Little Wanganui - surf spot statistics

Little Wanganui on New Zealand’s South Island offers consistent year-round surf, with ground swells dominating (71-84%) and minimal wind swells or flat days. The best months for surfers are generally from May to September, when swell size peaks (2.1-2.3m) and offshore wind conditions improve. June and July stand out with the highest percentage of good winds (35-38%) and reliable swell energy. Winter also sees the most favorable balance of clean conditions and solid waves, though the swell can be powerful and better suited for experienced surfers. Spring (September-November) still delivers solid waves (1.9-2.3m) but with worsening wind conditions, while summer (December-February) brings smaller swells (1.6-1.8m) and fewer clean days (23-33% good winds). The spot rarely has no swell, making it dependable, but autumn and winter provide the optimal mix of size, consistency, and cleaner winds. For surfers seeking quality overhead waves with minimal onshore interference, mid-year is the prime window.
