Westport Breakwater - surf spot statistics

Westport Breakwater in New Zealand is a consistent surf spot with reliable ground swell throughout the year, rarely experiencing days without swell. The best months for surfers typically align with the Southern Hemisphere winter and early spring (May to September), when swell size peaks at an average of 2.2-2.4 meters, offering powerful and clean waves. During this period, ground swell dominates (80-84% of the time), ensuring quality wave energy. Wind conditions are most favorable in June and July, with 38-39% of days providing good offshore or cross-shore winds, though overall bad wind conditions still prevail (61-63% in these months). From October to December, swell consistency remains high, but wind quality deteriorates further, dropping to 28-31% good wind days. The summer months (January to March) see slightly smaller swells (1.7-1.8m) and the worst wind conditions, with only 33-37% of days being surfable due to onshore winds. While the spot works year-round, experienced surfers will find the largest and cleanest waves from May to September, particularly June and July, despite the challenging winds. The shoulder months of April and October can also deliver strong swells but require more wind luck. Winter remains the prime season for size and consistency, while summer offers smaller, less reliable waves with poorer winds.

December at Westport Breakwater offers solid surf conditions with an average swell height of 1.9m and a healthy period of 11.7s, indicating well-formed, powerful waves. The swell is predominantly from the WSW direction, contributing to 21.87% of waves in the 1-1.5m range and 17.69% in the 1.5-2m range—ideal for intermediate to advanced surfers. Larger sets (2m+) are frequent, with WSW, W, and WNW swells driving the best sessions, though occasional bigger days (2.5m+) add variety for those seeking heavier waves. Wind conditions are a mixed bag: 29% of the time, winds are favorable (typically light NNE to NW breezes under 20kph), but stronger winds from the N/NE or SW can create choppiness. Early mornings often see cleaner conditions before afternoon sea breezes pick up. For consistent, high-quality waves, target WSW swells with light offshore or cross-shore winds (NNE-NW). Be prepared for varied conditions, as wind shifts and swell size can change rapidly.
