South Wall Ballina - surf spot statistics

South Wall in Ballina, Australia, offers a mix of ground and wind swells throughout the year, with no completely flat periods. The best months for surfing are typically between May and August, when ground swells dominate (52-61% of the time) and wind conditions improve, particularly in June, July, and August when good winds occur 48-53% of the time. These months also provide consistent swell sizes averaging 1.2-1.5m, making them the most reliable for quality surf. Outside this window, conditions are less favorable, with higher percentages of wind swells (up to 73% in November) and stronger onshore winds, particularly from January to April and September to December. The worst wind conditions occur in February (78% bad winds) and December (71% bad winds), while swell quality is weaker in late spring and early summer. For surfers seeking cleaner, more powerful waves, the winter months (June-August) are ideal, offering a balance of favorable swell direction and lighter winds compared to the rest of the year.

In January, South Wall Ballina experiences decent surf conditions with an average swell height of 1.3m and a solid period of 9.7s, indicating well-formed, powerful waves. The swell direction is predominantly from the east (E, ENE, ESE) with a notable frequency in the 1-1.5m range (20.16% for E). Larger swells (1.5-2.5m+) are less common but occur mostly from the SE to SSE, offering occasional punchy sets for experienced surfers. Wind conditions are variable—only 32% of the time are winds ideal (likely light offshores or sideshores from the W-NW sector). However, moderate NE to SE onshore winds are frequent, which can create chop, especially when combined with larger swells. The best sessions will likely be early mornings when offshore winds are more likely or during periods when ENE/ESE swells coincide with lighter winds. Overall, January provides a mix of surfable days, but wind management is key to scoring clean waves.
