Avalon - surf spot statistics

Avalon, Australia, offers a mix of wind swells and ground swells with variable conditions throughout the year. The best months for surfing are typically from May to August, when ground swell contribution peaks at around 30-31%, offering more consistent and cleaner waves. During this period, wind conditions also improve, with good wind days (offshore or light cross-shore) averaging 38-40%. The mean swell size remains steady around 1.4-1.5m, providing manageable yet decent waves for intermediate to advanced surfers. Outside these months, wind swells dominate, particularly from November to March, where they account for 81-87% of the swell mix. Unfortunately, these months also see higher percentages of poor wind conditions (73-79%), making sessions less reliable. April and September are transitional months, with ground swell percentages around 26% and 20%, respectively, and moderate wind conditions. If you’re looking for the most favorable balance of swell quality and wind conditions, the winter months (May-August) are your best bet, though you’ll still want to monitor forecasts closely for those optimal days. The shoulder months (April, September) can also provide decent sessions when conditions align. Overall, Avalon is a spot that rewards patience, with the most consistent setups arriving mid-year.

April at Avalon offers fairly consistent surf conditions with an average swell height of 1.4m and a solid period of 9.5s, ensuring decent energy in the waves. The dominant swell directions are from the east (E, ESE, SE), which account for the majority of rideable waves, particularly in the 1-2m range. This provides a good mix of intermediate-friendly waves with occasional larger sets when ENE or SSE swells push through. Wind conditions are favorable 35% of the time, typically light to moderate from the north or northeast, keeping the surface clean. However, stronger winds from the south or southwest can occasionally create choppy conditions, especially when combined with larger SSE swells. Overall, April delivers a reliable mix of surf, best suited for intermediate surfers on easterly swells with offshore winds, though patience may be needed for optimal sessions.
