Yallingup - surf spot statistics

Yallingup, Western Australia, offers consistent surf year-round, dominated by clean ground swells (89-95% prevalence) with minimal wind swell interference. The best months for quality surf are April through October, when swell energy peaks and wave heights average 1.5m to 2.3m—reaching their largest in June-August (2.2-2.3m). However, winter (June-August) brings challenging wind conditions, with only 21% favorable offshore winds. April and May stand out as the sweet spot: swell size builds (1.5m-1.8m) while wind conditions improve (31-34% good winds), offering cleaner faces. September-October retains solid swell (2.2m-1.7m) but winds deteriorate slightly. Summer (December-March) provides smaller, manageable waves (1.2m-1.3m), though onshore winds plague 71-78% of days. For advanced surfers, late autumn (April-May) delivers the optimal balance of size, consistency, and cleaner conditions, while winter suits those prioritizing raw power over wind quality.

In September, Yallingup offers solid surf conditions with an average swell height of 2.2m and a strong 13.8-second period, indicating powerful, well-spaced waves. The swell direction is predominantly from the WSW (49.03% of waves between 1-3m) and SW (6.42% in the same range), which aligns well with the break, creating consistent, high-quality rides. However, larger swells (over 2.5m) occur less frequently, ensuring manageable conditions for advanced surfers. Wind conditions are less favorable, with only 22% of the time being ideal (likely light offshore or cross-offshore). Winds often come from the W to SSW (10-30kph range, ~10-15% frequency), which can create choppiness, especially in the afternoons. Early mornings typically offer cleaner conditions. For experienced surfers, September delivers reliable, powerful waves, though wind management is key—dawn patrols are recommended. Smaller days (1-1.5m) are rare but provide more relaxed sessions. Overall, it’s a prime month for solid surf with occasional epic days.
