The Lowdown
Alright, this is Rusty. Let’s talk about what we’ve got coming up. It’s going to be a quiet start, but there’s some real potential later on if you’re willing to wait.
Right now, we’re looking at a long stretch of very small, weak surf. For several days, it’s going to be flat to tiny with poor quality. Don’t bother paddling out until at least Tuesday the 21st.
Around Tuesday afternoon, we finally see a little life. A 2 ft southerly swell trickles in, and the wind goes glassy. It’s surfable but ordinary – nothing to get excited about.
Wednesday the 22nd brings a slight bump with a 3 ft southerly swell and glassy conditions in the afternoon, but wave energy is weak at 141. Still not worth rushing for.
Finally, things turn on Thursday the 23rd morning. Barrinha will see clean 5 ft swell from the SSE under offshore wind. The combined energy is ramping up to a solid 322. This is where the window opens. The swell is still manageable for most, but just a heads-up: once it pushes to 6 ft that afternoon, it’s getting more serious. Thursday morning is your standout – clean, punchy, and good.
Friday the 24th keeps the momentum going with a 5 ft SE swell in the morning under light offshore wind. The afternoon goes glassy with 4 ft waves. This is good quality surf, consistent and inviting.
We get another solid pulse Saturday the 1st of August, 4 ft from the south, clean in the morning with light cross-off wind. Energy is 339 – that's moderate wave energy and the best on offer later in the forecast. It’s still a week and a half out, so keep an eye on it, but it’s promising.
Overall, the main standout days are Thursday the 23rd through Friday the 24th, with clean conditions and building swell. The later window around August 1st also looks good but has more uncertainty. Don’t expect much before that unless you’re just desperate for a splash.
Stay patient, keep the board waxed, and check back in.

Information about the Barrinha Surf forecast
The above surf forecast table for Barrinha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barrinha can be found by selecting the local surf guide option on the grey menu. Our Barrinha surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Barrinha) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Barrinha 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.
Barrinha is 17 km (11 miles) from Imbituba. If you plan a holiday in Santa Catarina - Sul, look for hotels and other accommodation in Imbituba. Imbituba has rooms for a wide range of budgets as well as car hire and transport links.
