The Lowdown

Alright, let's get into it. The surf story for Barra do Sul over the next couple of weeks is a slow burn, but it builds to something pretty special. There's a real gap to start with, so don't bother waxing up just yet.

We're looking at a long stretch of mostly small, messy conditions from Wednesday the 5th right through to the end of the first week. The water is sitting at about 67°, which is a touch warmer than usual for this time of year, but that's about the only bright spot early on. The swell is tiny, around 2ft, and the energy is weak (88). It's surfable, but very ordinary. The wind is alright early Wednesday morning—light offshore from the west at 3 mph keeping things clean—and by the afternoon it goes glassy, but the waves just don't have any push.

The rest of that first week is a write-off. Thursday, Friday, and Saturday are all plagued by cross-shore and cross-onshore winds, mixed with poor surf quality. There's a brief pulse of longer period, more powerful swell on the weekend of the 8th and 9th, with energy jumping into the 100s and even 400s, but the wind is all wrong—cross-onshore from the southeast at 9 mph—making it choppy and ugly. Not worth your time.

The real story starts to unfold on Thursday the 13th. The morning offers a solid jump in size: 5ft of east-northeast swell, with a clean offshore wind from the west at 6 mph. The energy is strong (379), and the conditions are lined up for good surf. This is the first real standout of the outlook. It's a bit of a beast for the beginners, but anyone with a bit of experience will be stoked on this.

The forecast gets even better for the following week, though it's a little further out so keep an eye on it. Monday the 17th morning is absolutely glassy, with a calm wind and a clean 5ft swell from the east-northeast. Then Tuesday the 18th and Wednesday the 19th are looking like the best days on offer. We get a clean 5ft swell from the east, with moderate offshore winds from the west-southwest at 16 mph on Tuesday morning, and a gentle offshore from the west at 9 mph on Wednesday morning. The energy is strong (353-364), and the conditions are clean. The long period groundswell (9 seconds) still has good shape, and with the offshore winds, it's going to be clean and fun. This is the highlight of the whole period. The crowds are listed as "sometimes," so you might have some company, but it'll be worth it.

A quick note on the 15th: there's a pulse of very long period swell (16 seconds) from the southeast, but it's accompanied by cross-onshore winds, so it's a marginal call. It might be better suited for a point break or reef, but at Barra do Sul, the wind is a problem.

So, to wrap it up: the first week is a bust. The standout is Thursday the 13th, and the absolute peak looks to be Tuesday the 18th and Wednesday the 19th. Get those dates in your diary.
