North Wall Ballina - surf spot statistics

North Wall Ballina in Australia offers varied surf conditions throughout the year, with the best months typically aligning with the winter season when ground swells dominate and wind conditions improve. From May to August, the percentage of ground swell increases significantly, peaking in July at 32%, while wind swell decreases. These months also see better wind conditions, with July offering the highest likelihood of favorable winds at 36% compared to the rest of the year. The mean swell size remains relatively consistent, hovering around 1.5 to 1.7 meters, providing manageable yet powerful waves. Outside of winter, the spot becomes more wind-swell dependent, particularly from November to February, when the ground swell drops below 20% and onshore winds frequently degrade conditions. Late autumn and early winter (May to July) are optimal for surfers seeking cleaner, more organized waves, while summer months tend to be less reliable due to higher wind swell influence and poor wind alignment. If you prioritize quality over consistency, target the May-August window for the best balance of swell energy and cleaner conditions.

In September, North Wall Ballina offers decent surfing conditions with an average swell height of 1.5m and a solid period of 9.0s, ensuring well-formed waves. The dominant swell directions are from the south and southeast, with SSE swells contributing the most consistent and surfable waves (9.91% in the 1-1.5m range and 7.31% in the 1.5-2m range). These swells often produce clean, powerful lines ideal for intermediate to advanced surfers. E and ESE swells also provide some good sessions, though less frequently. Wind conditions are favorable 28% of the time, with lighter offshore or cross-shore winds from the west and northwest being optimal. However, northerly and southerly winds can occasionally bring onshore chop, especially at higher speeds (20-30kph+). Overall, September delivers a mix of manageable swells and occasional high-quality days, though wind interference means selective timing is key for the best sessions.
