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.

September at Superbank offers fairly consistent but modest surf conditions, with an average swell height of 1.4m and an 8.7s period, suggesting mostly small to mid-sized waves with reasonable power. The swell direction is predominantly from the east to southeast (E, ESE, SE, SSE), contributing over 50% of the swell activity, with the best-quality waves likely coming from these angles. SSE swells in particular bring the largest waves, with 9.45% of waves in the 1-1.5m range and 4.7% in the 1.5-2m range, occasionally pushing bigger (1.81% 2-2.5m, 0.1% over 2.5m). Wind conditions are a limiting factor, with only 24% of the time offering ideal wind conditions, typically light offshores from the west or northwest. However, northerly and southerly winds are more common, creating cross-shore or onshore chop, especially at higher speeds (20-30kph+). Surfers can expect rideable waves most days, but the best sessions will rely on favorable SSE swells paired with light WNW/NW winds for cleaner faces. Consistency is decent, but bigger or cleaner days are less frequent.
