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.

July at Jan Juc offers consistent surf with an average swell height of 1.5m and a solid period of 13.4s, producing clean, powerful waves. The dominant swell direction is SW, accounting for 26.37% of waves in the 1-1.5m range and 20.29% in the 1.5-2m range, ensuring quality groundswells. Larger swells (2m+) are less frequent but still present, primarily from the SW and SE directions. Wind conditions are favorable for surfing only 30% of the time, with lighter winds (0-20kph) mostly from the N/NW quadrants. However, stronger onshore winds (20-40kph) from the W/SW can deteriorate conditions. The mix of SW swells and occasional SE energy provides varied setups, but optimal sessions rely on lighter winds aligning with the swell. Overall, July delivers reliable waves for experienced surfers, though patience is needed for the best wind-window opportunities.
