The Lowdown
Right, grab a coffee, mate. Rusty here with a look at the next couple of weeks.
Alright, let’s be straight with you. The whole 16-day window is a write-off for decent surf. The swell is there, but the wind has got it all chopped up. The predominant wind is onshore and fresh, blowing straight into the break from the southeast or east-southeast, and that’s just killing any chance of clean waves. You’re looking at a solid two-week stretch of poor surf conditions with no let-up.
We’ll start at Anse Bougainville. The water’s a touch warmer than normal for this time of year at 82°. The swell hangs around the 5 ft to 8 ft range all the way through to the 28th of September, mostly from the SE or SSE. The combined energy is moderate to strong, hitting a peak of 1338 on the 18th, but with that constant onshore wind, it’s just a mess. The period is mostly around 8-10 seconds, so it's a mix of windswell and short-period groundswell, which usually means fat, unappealing lines.
Even when the swell jumps over 7 ft, it’s not worth getting excited about. On the 17th and 18th of September, the energy hits four digits and the period stretches to 11 seconds, suggesting more push, but the wind doesn’t let up. The break is exposed to the swell, so it’s catching everything, but it’s catching it all wrong. It’s just messy, lumpy, onshore slop. Honestly, if you’ve got a kite, this setup looks far more interesting than paddling out. The only slight reprieve is a few cross-onshore periods on the 19th, but that’s still not good.
There are no standouts here. Not one session gets a pass. The only thing I can say is that it tends not to stay this poor forever, but for the next 16 days, save your energy and do something else. The surf is staying poor all the way through to the 28th of September.
