The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for Molhes de Mampituba.

Right now, the ocean is a bit of a mess. We’ve got weak, short-period windswell from the ENE with a cross-shore breeze, and it’s just not doing anything for us. The water temp is sitting at 64°, which is pretty much what you’d expect for this time of year – nothing weird there.

We’ve got a few days of nothing really worth paddling out for, so hold your horses. Things start to get interesting on Saturday the 22nd. The swell bumps up to 7ft from the south, but the wind is messy and cross-shore, making it lumpy. The combined energy hits 1183 (moderate), but the quality is poor. It’s a pass for me.

The first real standout window opens on Sunday the 23rd. The morning is looking clean with a light cross-offshore breeze from the WSW. We’ve got a 6ft south swell, and the period jumps to 12 seconds – that’s proper groundswell energy. The combined energy is 905 (moderate). This is where it starts to get good. The waves will have shape and power, but it’s a beach-and-river setup, so that long period might make the waves a bit straight at times. Still, a solid session.

Monday the 24th is the absolute pick of the run. Early morning, the wind is glassy with a slight cross-off from the WSW. Swell is a clean 8ft from the SSE with a massive 15-second period. The combined energy is 2584 (strong). This is excellent surf, but it’s serious. At 8ft, this is expert territory – not for the faint of heart or beginners. The long period will make for powerful, grinding lines, best handled at the jetties. If you’ve got the skills, this is the day.

Tuesday the 25th is still fun with a 6ft SSE swell (13 seconds) and light offshore winds, keeping things clean. Combined energy sits at 943 (moderate). Good waves, but not the standout.

After that, things get a bit up and down. The wind starts to mess with the surface again mid-week, but Thursday the 27th morning offers a clean window with a dropping 4ft SSE swell and light offshore breezes. It’s smaller but clean.

Looking further ahead, Wednesday the 2nd of September morning shows promise with a 5ft south swell and 12-second period, combined energy of 812 (moderate), and clean offshore winds. Not a world-beater, but a decent option.

Then Thursday the 3rd of September morning is another one to circle. A 5ft south swell, 12-second period, and a glassy cross-offshore wind from the NNE. Combined energy is 825 (moderate). It’s clean and should have some fun lines. This is a long-range call, so less certain, but worth keeping an eye on.

Overall, the best on offer is Monday the 24th for the experienced crew, with Sunday the 23rd and Thursday the 3rd of September as solid backup sessions.

Rusty out.
