Barra do Sul Surf Forecast and Surf Report

G’day, Rusty here. Look, we’ve got a pretty mixed bag on the cards for Barra do Sul over the next couple of weeks. The start is pretty grim – we’re looking at a few days of poor, choppy conditions right through to the end of the first week. Not much to get excited about early on. There’s a bit of a gap before things start to clean up.

First up, Friday the 4th through to Monday the 7th of September, there’s nothing doing. It’s all cross-onshore or cross-shore breeze, small messy swell, and the combined energy’s weak to moderate (136 to 268). The water temp is about average for this time of year. Honestly, it’s a write-off for a paddle. The setup at this beach-and-reef break with that onshore wind and weak, short-period swell looks more interesting for kite surfing than surfboards.

Then on Tuesday the 8th of September morning, we finally get a window. The wind swings light WSW, going cross-offshore, and it’s clean. Swell is 2ft from the SE with a long 12-second period – proper groundswell. The combined energy is moderate (252). It’s still small, but it’ll be the best we’ve seen. A decent option for the beginner crew on a longboard. The spot is fairly consistent, and crowds are sometimes a thing, so you might have some company.

Wednesday the 9th morning is also clean with a light WNW cross-off breeze. Swell bumps to 5ft from the east, but period drops to 8 seconds. Combined energy is moderate (296). It’s rideable, but that shorter period means it’ll be a bit crumbly.

Thursday the 10th morning looks similar – clean again with a light NNW cross-off, 4ft east swell at 8 seconds. It’s ordinary but doable.

Here’s the standout: Friday the 11th of September morning. That’s your best bet. Glassy as it gets – light south wind, dead calm. Swell is 4ft from the east at 8 seconds, combined energy moderate (249). For a beach-and-reef setup, that glassy morning will make it smooth as butter. It won’t be pumping, but for clean, small waves, that’s the session to aim for.

After that, we get a bit of a run of ordinary again through the weekend and into the next week. There’s another spike in size on Monday the 14th of September afternoon – the swell hits 6ft from the east, 8-second period, and combined energy jumps to strong (599). Wind goes light WSW cross-off, so it’s clean. That’s a decent pulse, but at 6ft it’s getting a bit much for beginners. For the more experienced crew, that’s worth a look.

Tuesday the 15th morning holds a 5ft east swell with a light WSW offshore, clean again. Combined energy is strong (455). After that, the wind turns messy, and it fades into cross-shore chop and weaker energy through the rest of the week, right up to Saturday the 19th.

So to wrap it up: the best two windows are Friday 11th morning for glassy small waves, and Monday 14th afternoon and Tuesday 15th morning for a bit more size and clean conditions. The rest is either blown out or too small to bother. Get out there when it’s clean.

Rusty.
