The Lowdown
Alright folks, Rusty here. Let’s take a proper look at what’s cookin’ for the next couple of weeks at Barra do Sul.
To be honest, we’re in for a bit of a slow start. The first few days are pretty ordinary. Sunday the 30th and Monday the 31st are a write-off with poor surf conditions, cross-shore breezes, and weak, short-period swell. You’re better off staying home and waxing your board.
Tuesday the 1st of September is a tease. The morning goes glassy, and the swell bumps up just a hair to 4ft from the ESE, but it’s still weak—combined energy is only 162 (moderate energy). It’s surfable, but nothing to write home about. The afternoon stays glassy, though the swell drops a little.
Now, Wednesday the 2nd of September is where things get interesting. The morning is a standout. We’ve got a clean 7ft swell from the south, with a light cross-offshore wind. The combined energy hits 861 (moderate energy), and the description says "expect very good surf conditions." This is the best bet in the first week. Keep in mind, 7ft is a solid size—might be a bit much for beginners, but if you’re comfortable, this is the session to aim for. The swell direction is right on the money from the south, matching the break’s exposure.
After that, it gets a bit messy again. Thursday and Friday offer small, clean morning waves (2ft to 3ft) but nothing with much punch. The wind is good, but the energy is low.
The real standout, and the one you’ve got to circle on your calendar, is Monday the 14th of September. The forecast shows a big 12ft swell from the east, with a combined energy reading of 3880 (strong wave energy). That’s a powerful groundswell, and the period is 10 seconds. The issue? It’s predicted to be too big for this break. The file says it’s for experts only. If you’re a seasoned charger, this could be a day for the history books, but it’s a long way out—so keep an eye on it, but don’t bet the farm yet.
As for the water, it’s about average for this time of year, nothing unusual there.
The gap between the good stuff is real: from the 2nd to the 14th, there’s a lot of mediocre or poor conditions. But that Wednesday morning and that Monday in the second week are the ones to chase.
Stay stoked, and keep checking the forecast.
Rusty.
