The Lowdown
G’day, Rusty here. We’ve only got one spot to talk about for this stretch: Molhes de Mampituba. It’s a river/jetty break, fairly consistent, so you always have a chance.
The first few days are rough. Tuesday the 1st has rain, a strong cross-shore wind, and poor, messy surf. Not worth the effort. Your first real window is Wednesday morning, the 2nd. The swell hits 6ft from the ESE with a 9-second period (moderate energy at 455), and the wind goes dead glass. Clean, lined-up surf, and a great way into the run.
Thursday morning the 3rd is another glassy session, but smaller at 4ft. Then it drops away badly. From Friday the 4th through Monday the 7th, it’s cross-onshore garbage with weak energy and no shape. Pretty dead.
The turn comes Monday morning the 7th. The wind goes cross-offshore, the swell sets at a clean 5ft from the south (10 seconds, 482 combined energy), and the surface is clean. That’s a solid session. But the real standout is Tuesday morning the 8th. Cross-offshore breeze again, a 5ft SSE groundswell with an 11-second period (combined energy 526), and it’s glassy. The jetties will love that longer period—better shape, more push. Crowds happen often here, so plan around that.
The middle of the run dips again through the 9th and 10th. There’s a big spike on the 10th morning with an 8ft easterly swell, but it’s marginal with cross-offshore wind. That’s expert territory and a lucky break if you can get it clean.
Into the second week, things get heavy. Saturday the 12th morning has a 8ft south swell with an 11-second period—combined energy of 2514 (strong). The wind is light but cross-shore, and it’s only marginal. That’s a lot of water moving around a jetty, so only advanced guys should think about it. Sunday the 13th is bigger (8ft) but onshore and chopped out. The run fades into smaller, cleaner mornings around the 15th, but nothing tops that Tuesday the 8th.
So bottom line— Tuesday morning, the 8th of September, at Molhes de Mampituba. Clean glass, a good 5ft SSE groundswell, and the jetty will focus it nicely. Best of the run.
Stay salty,
Rusty
