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.

October at Jan Juc offers solid surfing conditions with a consistent swell and a mix of wind patterns. The average swell height is 1.5m with a decent 13.0s period, providing good energy for rideable waves. The dominant swell direction is from the SW (26.6% in the 1-1.5m range and 20.7% in the 1.5-2m range), which aligns well with the beach's orientation, producing clean, workable waves. SSE and S swells also contribute, especially in the 1-2.5m range, adding variety to wave shapes. Wind conditions are less favorable, with only 24% of the time being ideal for surfing—typically when winds are light and offshore (NE to E directions). However, SW, WSW, and W winds (10-30kph) are more common, which can create choppy or cross-shore conditions. Overall, October delivers reliable waves, but wind quality is hit-or-miss, requiring surfers to time sessions for early mornings or days with lighter offshore breezes.
