Uluwatu - surf spot statistics

Uluwatu, Bali, is a world-class reef break with consistent year-round swell, predominantly powered by ground swells (90%+ of the time). The best months for surfing here combine solid swell size with favorable wind conditions. From April to October, the swell is most reliable, peaking in June, July, and August with mean swell heights of 2.0–2.2m, ideal for advanced surfers. However, wind conditions vary significantly—April, September, October, and November offer the best balance, with good offshore winds occurring 51–76% of the time. October stands out as the prime month, with 74% good wind conditions and a solid 1.8m average swell. The dry season (May–September) brings bigger waves but often suffers from less ideal winds (only 21–31% favorable in peak swell months). Conversely, November and March provide decent swells (1.5m) and better wind setups, making them good alternatives. December to February sees slightly smaller swells (1.5–1.6m) and the worst wind conditions (78–79% onshore), though ground swells remain dominant. For the best all-around experience, target April, September, October, or November—when swell consistency, size, and wind align most favorably.

In February, Uluwatu sees a consistent swell with an average height of 1.6m and a solid period of 13.1s, indicating well-organized, powerful waves ideal for intermediate to advanced surfers. The predominant swell direction is from the SSW and SW, with the majority of waves ranging between 1-2.5m—offering a good mix of intermediate and larger, more powerful sets. Wind conditions are favorable 21% of the time, typically light and variable early in the day, though WSW and W winds can pick up to 10-30kph in the afternoons, potentially causing some chop. For the best sessions, aim for mornings when winds are lighter and swells are clean. The spot handles larger waves well, but the stronger afternoon winds may require timing your sessions strategically. Overall, February delivers reliable, quality surf for those comfortable with overhead conditions.
