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.

March at Superbank offers generally solid surf conditions with an average swell height of 1.7m and a decent period of 9.2s, providing well-formed, powerful waves. The swell is predominantly E to SE, with the largest contributions coming from these directions—particularly in the 1-2.5m range—making for consistent, high-quality rides. However, wind conditions can be hit or miss: only 33% of the time is the wind truly ideal (likely light offshore or cross-offshore). The worst case is onshore SE to SSE winds, which can be moderate to strong (10-30+ kph) and disrupt wave quality. While smaller swells (0.5-1.5m) are frequent, the spot handles bigger days (1.5-2.5m) well, especially when ENE to E swells align with favorable winds. Expect some extended flat spells from W to NW wind directions, but overall, March delivers a mix of good surf days, especially when wind and swell direction cooperate.
