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.
