The Lowdown
Alright folks, Rusty here. We’ve got a solid run of swell lining up for Riviere Noire Harbour, so let’s get straight into it.
The water is sitting at a toasty 76.6°, which is a touch warmer than normal for this time of year – you’ll notice it.
The first proper push arrives Monday afternoon (27 July) with a solid 8.2ft SW groundswell, and the period is a whopping 16 seconds. That’s a long-period groundswell packing some serious energy. The combined energy is strong at 3408, so you’ll feel the power. The wind is a light 5 km/h from the south, cross-off, which will keep things clean. This is proper, powerful surf for experienced surfers only. The long period means this will be the kind of energy that lines up beautifully at the sandbar, but with that size and period, it’s not for the faint-hearted.
Moving into Tuesday morning (28 July), the swell drops slightly to 6.6ft but the direction shifts a touch more southerly (SSW), and the period stays long at 14 seconds. The wind is offshore from the east at 10 km/h, making for clean, peeling walls. The combined energy is still very strong at 2496. Tuesday afternoon looks even better to my eye – the swell bumps up to 7.9ft, period jumps to 18 seconds (that’s a very long period groundswell), and the wind is offshore from the ESE at 15 km/h. The energy is massive at 3652. This is the standout of the entire forecast: big, powerful, clean lines for those who can handle it.
Wednesday (29 July) keeps the fun going with 6.9ft SSW swell in the morning, light offshore wind, and very clean conditions. The energy is still strong at 1874. The afternoon sees a bit of rain but the wind stays light offshore, with 6.6ft SSW swell. Still excellent.
Thursday morning (30 July) sees the swell drop to 5.2ft, but it’s still clean with offshore wind. The energy drops to 1281, still moderate. The afternoon gets smaller and a bit more mixed, with a 3.6ft SW swell and a very long 17-second period, but the wind turns cross-off. It’s still surfable but not as punchy.
Friday (31 July) is a beauty – consistent 5.9ft SW swell, with a long 16-second period, and offshore wind all day. Clean, quality waves with moderate energy around 1531-1592. This is a great pick for the weekend start.
Saturday (1 August) holds well with 6.6ft SSW swell, 15-second period, and a moderate offshore breeze. The energy is strong at 1787. The afternoon picks up a bit of wind strength but stays offshore. Good, solid surf.
Sunday (2 August) sees the swell drop a little to 5.6ft, and the wind turns cross-off. The period is still long (14-17 seconds), but the conditions are a bit less tidy. The energy remains moderate around 1880-1997. Still worth a look but not the pick of the week.
After that, the swell fades into the first week of August. Monday (3 August) has 4.9ft SSW swell and offshore wind, but the energy drops to 1186. Tuesday (4 August) gets small – 2.6ft to 2.3ft – and the wind is cross-off. The energy is weak at 423-336. Things are very quiet until Wednesday (5 August) when a new pulse of 3.3ft to 4.3ft SSW swell with a 16-second period arrives, and the energy comes back up to 690-1021. Light cross-off wind, clean conditions. It’s a lull but not a dead stop.
Thursday (6 August) stays small with 3.6ft to 3.3ft SSW swell, light offshore wind, and moderate energy. Good for a longboard or a fun shortboard session.
Then we hit a proper flat spell from Friday (7 August) through to Saturday (8 August) – the swell drops to 2.0ft to 2.6ft, with strong cross-off winds and poor surf conditions. The energy is weak at 450-718. That’s a few days of nothing to shout about.
The next worthwhile pulse hits Sunday (9 August) with a 5.2ft SW swell and a 16-second period, but the wind is a solid 25-30 km/h cross-off. The energy is moderate at 1421, but the wind makes it messy. Not ideal.
Monday (10 August) looks a bit more promising with a 4.6ft to 5.2ft SW swell, and the wind turns fresh offshore at 30 km/h. The period is very long at 18 seconds on the afternoon. The energy is strong at 1493-1901. This is a late-breaking option for the second week, but that wind is strong – it’s clean, but it’s a battle.
Tuesday (11 August) finishes off the forecast with 5.9ft SW
