The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Riviere Noire Harbour.
We’re starting off with a bit of a slow burn, but the second half of the window has some real juice. The first few days are all about consistent, clean offshore wind, but the swell is just too small to get excited about. The real standout is hands down the afternoon of Saturday, 5th September, and the morning of Tuesday, 8th September is a monster for the brave.
For the first few days, from Sunday the 30th of August through to Friday the 4th of September, it’s mostly a waiting game. The wind is offshore and clean, but the swell is tiny, often below 3 ft, with weak energy. The water is a touch warmer than normal for this time of year, sitting at 77°.
The first real grunt shows up on Saturday the 5th of September. The morning has a solid 6 ft SSW swell with a 15-second period, and the combined energy (1158) is moderate. But the afternoon is the pick of the first week. The swell drops a touch to 5 ft from the SW, but the period is a very long 14 seconds, and the wind drops to a light 6 mph offshore. The water will be glassy clean. The energy jumps to 1981. This is a beautiful window for an intermediate surfer. The direction is SW, which is exactly what this sandbar wants.
Sunday the 6th and Monday the 7th of September are also good, with clean 4 ft to 5 ft swell and light winds, but the crowd factor is a possibility here, so get there early.
Now, Tuesday the 8th of September is a whole different story. The morning shows a massive 15 ft south swell with a 16-second period, and the combined energy is a whopping 10033. That is serious energy. The wind is cross-off and light. This is only for experts. The swell is too big for this break, so unless you are a seasoned charger, stay on the beach. The afternoon drops to 10 ft, still massive, and the energy is 6846. Only for the best.
Wednesday the 9th and through to the 11th of September keep the swell up in the 5 ft to 8 ft range, with solid SSW and S swells, and offshore winds. The energy stays moderate to strong. The water is still a touch warmer than average.
The final weekend, Saturday the 12th and Sunday the 13th of September, sees the swell drop back to a more manageable 4 ft to 5 ft, with very clean conditions. Sunday morning the 13th is glassy, with a 5 ft SSW swell. That’s a beautiful, clean morning for a long session.
So, the best on offer is the afternoon of Saturday the 5th of September for its clean, long-period groundswell and light offshore wind. The second standout is the morning of Sunday the 13th of September for the glassy conditions. The 8th of September is a big-wave day for experts only.
Rusty out.
