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.
