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.

December at Windang Island offers moderately consistent surf with an average swell height of 1.4m and a decent period of 8.2s, providing relatively clean and rideable waves. The swell direction is predominantly from the NE to SE quadrant, with ENE and E directions contributing the most to surfable conditions (1-2.5m range). This aligns well with the beach orientation, producing decent peaks. However, only 20% of the time does the wind align favorably for surfing, as onshore winds from the NE to SSE are common and can create chop. Light to moderate winds (10-30kph) prevail, but stronger gusts occasionally occur from NNE to S, which may deteriorate conditions. Overall, expect a mix of small to mid-sized waves with occasional clean sessions, particularly when winds are light and variable or offshore. Keep an eye on wind forecasts for those ideal windows.
