Supersuck - surf spot statistics

Supersuck in Indonesia is a world-class wave, and the swell and wind data reveal distinct seasonal patterns that influence surf quality. The swell is remarkably consistent year-round, with ground swell dominating (90% or higher in all months) and virtually no days without swell. The mean swell size ranges from 1.4m to 2.0m, peaking from June to September, offering the most powerful waves. However, wind conditions vary significantly, with April, October, and November standing out as the best months—combining strong ground swell (98-100%) with good wind conditions (71%, 73%, and 75% respectively). March, May, and September also provide decent wind percentages (44-59%), though with slightly smaller swells. The peak swell months (June-August) suffer from higher bad wind percentages (55-66%), making them less ideal despite the larger waves. December through February have the worst wind conditions (81-82% unfavorable), though the swell remains consistent. For advanced surfers prioritizing clean, barreling conditions, April and October-November are the prime windows, offering the best balance of swell consistency, size, and favorable winds. If you’re after raw power and can handle onshore winds, June-August delivers bigger waves but with compromised wind quality. Overall, Supersuck is a reliable wave, but timing your trip around wind conditions is critical for optimal performance.

April at Supersuck delivers consistent, high-quality surf with an average swell height of 1.5m and a solid 14.4s period, ensuring powerful, well-formed waves. The swell direction is predominantly SSW and SW, generating the majority of waves in the 1-2.5m range, with prime conditions between 1.5-2m (28.5% from SSW). The clean, long-period energy from these directions offers hollow, barreling waves ideal for advanced surfers. Winds are favorable 71% of the time, mostly light to moderate ESE to SE breezes (10-20kph), keeping conditions clean. However, stronger SE winds (20-30kph) do occur occasionally but rarely disrupt the lineup. Expect frequent overhead barrels with minimal wind interference—classic Indo perfection.
