Bogan River - surf spot statistics

Bogan River in New Zealand benefits from consistent ground swells throughout the year, with minimal periods of no swell—never exceeding 1% in any month. The best surf conditions typically occur from March to September when ground swell dominance is highest (83–91%) and average swell sizes peak at 1.7–2.1m, offering more powerful and reliable waves. March stands out with 91% ground swell, 1.7m mean size, and slightly better wind conditions (32% good winds) compared to later months. However, wind conditions become progressively worse from April onward, with good wind days dropping below 30% and reaching their lowest (18–20%) in October–November. Summer months (December–February) provide smaller swells (1.5–1.6m) and higher wind swell influence, with February offering marginally better wind conditions (33% good winds) than other summer months. While winter delivers larger, cleaner swells, the frequent onshore winds reduce ideal surfing days. Advanced surfers may prefer late autumn to early winter (May–July) for bigger waves, though patience with wind conditions is necessary. Mid-to-late autumn (March–April) strikes a balance between solid swell size and moderately better wind chances, making it the most favorable window overall.

Bogan River in July offers consistent swell conditions with an average height of 2.1m and a solid period of 13.1s, indicating powerful, well-spaced waves. The dominant swell direction is WSW, contributing to 18.4% of waves in the 1-1.5m range and 19% in the 1.5-2m range, making it the most reliable for surf. Larger waves (2-2.5m) are also frequent, particularly from WSW (12.9%) and W (3.2%), providing good opportunities for experienced surfers. Wind conditions are less favorable, with only 23% ideal for surfing, often blowing from the west and southwest at moderate speeds (10-30kph), which can create chop on the face. However, early mornings or wind shifts may offer cleaner conditions. Overall, July delivers solid, powerful surf with a mix of mid-sized and larger waves, though wind can be a limiting factor. Advanced surfers will find the most potential, especially on WSW swells with lighter offshore winds.
