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.

April at Uluwatu delivers consistent, quality surf with a dominant SSW swell direction, making it a prime time for experienced surfers. The average swell height is 1.6m, paired with a solid 14.4s period, ensuring powerful, well-formed waves. Most of the swell falls in the 1-2.5m range, with the highest frequency between 1.5-2m (35.72% SSW). This means plenty of overhead, barreling waves, particularly on the mid to high tide. Winds are favorable 60% of the time, predominantly light to moderate ESE to SE breezes (10-20kph), keeping conditions clean. Stronger winds are rare, but occasional ESE gusts (20-30kph) can briefly affect the lineup. Expect a mix of long, walled-up sections and fast, hollow takeoffs, especially when the SSW swell peaks—best suited for confident surfers comfortable with reef breaks. Overall, April offers high-performance waves with reliable offshore winds.
