Gunnamatta - surf spot statistics

Gunnamatta, Australia, is a consistent year-round surf spot with reliable ground swell dominance, averaging between 78-92% across all months, ensuring solid wave energy. The best conditions generally occur from April to September when ground swell contributions peak (87-92%), and mean swell size increases slightly to 1.4-1.6m, offering more power and better-formed waves. However, wind conditions are less favorable during these months, with bad winds (onshore or cross-shore) prevalent 73-82% of the time, particularly from June to September. The trade-off is that cleaner conditions (19-27% good winds) are rare but occasionally align with swell events, making early mornings or protected spots optimal. From October to March, swell size decreases slightly (1.3-1.5m), and wind conditions remain poor (78-81% bad winds), but ground swell consistency remains high (78-88%). The shoulder months of March, April, and October can provide a balance of decent swell and marginally better wind odds (20-27% good winds). Overall, winter (June-August) delivers the most powerful waves but with challenging winds, while autumn (March-May) and spring (September-October) offer a slightly better compromise between swell quality and occasional clean conditions. Surfers should prioritize dawn sessions or sheltered areas to maximize wind opportunities year-round.

August at Gunnamatta offers consistent surf conditions with an average swell height of 1.6m and a solid period of 13.4s, indicating well-organized, powerful waves. The swell is predominantly from the SW and SSW, with the majority of waves in the 1–2.5m range, providing good size and energy for experienced surfers. SW swells dominate, making up nearly 60% of the waves, ensuring reliable surf, though occasional larger sets over 2.5m can occur. Cross-shore or offshore winds are favorable only 18% of the time, so expect variable wind conditions. The most common wind directions are W to NW, often blowing at 10–30kph, which can create choppiness, but early mornings may offer cleaner conditions. Overall, August delivers solid waves with decent power, though wind quality is hit-or-miss—best suited for surfers comfortable with raw, open-beach conditions.
