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 March, Windang Island offers surfable conditions with an average swell height of 1.5m and a decent period of 9.1s, suggesting relatively clean and well-spaced waves. The primary swell directions are from the ENE, E, and SE, with the highest frequency of rideable waves (1-2.5m) coming from these sectors. About 23% of the time, the wind is favorable (typically light offshore or cross-shore), though prevailing winds are more commonly from the north to northeast at moderate speeds (10-30kph), which can cause chop, especially in stronger northerly flows. Sessions are most consistent with swells in the 1-2.5m range, with ENE, E, and SE swells providing the best shape. Larger days (over 2.5m) are rare but occur mostly with southerly swells, though they may come with stronger onshore winds. Expect a mix of surfable days with some clean sessions when winds align, but be prepared for occasional wind-affected conditions.
