Duranbah - surf spot statistics

Duranbah in Australia is a surf spot with consistently rideable conditions year-round, but the best months for quality waves and favorable winds fall between May and August. During this period, the percentage of ground swell increases significantly, peaking at 30% in July, while wind swells decrease, providing cleaner and more powerful waves. The average swell size remains steady around 1.5m to 1.7m, offering solid but manageable waves for experienced surfers. Wind conditions also improve in these months, with the highest likelihood of good winds in June and July (36% favorable). Outside this window, from September to April, the spot becomes more wind-affected with a higher proportion of wind swells (up to 88% in November) and less ideal wind conditions (over 80% bad winds in summer months). Swell size slightly drops from September onward, averaging 1.4m, making the waves less consistent and powerful. If you’re looking for the best balance of swell quality and wind, late autumn to mid-winter (May to July) is the prime time, while summer months (December to February) offer smaller, more chopped-up conditions with frequent onshore winds.

In June, Duranbah offers decent surfing conditions with an average swell height of 1.6m and a solid period of 9.5s, providing consistent, well-formed waves. The swell direction is predominantly from the southeast (SSE, SE, ESE), contributing to the majority of rideable waves in the 1-2.5m range, which is ideal for intermediate to advanced surfers. Wind conditions are favorable 36% of the time, with lighter offshore or cross-shore winds from the west and northwest helping to clean up the surf. However, stronger onshore winds from the south and southeast can occasionally make conditions choppy, particularly when swell exceeds 2m. Overall, June is a reliable month for surf at Duranbah, with a good balance of size and shape, though wind variation means selective timing is key for optimal sessions.
