The Lowdown
Alright, Rusty here, and I’m looking at the forecast for Riviere Noire Harbour sandbar. It’s a slow start, but there’s some serious juice coming if you’re willing to wait.
The first week, from Sunday the 2nd through the 7th, is quiet. The swell is small, mostly under 3 feet, with weak energy in the hundreds. The wind is offshore, keeping it clean, but there’s just no power. The water is a touch warmer than normal at 77° on the 2nd, but that’s about it. It’s a flat spell, not worth getting wet for.
Then things pick up. Saturday the 8th is a solid early option, with a 4-foot swell from the SSW, a long period of 18 seconds, and clean offshore wind. The energy jumps to 1123, and it’s looking very good. The sandbar likes that SW direction.
The real highlights are Wednesday the 12th and Friday the 14th. On the 12th, we’ve got excellent conditions for experienced surfers. The morning has 5-foot swell from the SSW at 15 seconds, with a gentle offshore breeze. Energy is at 1836. The afternoon bumps up to 6 feet. That’s a powerful, clean swell.
But the big one is Friday the 14th. The morning brings 7 feet, and the afternoon hits 7 feet from the SW, with a period of 17-18 seconds and energy over 2500. This is a very strong, long-period groundswell. The wind is offshore and clean. This is big, powerful, and consistent. The 7-foot swell is in the expert-only zone. It’s going to be a charging day.
The weekend, the 15th and 16th, stays solid with 7 to 8 feet, but the period drops a bit. Still excellent for strong surfers, but the 14th is the peak.
So, the call: wait through the flat first week. The best on offer is the 12th for a clean, solid swell, and the absolute standout is the 14th of August for the biggest, most powerful groundswell of the run. That’s the one for the experienced crew.
Rusty.
