The Lowdown
Alright, this is Rusty, and here’s the lowdown on Barra do Sul for the next couple weeks.
Right from the start, things are flat and poor. There’s nothing worth paddling out for until Tuesday the 8th. That’s a few days of waiting, but there are some clean windows coming up, so don’t lose hope.
The best bet in the first week is Wednesday morning, the 9th. The wind is clean and cross-offshore from the NW, with an east swell running about 4ft and an 8-second period. The combined wave energy is moderate at 207. This is your session for clean, fun waves without the chop. It’s a beginner-friendly break, and with those conditions, it’ll be a good morning out.
Looking into the second week, the real standout is Tuesday morning, the 15th. The wind is clean, cross-off from the SSW, and we’ve got a solid 4ft east-southeast swell with a 10-second period. The combined energy jumps way up to 513, the strongest we’ll see. That’s the session for some proper power and shape. It’s still a beginner spot, but the waves will have some grunt. Keep in mind this is over a week out, so it’s a promising look, not a guarantee.
Other than that, there are a lot of afternoons getting wrecked by cross-onshore wind, especially around the 13th and 14th. The water temp is about 68°, which is a touch warmer than normal for this time of year – nothing crazy, but comfortable enough.
So, bottom line: wait for the clean mornings. Wednesday the 9th is your early-week fun, and Tuesday the 15th is the one to mark down for some real energy. The rest is mostly for the patient.
Rusty.
