The Lowdown
Alright, Rusty here. Let’s break down what’s on the cards for the next couple of weeks.
We’re looking at a solid run of surf coming up, but it’s not all clean windows. The best action is definitely going to be in the mornings, and there’s a standout day or two for those who can get out there.
First up, the water temp is sitting about average for this time of year, so nothing unusual there. The main show is Molhes de Mampituba, a river/jetties setup that’s fairly consistent. It’s exposed to swell, and the optimum direction is from the SE.
Thursday morning, 27 August is a solid start. We’ve got a 5ft SSE swell churning in with a 13-second period, which is a nice long-period groundswell. The wind is NNE at 9 mph, blowing cross-offshore, which is perfect for keeping the waves clean. The combined energy is moderate at 951. This is a very good bet for the keen surfer.
The next real highlight is Monday morning, 31 August. Waves are pushing 7ft from the ESE with an 8-second period. The wind is dead calm, glassy conditions. The combined energy is strong at 1001. This is excellent surf for experienced surfers – the size is getting up there, so it’s not for beginners. It’s a standout.
Looking further ahead to Thursday morning, 10 September, we get another clean morning. A 5ft S swell with a 10-second period, and a light NNE breeze at 3 mph swinging cross-off. The energy is moderate at 478, and the conditions are clean. A very good option.
And then, Friday morning, 11 September is a big one. Swell is 5ft from the SSE, long period at 12 seconds. Wind is light NE at 6 mph, cross-offshore. The combined energy jumps to a strong 1184. This is excellent surf for experienced surfers – definitely one to circle on the calendar.
There’s a lot of wind and chop in the afternoons, and a few days with onshore slop, so the early sessions are the key. The long-period swells we’re seeing will shape up best at the jetties here, giving longer, more powerful lines. The 8 September morning has a big 10ft ENE swell, but that’s too big for this break and really only for the extreme crew.
Overall, get on the morning sessions. The 31st of August and the 11th of September are your top picks.
