Snapper Rocks - surf spot statistics

Snapper Rocks is a world-class right-hand point break that works best with solid ground swells and offshore winds. The data shows that the most consistent ground swells occur from May to August, peaking in July at 29%. These months also offer the most favorable wind conditions, with May having the highest percentage of good winds at 37%. While the mean swell size hovers around 1.5-1.7m throughout the year, the quality of the waves improves during this period due to the higher proportion of clean, powerful ground swells and fewer onshore wind disruptions. In contrast, the summer months (November to February) see a dominance of wind swells (84-88%), which are less ideal for high-performance surfing at Snapper. Additionally, bad wind conditions plague this season, with December suffering the worst at 79% unfavorable winds. March and April serve as transitional months, with gradually improving ground swell percentages (20%) and slightly better wind conditions than summer, though still inconsistent. For the best balance of swell power, ground swell dominance, and cleaner winds, surfers should target the autumn and winter months (May to August), with June and July standing out as particularly reliable. The drop in swell size from August onward, combined with increasing wind chop, makes early winter the premium window for those seeking long, barreling waves at this iconic spot. The rest of the year remains surfable but is far less predictable and often compromised by short-period wind swells and onshore flow. Advanced surfers will prioritize the May-July window for serious sessions, while those tolerant of softer conditions can still find opportunity in late autumn or early spring.

December at Snapper Rocks offers solid surfing conditions with an average swell height of 1.5m and a decent period of 8.4s, ensuring well-formed waves. The swell direction is predominantly from the east and southeast, with the largest waves (1.5m–2.5m) coming from E (15.13% at 1-1.5m, 7.30% at 1.5-2m) and ESE (8.62% at 1-1.5m, 3.27% at 1.5-2m), providing consistent, clean, and rideable surf. Smaller but still surfable swells (1-1.5m) are frequent from ENE, SE, and SSE. Wind conditions are favorable 21% of the time, with the best scenario being light offshore winds from the west or northwest, though these are rare. More commonly, easterly and northeasterly winds prevail, which can be onshore and disruptive at higher speeds (20-30kph range), particularly from N, NNE, and NE. Stronger southerly winds (SSE, S) can also create choppier conditions. Overall, December delivers a mix of good waves, especially on days with lighter winds or when swells align with offshore breezes, making it a promising month for experienced surfers.
