Anse Bougainville Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what we’ve got on the menu for Anse Bougainville.

Honestly, it’s a pretty rough run ahead. The set-up at Anse Bougainville is a consistent reef break that needs a SE offshore wind to clean up, but for the next two weeks we’re looking at onshore winds almost non-stop. That means the water will be messy and lumpy, not the smooth, groomed lines you want. With water temps sitting at about 80°F right now, that’s just about bang on average for this time of year, so no weird surprises there.

The whole first week is pretty much a write-off. Starting from Thursday 3rd, we’ve got solid 8 ft swell from the SE with a moderate 10-second period, and plenty of energy (combined energy around 1339), but it’s all blown out with that fresh SE wind hitting 19 mph. Same story through Friday and into the weekend—wave heights drop a bit to 6 ft, but the wind stays on it.

By Monday 7th afternoon, things get a little less terrible. The wind eases to just 3 mph from the SSE, but it’s still onshore, and the swell drops to 6 ft. The score is still a very marginal “maybe,” not anything to get excited about. The rest of that week stays locked in with onshore flow and moderate-sized, short-period junk.

You do get a little pulse of long-period groundswell around Wednesday 9th and Thursday 10th, with swell periods of 16 and 15 seconds from the S. That would normally be mouth-watering for this reef, as long-period S swell loves a setup like this. But again, that fresh SE wind is right on it, trashing the surface (combined energy 928–1432). If the wind ever clocks offshore, it would be magic, but it doesn’t look like it will.

The second week doesn’t offer much hope either. More short-period, onshore slop through to the 16th. Then, on Thursday 17th September, we finally see a massive spike in energy—combined energy jumps to 2982 with a 5 ft swell from the SSW at a very long 21-second period. That is a serious groundswell, the kind that wraps in with real punch. But once again, it’s blown out by a 16–19 mph SE wind. That’s a heartbreaker. The same deep energy lingers into Friday 18th (combined energy 1765), but same wind story.

If you were hoping for a kite session, this might actually be your window. With moderate to fresh onshore winds and waist-to-chest high, lined-up swell, that set-up looks way more interesting for a kite than trying to paddle into chop.

So, best of the lot? Honestly, the only standout on the board is that Thursday 17th and Friday 18th combo. The SSW groundswell is pure quality (21 seconds is as long as it gets), and the size (5 ft) is super manageable for intermediate and above. If the wind was offshore, it would be a dream. But as it is, it’s a “keep an eye on it” call—if the forecast shifts and the wind backs off or turns offshore, that window could turn into the best surf we see in the whole 16 days. Until then, I’d leave the board at home.
