The Lowdown

G’day, Rusty here, and I’ve been staring at the charts for your local stretch around Molhes de Mampituba (Rio Grande do Sul). This is a river/jetty setup that’s fairly consistent, and it’s exposed to the SE – so when it lines up, it can fire. Right now, we’ve got a bit of a slow start, but there’s some proper gold hiding in the second half of the week if you’re willing to wait for it.

The first real action worth paddling out for kicks off on Tuesday morning, 25 August. We’ve got a clean 5 ft swell rolling in from the SSE with a 12-second period – that’s a nice groundswell, not too short, not too long. The combined swell energy is moderate at 680, and with a light cross-off breeze from the NNE at 6 mph, the surface is going to be clean. The water’s sitting at 61°, which is a bit colder than normal for this time of year (anomaly of -2°F), so grab a decent wetsuit. Tuesday morning is your best bet early on, with very good surf conditions. The afternoon gets a bit messy with a cross-shore breeze, so stick to the early sesh.

Now, Wednesday morning, 26 August is where it gets interesting. The swell bumps up to 7 ft from the SSE, period stretching to 14 seconds – that’s proper groundswell energy. The combined energy jumps to 1758, which is strong. Light NE breeze at 6 mph keeps it clean. This is excellent surf for experienced surfers – it’s pushing over 5 ft, so beginners might find it a handful. The jetty setup here will handle that longer-period swell well, giving you some nice lines. This is one of the true standouts of the forecast.

Thursday morning, 27 August sees the swell drop back to 5 ft from the SSE, still with decent 13-second period, but the wind is cross-shore at 9 mph, so it’s not as clean. The energy is moderate at 1008. It’s surfable but not as good as Wednesday.

Then comes Friday morning, 28 August – another standout. The swell swings to the ENE at 7 ft, but the period is short at 8 seconds, which means it’s windswell, not groundswell. But here’s the kicker: the wind is glassy – completely dead calm from the north at 3 mph. That means the surface will be like a mirror. The combined energy is moderate-strong at 1133. This is only for experts at over 8 ft? No, it’s 7 ft – still big enough that beginners should sit it out, but for experienced surfers, those clean, peaky waves will be a blast. The short period means it’ll be a bit crumbly, but glassy conditions make up for a lot.

After Friday, things get inconsistent. Saturday morning, 29 August offers a smaller 4 ft from the east with light offshore wind (WNW at 6 mph), giving clean waves, but it’s weak energy at 248. Sunday morning, 30 August is similar – 4 ft from the east, clean but small. Monday, 31 August is poor with onshore wind and messy conditions.

Tuesday, 1 September sees another bump – 7 ft from the SSE in the morning, but it’s onshore wind (SSE at 9 mph) and the period is short at 8 seconds, so it’ll be choppy and difficult. Not one to get excited about. The afternoon is similar with 7 ft.

There’s a gap of a few days with no real standouts until Saturday morning, 5 September, where we get a clean 6 ft swell from the NE with a short 6-second period and light cross-off breeze. The energy is moderate at 444. It’s surfable but nothing special. Sunday morning, 6 September is similar – 5 ft from the ENE, clean, but short period.

Then on Monday morning, 7 September, we get a tiny 4 ft from the ENE with a 10-second period and glassy conditions (SSE at 3 mph). Clean but small.

Overall, the best on offer is Wednesday morning, 26 August (7 ft SSE, 14 sec, light offshore, strong energy) and Friday morning, 28 August (7 ft ENE, glassy, moderate-strong energy). Get on those. The rest is mostly small or choppy.

Rusty, signing off.
