Barra do Sul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

First up, the water is sitting at 67°—that’s about 1° warmer than usual for this time of year, so nothing too wild, just a touch on the mild side.

Right now, there’s a bit of a gap at the start. The first real surf window kicks off Thursday morning, the 27th of August. We’ve got a small, clean SE groundswell rolling in at 3 ft, with a nice long period of 14 seconds. That’s proper groundswell energy, and with the wind going glassy from the NW, it’ll be clean. The energy is moderate (325). For a beginner spot like Barra do Sul, this is a decent little session. Expect it to be a bit inconsistent given the long period, but the quality is there. Crowds are sometimes an issue here, so you might have a few others around.

Friday morning, the 28th, is another standout. Swell bumps up a touch to 4 ft from the E, but the period drops to 8 seconds. Still, with glassy conditions from the NW again, it’ll be clean and fun. Energy is moderate (218). This is a good one for the early bird.

Saturday morning, the 29th, is also looking promising. Swell holds at 4 ft from the E, period still 8 seconds, but the wind is dead calm—glass. That’s a major positive. Energy is moderate (227). For a beginner-friendly break, this is about as good as it gets.

After that, the surf drops off a bit through the rest of the weekend and into the start of the week. There are some surfable but ordinary waves on Sunday and Monday mornings, with light winds and small swell around 3 ft, but nothing to write home about. The energy drops to around 150–183.

Then we hit a dry spell. From the 1st of September through to the 8th, it’s mostly poor conditions—cross-onshore winds, small swell, and low energy. There’s a brief window on the morning of the 4th with clean conditions and a tiny 2 ft E swell, but the period is a short 5 seconds and energy is weak (57). Not worth paddling out for.

We also get a bit of a pulse on the 5th with 4 ft from the ENE and 7-second period, but the wind is cross-shore from the SSE, making it choppy. Energy is moderate (211), but it’s marginal at best.

The real interesting one comes later. On Wednesday morning, the 9th of September—that’s over a week away—there’s a solid 7 ft ENE swell with a 7-second period. That’s moderate energy (696), but it’s coming in with a strong cross-onshore wind from the SSE at 12 mph. The wind is going to chop it up badly, so this is more of a kite-surfing setup than a clean paddle session. Not for beginners, and only for experts if they’re desperate.

The 10th of September morning offers a small reprieve with 3 ft from the SE and a 10-second period, glassy wind from the S. That’s surfable, but ordinary.

Overall, the best windows are the morning sessions on the 27th, 28th, and 29th of August. Thursday morning 27th and Friday morning 28th are the true standouts—clean, small, and fun for a beginner-friendly spot. After that, it’s mostly waiting for a better pattern.

Rusty out.
