes in the Indian Ocean. The wave is world-class, but the risk is extreme: Réunion has the highest shark attack rate on Earth, and surfing has been heavily restricted. When conditions align, St Leu delivers jaw-dropping perfection, but the shadow of danger looms over every session. Surfing's ultimate risk-reward equation.
