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.

October at Windang Island offers fairly consistent surf with an average swell height of 1.4m and a decent period of 8.6s, providing rideable waves most of the time. The primary swell directions are from the northeast to southeast, with the highest frequency of waves (1-2.5m) coming from ENE, E, SE, SSE, and S. These swells are cleanest when paired with favorable offshore winds, which occur 26% of the time. Wind conditions are most problematic when northerly or southerly, as they tend to be onshore or cross-shore, creating chop. However, lighter easterly or westerly winds (under 20kph) can occasionally clean up the conditions. Expect a mix of smaller (0.5-1.5m) and mid-sized waves (1.5-2.5m), with occasional bigger sets, particularly from the southern quadrant. While not always perfect, October delivers enough quality days to make it worthwhile for intermediate to advanced surfers, especially when the wind cooperates.
