Superbank - surf spot statistics

The Superbank in Australia offers consistent surf conditions year-round, but the best months for surfers generally fall between February and June. During this period, ground swell percentages are slightly higher (peaking at 29% in July, though wind conditions worsen), but the key advantage is the relatively favorable wind conditions. February to May provides the best balance, with good wind conditions ranging from 31% to 37%, while bad winds drop to their lowest levels (63-69%). Mean swell size remains steady around 1.6-1.7m, offering solid wave quality. The worst wind conditions dominate from September to December, with bad winds exceeding 76%, making sessions less ideal despite similar swell sizes. Swell consistency is excellent—virtually no flat days—but wind swell dominates the mix year-round, which can lead to less clean conditions compared to pure groundswell spots. For the best experience, target March to May, when wind and swell align most favorably. July and August see higher groundswell influence but trade-offs with poorer winds and slightly smaller waves. Early winter (May-June) can still be good, though winds become less reliable. If you prioritize wave power over wind conditions, late winter (July) offers the highest groundswell (29%), but expect more challenging winds. Overall, autumn (March-May) is the prime window for quality surf at Superbank.

May at Superbank offers solid surf conditions with an average swell height of 1.6m and a healthy period of 9.4s, indicating well-spaced, powerful waves. The most consistent swell direction is from the E to SSE, with the majority of waves falling in the 1-2.5m range—ideal for performance surfing. ESE and SE swells are particularly dominant, delivering clean, mid-sized waves (1.5-2.5m) around 25% of the time, while larger swells (over 2.5m) are rare but possible. Wind conditions are surfable 37% of the time, with lighter NNE to E winds (below 20kph) creating offshore or cross-offshore effects, especially during ESE swells. However, S to SSW winds (10-30kph) are more common, often bringing onshore chop or side-shore texture. The spot handles southerly winds better than many, but optimal days come when high pressure keeps winds light from the north or northeast. Overall, May delivers a mix of punchy beachbreak peaks and longer walls, with the best sessions occurring when mid-period E/SE swells coincide with light offshore winds.
