Alright folks, Rusty here, taking a look at what Barra do Sul has cookin' for us over the next couple of weeks. Straight up, we're not talking about a total flat spell, but it's going to be a game of patience with some real standout moments if you time it right.

The opening stretch is quiet but promising. Saturday the 4th gets us going with a clean, glassy morning. We're looking at a small 3 ft swell ticking in from the SE with a period of 12 seconds – that's a nice, long-period groundswell for a spot like this. The water temp is doing its normal thing for this time of year, nothing weird going on there. The combined energy is moderate (259), and with glassy conditions, it's a solid, mellow start for the beginner-friendly waves here. The wind is super light, and the crowd is only a *sometimes* thing here, so you might have some space.

Saturday afternoon goes even smaller and glassier, but the energy drops off (163). Sunday the 5th is more of the same – small, glassy morning with that 3 ft SE groundswell (189 energy). Pretty ordinary but fun for a longboard or a foily. By Sunday afternoon the wind shifts cross-on and the quality goes south.

The real highlight, the one you want to circle on the calendar, lands on Saturday the 11th of July. The afternoon session is the pick of the whole outlook – glassy as a mirror, with the swell bumping up to 3 ft from the ESE and a 13-second period pushing through. The combined energy jumps to a solid 367, which is a proper, moderate punch for the area. That's a standout window for clean, lined-up waves.

Sunday the 12th morning keeps the good run going. Glassy again with a 3 ft ESE groundswell (265 energy). Another top-tier session before the wind messes with it later.

Then, look at Tuesday the 14th afternoon – a glassy window again, with a 4 ft swell from the SSE. That's the biggest wave height in the whole run, but the period is a short 8 seconds. It's a little wind-swell-ish, but with glass and moderate energy (349), it'll be punchy and fun for the folks who know the bank.

We've got a bit of a lull through the middle of the second week, but hold tight. Friday the 17th of July brings a really interesting, long-range promise. The afternoon shows a 4 ft swell from the SE with a *very* long period of 18 seconds. The combined energy hits a whopping 687, which is the strongest reading in the forecast. That kind of groundswell could produce some gorgeous, powerful lines, but it's a bit of a long way out, so stay loose. The wind is a light cross-shore, so there's a bit of texture, but that much energy is worth a look.

All in all, Barra do Sul has its moments. Don't sleep on the glassy windows around the 11th and 12th, and keep an eye on that big energy pulse on the 17th.

Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Barra do Sul may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
