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.

May at Gunnamatta typically offers fair to good surf conditions with a consistent groundswell. The average swell height is 1.4m, supported by a long 13.0s period, providing well-spaced, powerful waves. Swell direction is predominantly SW (22.76% in 0.5-1m, 27.76% in 1-1.5m) and SSW (peaking at 0.95% in 1.5-2m), ensuring clean, organized waves with decent size and shape. Smaller contributions from WSW and S swells add variety. Wind conditions are less favorable, with only 26% of days offering ideal offshore or light cross-shore winds (typically from the N/NE quadrant). However, moderate to strong onshore WSW-WNW winds are common (20-30kph range), which can degrade wave quality. Overall, spring sessions are best timed around early mornings or wind lulls, with the most reliable waves arriving from the SW-SSW sector. Expect chest-high to overhead waves on better days, though wind management is key.
