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.

In June, Windang Island offers decent surf conditions with an average swell height of 1.5m and a favorable period of 9.6s, providing well-formed waves. The primary swell direction is predominantly from the southern quadrants (SSE, S, and SE), which make up a significant portion of the wave distribution—particularly in the 1-2.5m range, suggesting consistent, rideable waves. Wind conditions are somewhat variable, with ideal offshore or light cross-shore winds occurring 31% of the time. However, winds from the west and southwest can be onshore and stronger (20-40kph), potentially creating chop, especially during active frontal systems. The best surf is likely on days with SSE/S swells and light SE/ESE winds, ensuring clean faces. While not epic, June provides reliable mid-sized surf with enough good days to make it worthwhile for intermediate to advanced surfers.
