Bogan River - surf spot statistics

Best Surf Season (March - May)

Autumn delivers the sweet spot at Bogan River. As the Southern Ocean cranks up its storm machine, average swell heights climb to a solid 1.6–1.9m with long-period energy (12.8–13.0s) that really wraps into this WSW-facing beach. The wind gods also play nice, with offshore breezes from the NE to ESE quadrant blowing 26–28% of the time. This combo means more clean, rippable walls and fewer blown-out messes. March through May is when you want to book your trip.

Fair Surf Season (June - August)

Winter keeps the size pumping at 1.9m, but the trade-off is a drop in ideal wind percentages to 20–23%. The prevailing SW swell continues to pour in, but onshore winds from the W and SW become more frequent, especially during frontal passages. When a high-pressure system parks over the Tasman Sea, it can deliver those coveted offshore conditions – just be ready to work around the lows. The waves retain their power and period (12.7–13.0s), so when the window opens, it fires.

Low Surf Season (September - February)

Spring and summer bring a mixed bag. Swell heights gradually drop from 1.9m in September to 1.4m in January, and the ideal wind percentage bottoms out at 15–19% in late spring. September through November still have size but are plagued by onshore SW winds, making it hard to find clean conditions. December through February sees smaller surf (1.4–1.5m) with shorter periods (11.7–12.0s), though the offshore wind window opens a bit more in February (27% ideal). If you're after fun-sized waves without the crowd, early summer can offer sneaky fun, but don't expect the consistent quality of autumn.

March: Peak Autumn Fire

March marks the onset of prime season. Average swell height jumps to 1.6m with a period of 12.8s, indicating stronger, longer-period energy. SW swell dominates at 58.2%, but there's also a notable chunk of WSW (20.2%) and a hint of W (5.0%). The distribution of swell heights shows a solid core of 1–1.5m (24.1%) and 1.5–2m (15.9%) – perfect for carving. Offshore wind percentages hold at 28%, with ENE (9.2%) and NE (6.7%) leading. The Southern Ocean is firing, and the subtropical ridge often positions itself to deliver light offshore flow. This month consistently delivers the best combination of size, power, and clean conditions.
