The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ at Molhes de Mampituba.

Right off the bat, it’s a bit of a slow start. The first few days are pretty ordinary, with only small, weak swell and very ordinary conditions. The water temp is sitting at 64°, which is pretty much normal for this time of year, so no surprises there.

Tuesday the 28th has some tiny ESE swell around 2ft, and the morning is glassy with light W wind, so it’s clean but barely a ripple. That afternoon fades even more. Wednesday the 29th morning is similar, glassy again with a 2ft SSE swell, but the rain is heavy. The afternoon goes south quick with a cross-on S wind. Thursday the 30th morning is clean with a 3ft SSE swell, but it’s nothing to write home about.

We’ve got a real gap from Friday the 31st through to Sunday the 3rd of August where the swell is messy, short period, and the wind is cross or onshore, giving poor surf conditions. The energy is weak to moderate, so not much to work with.

Then things start to pick up. Monday the 4th of August morning looks like a sneaky little highlight: clean with a 3ft SSE groundswell (10-second period) and light W wind. That’s a nice, clean, glassy morning for a paddle if you’re keen.

Tuesday the 5th and Wednesday the 6th mornings also look clean with 4ft to 4ft SSE swell, NW and NNW winds, and moderate energy. These are good, clean windows.

The real standout though, and the one you’ll want to circle on the calendar, is Monday the 10th of August through to Wednesday the 12th. Monday afternoon has a glassy 3ft S swell with a long 12-second period, and the energy is strong. That’s clean, lined-up waves. Tuesday the 11th is the pick of the bunch: 5ft SSE swell, very long 14-second period, light NNW wind, and the energy is pumping. The water will be clean, the waves will have proper shape and power – this is for experienced surfers, as it’s a solid groundswell with a lot of push. Wednesday the 12th keeps that quality going with 5ft to 6ft SSE and S swell, long period, and light wind. The energy goes through the roof on Wednesday afternoon, which is serious power.

One thing to keep in mind: this is a river/jetties setup, and with that long period groundswell, the waves will be lining up nicely on the jetties. The crowd can be “often” here, so expect company on those standout days.

Overall, the first week is a grind, but the second week has some proper gold. The best of the best is Tuesday the 11th and Wednesday the 12th of August – clean, powerful, and well-shaped.

Rusty.
