Windang Island - surf spot statistics

Windang Island in Australia offers consistent surf conditions year-round, but the best months for surfers typically fall between April and July. During this period, the percentage of ground swell increases significantly, peaking in June at 30%, while wind swell dominance decreases slightly compared to other months. Ground swells typically produce cleaner, more organized waves, making these months favorable for quality surf. Wind conditions also improve from April onwards, with good wind days occurring around 30-33% of the time—higher than in summer months—though onshore winds remain a frequent challenge. The mean swell size stays relatively stable at 1.5m, providing decent wave energy without being overwhelming. Outside this window, particularly from November to March, the surf is heavily influenced by wind swell (85-88%), which often results in choppier, less predictable conditions, and onshore winds prevail more than 80% of the time. While Windang Island is surfable year-round, mid-autumn to mid-winter (April-July) offers the most reliable combination of swell direction, wave quality, and manageable wind conditions for intermediate to advanced surfers.

September at Windang Island offers fair to good surfing conditions with an average swell height of 1.4m and a decent period of 8.8s, ensuring relatively clean and organized waves. The dominant swell directions are from the SSE, S, and SE, which provide the most consistent and rideable waves, particularly in the 1–2.5m range. Swells from these directions account for a significant portion of the month’s surf, with occasional larger sets over 2.5m, though they are less frequent. Wind conditions are a mixed bag—ideal offshore or light winds occur 30% of the time, mainly from the W to NW early in the day, but moderate onshore winds from the NE to E can degrade conditions, especially in the afternoons. Surfers should target mornings when winds are lighter and swells are most favorable from the southern quadrants. Overall, September delivers workable waves, but timing sessions around wind shifts will maximize quality.
