Jan Juc - surf spot statistics

Jan Juc in Australia offers consistent surf conditions year-round, with ground swells dominating across all months, peaking from April to September at 90% or higher. The best months for surfers are typically from April to September, when ground swell reliability is highest (90–94%) and mean swell size ranges from 1.5m to 1.6m. During this period, wind conditions are relatively better compared to summer months, with good wind days occurring 28–32% of the time—still not ideal, but significantly improved over summer’s 15–20%. The winter months (June–August) provide the most consistent swell size and quality, though offshore winds remain somewhat inconsistent. Conversely, summer (December–February) sees slightly smaller swells (1.4m) and far worse wind conditions, with bad winds occurring over 80% of the time, making sessions heavily dependent on timing. Autumn (March–May) and spring (September–November) serve as transitional periods, with March and April showing early improvements in swell consistency while October and November begin to see a decline. For surfers prioritizing quality over frequency, late autumn to early spring (May–September) delivers the most dependable combination of swell size and cleaner conditions despite the persistent challenge of onshore winds.

April at Jan Juc offers moderately consistent surf conditions, with an average swell height of 1.5m and a solid period of 13.1s, ensuring well-organized waves. The dominant swell direction is from the SW, contributing the highest frequency of rideable waves (28.96% in the 1-1.5m range and 19.98% in the 1.5-2m range), followed by SSW and SSE, which add variety to the lineup. Smaller swells from the SE and S bring additional opportunities, though with slightly less power. Wind conditions are favorable 28% of the time, with lighter offshore or side-offshore winds (NNE to ESE) providing clean faces, particularly in the mornings. However, stronger onshore winds (SW to W) can occasionally disrupt conditions, especially in the afternoons. Overall, April delivers a mix of mid-sized swells with decent shape, best suited for intermediate to advanced surfers who can capitalize on the SW energy and time their sessions around wind shifts.
