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.

February at Duranbah offers a mix of surfable conditions, though consistency and ideal winds can be hit or miss. The average swell height of 1.7m with a 9.0s period suggests mostly mid-sized waves, offering decent rides for intermediate to advanced surfers. The majority of swell energy comes from the E to SE (peaking in the 1-2.5m range), with ESE and E directions dominating—these angles typically provide the cleanest and most rideable waves at this break. However, smaller or weaker swells (under 1m) are less frequent, meaning most days have something to work with. Wind conditions are the bigger variable: only 16% of the time are winds ideal (likely light offshore or cross-offshore from the W/NW quadrant). Unfortunately, E/SE winds—which are onshore and can degrade wave quality—are more prevalent, occurring roughly 30-40% of the time, especially in the 10-30kph range. Stronger S/SSE winds (20-40kph) also appear occasionally, ruining shape. The takeaway: February delivers surf semi-regularly, but morning sessions or days with W/NW wind influence will be the prime windows. Patience and flexibility are key—when it’s good, it’s fun, but expect some choppy or marginal days mixed in.
