The Lowdown

G'day, Rusty here. We’ve got a bit of a mixed bag on our hands for the next couple of weeks at Molhes de Mampituba. The early days are looking pretty average, with the best windows of clean surf tucked away in the second week, and a real standout that’s worth marking on your calendar.

Right now, the first real chance to wet a line kicks off on Wednesday morning, the 2nd of September. We’re looking at a 6ft SE swell with a period of 10 seconds. It’s not huge, but the wind is light from the SW early, giving us cross conditions. The combined swell energy is moderate (547). The water temp is sitting at 63°, which is about average for this time of year.

Thursday the 3rd is where it gets interesting. Early morning you’ve got glassy conditions with a 4ft ESE groundswell, period of 11 seconds. That’s clean and lined up, though the combined energy is moderate (429). This is a good window for an intermediate surfer to get some fun ones. The afternoon gets a bit onshore, so hit it early.

Friday the 4th and Saturday the 5th are pretty poor. Swell drops right off to under 3ft, winds are messy, and it’s mostly choppy. Not worth the paddle.

Sunday the 6th sees a bump in size with a 6ft SSW swell, but the period is short at 7 seconds and it’s blowing 15-19 mph cross-shore. That’s a lumpy, cross-chop mess. Combined energy is moderate (571), but the quality is poor.

Now, the first true standout comes on Wednesday the 9th of September. Early morning, you’ve got a 3ft SSE groundswell with a very long period of 12 seconds, combined energy of 553 (moderate). Wind is light and cross-off from the north. That’s clean, clean, clean. This is a low-tide friendly, small-wave gem for the river/jetties setup. Crowds are often here, so expect some company, but the conditions will be worth it.

Then we have a real monster on the horizon. Thursday the 10th of September, the afternoon session sees a 10ft ENE swell, combined energy of 2379 (very strong). The wind is cross-off from the NNE, making it clean. However, this is only for experts. At over 8ft, it’s way too big for beginners. The swell direction matches the optimum SE direction, but the size and power will be intense. This is the big one of the forecast, but you need to be solid.

Friday the 11th of September morning settles back to a more manageable 6ft E swell with a 10-second period, cross-off winds from the NNE, and clean conditions. Combined energy is 676 (moderate). This is another solid window.

Saturday the 12th of September morning offers glassy conditions with a 4ft E groundswell, period of 11 seconds, combined energy of 445. Very clean, but the swell is small. It’ll be a fun morning for a log or a fish.

Sunday the 13th of September morning has a 3ft E swell with a 9-second period, light cross-off winds, and clean conditions. Combined energy is 412. A small, clean session.

The rest of the second week sees a mix of marginal conditions and onshore winds. By Monday the 14th of September afternoon, we get another pulse of 7ft ESE swell, but it’s onshore and short-period. The week after that fades out with small, choppy surf. The standout remains Thursday the 10th for experts, and Wednesday the 9th for a clean, smaller session.

Stay safe out there, and keep an eye on the sky.
