The Lowdown
Alright, Rusty here. Let’s get straight into it.
Right off the bat, the outlook for Barrinha is a bit of a mixed bag. For the next several days, we’ve got some small, lumpy, cross-onshore slop that really isn’t worth your time. The water temp is sitting at 64°, which is about 1° cooler than normal for this time of year – nothing crazy, just a touch on the fresh side. The first real glimmer of hope doesn’t show up until Tuesday, the 1st of September.
Tuesday, September 1st afternoon is where things start to get interesting, but with a serious caveat. We’ve got a big 10ft swell rolling in from the SSW, with a short period of 9 seconds. The wind is a clean cross-off at 19 mph, which is good, but that swell is way too big for this spot. The combined energy is a massive 1497 (strong to very strong), and it’s predicted to be too big for the break. This one is for the absolute experts only, and honestly, it’s probably more of a spectacle than a session.
The standout of the entire run is Wednesday, September 2nd morning. This is your window. The swell drops to a still-powerful 8ft from the south, with a 11-second period, giving it some proper groundswell push. The wind goes glassy – zero wind, dead calm. The combined energy is still high at 1354, but this is that rare moment where a big, clean, and powerful swell lines up with perfect conditions. This is excellent for experienced surfers. The 8ft size means it’s a step up, so definitely leave the longboard at home.
After that, the quality drops off. Thursday, September 3rd morning offers a cleaner 6ft S swell with cross-off winds, making for a decent, if not spectacular, session. The combined energy is a moderate 627. It’s surfable but not a standout.
The second week is quiet. From the 4th through the 8th, it’s mostly small, messy, and cross-onshore, with barely a ripple of energy. There’s a bit of a pulse on Wednesday, September 9th – a clean 7ft SSW swell in the morning, with light cross-off winds and moderate combined energy (521) – good for a paddle but nothing that’ll get the heart racing. The rest of the 10th and 11th sees some larger swells but with poor wind or marginal conditions.
Best bet? Don’t waste your time on the small stuff. Wait for the glassy morning of Wednesday, September 2nd. That’s the one. For the rest, it’s a waiting game.
Rusty.

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.
