Alright, Rusty here. Let’s have a look at what’s cookin’ at Barra do Sul.
We’re staring down a pretty quiet run to start with. Honestly, the first week is nothing to write home about – mostly small, weak slop and a lot of cross or onshore wind messing things up. The early mornings through Tuesday July 8th through to Thursday July 10th are all tiny, below 3ft, with barely enough energy to push you along – combined swell energy is only around 91-141 (weak). You’ll get a couple of clean windows with offshore or glassy conditions, but it’s really marginal – more of a longboard or a learner’s session if you’re desperate.
Now, the real glimmer comes later. Hold on for Saturday July 11th. The morning is where it’s at: clear skies, glassy as a mirror – wind is dead still, just a slight air from the NW. Swell is 4ft from the ESE with a 13-second period, giving it some proper push. Combined energy jumps to 483 (moderate). That’s a solid step up, and with that groundswell period, the waves will have shape and power. It’s a bit exposed to the swell, and it’s a beach setup, so the long period might make it close out in sections, but it’s the best on offer in the first week.
Sunday July 12th is worth a mention too – similar swell size, with a bit more energy in the afternoon (540), but the wind swings a bit more onshore. Still rideable.
The standout of the entire forecast is Sunday July 19th. That morning is a dream: calm wind, glassy conditions, and a nice 4ft E swell with a 12-second period. Combined energy hits 670 (moderate-strong), and with those conditions, it’s as clean as it gets around here. Expect clean, lined-up waves – a proper session for all levels. The afternoon gets a bit compromised as the wind picks up from the NNE, so make the most of that morning.
Before that, the week of July 13th to 18th is a mixed bag – some small clean windows on the 16th and 17th mornings (glassy, but only 3–3ft), and a nice run of glassy conditions Saturday the 18th with chest-high 4ft swell and 452 energy. Good, but not great.
Water temp is about average for the time of year, nothing weird going on. Crowds at Barra do Sul are sometimes an issue, but with the first week being so ordinary, you’ll have plenty of room. The standout on the 19th might draw a few heads, but it’s not gonna be packed.
All in all, the first week is a write-off unless you’re happy with thigh-high mush. The second week has some real promise, especially the 19th. Lock that one in.
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.
