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 January, Windang Island delivers average surf conditions with a mean swell height of 1.5m and a decent period of 8.4s, suggesting fairly clean and organized waves. The swell predominantly arrives from east to southeast (ENE, E, SE), with the most consistent energy in the 1-2m range, offering surfable waves most of the time. Larger sets (2-2.5m) are less frequent but present, mostly from ENE and SSE directions. Wind conditions are variable, with only 18% of the time being ideal (typically light offshore or side-offshore). Northerly and northeasterly winds can be problematic when stronger (20-40kph), causing chop, while lighter easterly or southerly winds improve conditions. Expect the best sessions early mornings before winds pick up. Overall, January provides moderate surf opportunities, though wind quality and consistency are limiting factors. Advanced surfers can still score good waves, especially on days with cleaner wind alignments.
