The Lowdown

G'day, Rusty here. Let’s break down what’s cookin’ at Molhes de Mampituba for the next couple weeks. This river and jetty break gets a good exposure to the swell, and it’s a fairly consistent spot, so there’s plenty to chew on.

Water’s about 17° – dead average for this time of year, no big surprises there. Kicking off Sunday the 16th, we’ve got a 2.4m swell from the ENE, short period of 8 seconds, and energy at 1235. The cross-off breeze keeps it clean, but it’s a bit touch-and-go, so not the main event.

Monday the 17th morning is solid: 2.2m ENE swell, 8-second period, clean with that cross-off wind. Energy’s at 1070, plenty for the jetty to work with. Good for the experienced surfer.

But the real highlight? Monday the 24th of August. A 2.3m SSE groundswell with a 13-second period – that’s proper power, energy at 1718. Light cross-off wind from the SW, so it’ll be glassy and clean. This is expert-only with that size, but the jetty will handle that long-period energy and give you some serious barrels. Crowds are often, so be ready to share.

Tuesday the 25th is another solid option: 1.7m SSE swell, 14-second period, energy at 1108, with light cross-off winds. Clean again, but again, the longer period makes the wave racey on the jetty – better for those who know their way around.

After that, it’s a slow fade. The last week of August is messy with onshore winds and weak energy. Thursday the 27th morning has a 1.7m ENE swell, short period, with clean cross-off wind, energy at 650 – a decent quickie, but nothing compared to the 24th.

Your top bet is the 24th Monday morning – that Southern Ocean groundswell, glassy wind, and a jetty that’ll turn it into gold. Get on it.

Rusty.
