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.

August at Windang Island offers a mix of surfable conditions, though consistency varies. The average swell height is 1.4m with a decent 9.1s period, providing enough energy for quality rides, particularly when swells align with the break. The dominant swell directions are SSE, S, and SE, which produce the most frequent and sizable waves—SSE swells, in particular, contribute to 9% of waves in the 1–1.5m range and 3.8% in the 1.5–2m range, offering the best potential for overhead sets. However, wave quality can be compromised when winds turn onshore (E to SE), which occur about 30% of the time at ideal speeds (10–20kph). Offshore W to WNW winds are less frequent but create cleaner conditions when they prevail. Wind is a limiting factor, with stronger S to SW winds (20–30kph) appearing ~20% of the time, often ruining shape. Overall, August delivers rideable waves regularly, but surfers should target early sessions for lighter winds and prioritize SSE swells for the best size and consistency. It’s not a classic big-wave month, but the spot works best for intermediate to advanced riders on the better days.
