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.

June at Uluwatu offers powerful, consistent surf with an average swell height of 2.0m and a solid 15.0s period, producing well-spaced, clean lines. The dominant swell direction is from the SSW-SW sector, with 55% of waves in the 1.5-2.5m range, ideal for advanced surfers. However, wind conditions are tricky, with only 31% of days providing ideal offshore (E-ESE) winds. The majority of winds are ESE-SE, often blowing 10-30kph, which can create cross-shore or onshore choppiness, particularly in the afternoons. Smaller days (1-1.5m) are rare but manageable for intermediates, while larger swells (18% of days 2.5m+) deliver heavy, barreling waves. Expect crowded lineups when winds align. Overall, June delivers high-quality surf but requires patience for optimal wind windows.
