The Lowdown
Alright folks, Rusty here. Let’s get stuck into this one. We’re looking at a solid run of surf coming up at Riviere Noire Harbour, a sandbar break that’s fairly exposed to the swell. The water’s sitting at 76°F, which is a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home.
The action kicks off on Wednesday afternoon, August 12th, with a clean 4ft swell from the SW and a light cross-off breeze. It’s not huge, but it’s clean and rideable. The energy’s moderate, so you’ll feel it. Thursday, August 13th, is lovely with a glassy morning and 3ft SW swell, turning glassy in the afternoon with a 3 mph breeze. Perfect for a cruise.
Then things start to fire up. Friday, August 14th, we see a jump to 6ft SSW swell, light offshore winds, and strong wave energy. That’s a really nice, clean wave for intermediates. But the real standout? Saturday, August 15th. Saturday morning delivers a 6ft S swell with a 21-second period – that’s proper groundswell, long-period energy, and combined swell energy is through the roof. It’ll be breaking with power and shape, best for experienced surfers. Saturday afternoon gets even bigger – 10ft SSW, 19-second period, moderate offshore winds, and energy going huge. That’s for expert surfers only, but it’s exceptional. This period has a very long swell period, so keep in mind that at a sandbar, those long lines can sometimes close out, but with offshore winds, it’ll be well worth it.
Sunday, August 16th, stays big and clean with 10ft SSW and 8ft SSW in the afternoon, all offshore winds. The energy remains massive. Monday, August 17th, drops to 6ft but still clean and offshore. The wind picks up a bit through the week, but it stays offshore, keeping the surface clean. There’s a gap from around August 21st where the swell dips to 3ft, but it’s not a dead zone – just a lull.
Now, looking further out, the second week has some big promise. Saturday, August 22nd, has 10ft SSW swell with 19 mph offshore winds, but the energy is massive. It’s a wild one, so only for the brave. Sunday, August 23rd, is also 10ft with a lighter breeze, and the energy is still massive. The standout in the second week looks like Tuesday, August 25th afternoon, with 8ft SSW, 16-second period, strong offshore winds, and huge energy – excellent for experienced surfers. Then Wednesday, August 26th, pushes 12ft SSW, which is huge and definitely expert territory. Crowds are possible here, so get in early.
Overall, Saturday, August 15th, is your best bet – a true standout with that long-period groundswell, clean offshore winds, and massive energy. If you’re an expert, Saturday afternoon or the 25th afternoon are also golden. For the rest, there’s plenty of fun, clean waves on offer.
Rusty.
