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.

August at Yallingup offers solid surf conditions with a consistent swell and varying wind patterns. The average swell height is 2.2m with a long period of 13.9s, providing powerful, well-formed waves. The most dominant swell direction is from the WSW, making up a significant portion of the waves, particularly in the 1-2.5m range, which is ideal for intermediate to advanced surfers. The wind is only favorable for surfing 21% of the time, with lighter winds (0-20kph) from the SE to SSW offering the cleanest conditions. However, stronger onshore winds from the SW, WSW, and W are common, which can create choppy or blown-out waves. Overall, August delivers quality surf with a mix of clean and rough days—best suited for those comfortable in bigger, more powerful surf.
