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 June, Yallingup offers consistent surf with an average swell height of 2.2m and a strong average period of 13.5s, indicating powerful, well-organized waves. The swell predominantly comes from the WSW (37% of waves between 1-2.5m) and SW (10.6% of waves in the same range), delivering clean, sizable surf with good energy. Smaller contributions from W and SSW directions provide variety, while northerly swells are negligible. Wind conditions are optimal for surfing only 21% of the time, with lighter winds (0-20kph) from the ENE, E, and SE (totaling ~6% of observations) offering the best conditions. However, stronger winds (20-50kph) from the N through W directions are common, potentially creating chop, especially during frontal systems. Expect a mix of clean mid-sized days and wind-affected sessions, with the best windows when offshore easterlies align with the dominant SW swell. The long-period WSW swells will produce the highest-quality waves, though larger sets (over 2.5m) occur 2.1% of the time, suited for advanced surfers.
