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.

November at Jan Juc offers consistent surf with an average swell height of 1.4m and a solid period of 12.3s, ensuring well-formed waves. The dominant swell direction is from the SW (29.5% of waves in the 1-1.5m range), contributing to quality groundswells, while smaller but still surfable ESE-SSE swells appear occasionally. Wind conditions are less favorable, with only 20% of days providing ideal offshore or light cross-shore winds (typically from the N-NW). Stronger onshore winds (SSE-SW) prevail, especially in the 10-30kph range, which can disrupt wave quality. The best sessions occur when SW swells coincide with lighter NW winds, offering cleaner faces. Expect a mix of waist-high to overhead waves, with larger sets (1.5-2.5m) appearing regularly. While not epic, November is surfable, requiring patience for wind windows.
