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 July, Windang Island offers decent surf conditions with an average swell height of 1.5m and a solid period of 9.4s, indicating well-formed and relatively powerful waves. The swell direction is predominantly from the S to SSE, contributing to the most consistent and rideable waves, particularly in the 1-2.5m range. These directions account for the majority of surfable conditions, with a notable percentage of waves in the 1.5-2.5m range, providing good energy for intermediate to advanced surfers. The wind is favorable for surfing 33% of the time, with the best conditions typically occurring when winds are light to moderate (below 20kph) and offshore or cross-offshore, which is most common from the W to NW sectors. However, stronger onshore winds from the S and SE can occasionally degrade wave quality. For surfers seeking reliable waves, mid-sized swells (1.5-2.5m) from the S/SSE are the most promising, offering a good mix of power and shape, though wind conditions will dictate session quality. Overall, July delivers a mix of surfable days, with the best windows occurring when swell and wind align favorably.
