Molhes de Mampituba Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get stuck into this one. We’ve got a solid run of surf on the cards for Molhes de Mampituba, with a real standout session kicking things off.

It’s all about that Tuesday morning, the 25th of August. Early doors, it’s clean with a light breeze and a solid 5ft swell pushing in from the SSE at 12 seconds. The wave energy is right there in the moderate zone (680), and the conditions are saying “expect very good surf.” This is the pick of the first few days, no doubt. The water temp is about average for this time of year, nothing unusual there. Keep in mind, this is a river/jetty set-up, so it handles that long-period groundswell nicely. It’s a spot that’s fairly consistent, and with that offshore wind, it’ll be lining up clean. The crowd factor is “often,” so expect some company.

Later that same afternoon, the wind swings onshore and things get messy. Give it a miss.

Wednesday morning the 26th sees the swell picking up to 7ft from the SSE with a very long period of 14 seconds. The wave energy kicks right up (1759), and the text calls it “excellent for experienced surfers.” The wind is a light cross-off, so it’s clean. This is a big, powerful groundswell, and while it’s fantastic for skilled surfers on a point or jetty, it’s over 5ft, so beginners might find it a handful. Wednesday afternoon turns to junk as the wind chops it up.

Thursday the 27th is back to a cleaner, smaller scale in the morning. We get 5ft from the SSE at 13 seconds with a gentle cross-off breeze. Clean waves, good energy (966). It’s a step down from Wednesday but still a very good session. Thursday afternoon is a write-off.

Friday the 28th through Sunday the 30th drops in size and period, but we get some clean windows. Friday morning has 5ft at 9 seconds from the ENE, clean, and decent energy (478). The standout in this little run is Sunday morning the 30th. The swell is a smaller 4ft from the East at 9 seconds, but the wind is glassy. Absolutely dead calm. That’s a major positive for a clean, cruisy session. The energy is still moderate (301).

Monday the 31st gets a bit messy with a 6ft ENE swell and poor wind, so that’s a pass.

There’s a real lull from Tuesday the 1st of September until the following week.

The next time things get interesting is Sunday morning the 6th of September. We’ve got a solid 8ft pulse from the ENE at 8 seconds. That’s a short-period swell and is borderline too big for beginners, but the wave energy is very high (1318). The wind is a moderate cross-off, keeping it clean, but the text flags it as “marginal” due to that short period and potential tide issues. Over 8ft is expert territory anyway.

Finally, a week later on Tuesday the 8th of September, the swell is back to 5ft from the East at 10 seconds. The wind goes glassy again in the morning. It’s a clean, long-period swell with decent energy (451), but it’s a long way out, so consider that a promising hint rather than a nailed-on guarantee.

So overall, if you’re paddling out, aim for that Tuesday 25th morning for the best all-round bet, or the Wednesday 26th if you’ve got the skill for bigger, more powerful waves. The glassy Sunday the 30th is the one for a relaxed, fun session. After that, keep an eye on the distant Sunday the 6th and Tuesday the 8th.

Rusty.
