The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
First up, we’ve got a solid window of action coming through, but it takes a few days to really get going. The water temp is sitting at 64°F, which is a touch cooler than usual for this time of year – about 2°F below the norm, so nothing crazy, just a little fresh.
We kick things off on Tuesday the 8th of September, but honestly, don’t get too excited. Morning at Barrinha has a 5ft swell from the SSE with a 10-second period, but the wind is cross-on from the NNE at 6 mph, and the energy is moderate at 434. It’s a bit bumpy and marginal. The afternoon gets worse – wind picks up to 12 mph onshore, swell drops to 4ft, and the score is a zero. Best to wait.
Wednesday the 9th is where it gets interesting. Morning session is the standout of the entire outlook. The wind goes glassy – dead calm, 0 mph – and the swell is a clean 4ft from the S, 10-second period. The energy is moderate at 376, and the conditions are described as “good surf.” This is your window. The swell direction is SSE, which is about as good as it gets for this spot, and with glassy conditions, you’ll have clean, rippable waves. Crowds are possible here, so get in early.
Thursday the 10th is a bit of a letdown. Swell drops to 3ft in the morning, winds are cross-on again, and the energy is similar but the quality is poor. Not worth it.
Friday the 11th is a write-off. Swell is tiny, periods are short, and the wind is messy. Save your energy.
Saturday the 12th sees a big pulse of swell – 8ft in the morning, 8ft in the afternoon from the S, 10-second period. The energy jumps to strong – 1081 and 1194. This is solid, powerful surf. But here’s the thing: the wind is cross-off from the SW at 16 mph, keeping it clean, but at this size, it’s only for experienced surfers. Beginners, stay out of the water. The crowd potential is still there, but the power will thin the lineup.
Sunday the 13th is another good one. Morning brings 6ft of S swell, 9-second period, with offshore wind from the SW at 9 mph. That’s clean, offshore, shoulder-high waves. The energy is moderate at 494. This is a solid session for intermediates and above. Afternoon drops off a bit in size, but still clean.
Monday the 14th is a total mess – heavy rain, onshore wind, short-period swell from the E. Not surfable.
Tuesday the 15th morning is worth a look. Clean, light cross-off wind, 4ft S swell, 10-second period, energy at 274. Good conditions, smaller but fun.
Wednesday the 16th morning is another glassy slot – 5ft S swell, 7-second period, but the wind is light cross-off and the energy is moderate at 358. It’s clean, but the period is short so the waves will be a bit soft and crumbly. Still, a fun session.
Thursday the 17th morning is the last real standout. Offshore wind from the SW at 6 mph, 5ft S swell, 10-second period, energy at 558. Clean, punchy, and good shape. This is another one for the diary.
After that, it tails off. Friday the 18th is marginal, Saturday the 19th and Sunday the 20th are poor. Monday the 21st morning is poor, but the afternoon turns glassy with 6ft from the E, 9-second period, energy at 551. That’s a solid late-day option for the brave.
Tuesday the 22nd morning is glassy again – 5ft SSE swell, 8-second period, energy at 274. Clean, fun, but short period means it’s not world-class.
After that, the wind goes onshore and the swell drops, with the last few days of the outlook being poor. There’s a noticeable gap of poor conditions from the 23rd onward.
Best bets: Wednesday the 9th morning (glassy, clean, 4ft) and Sunday the 13th morning (offshore, 6ft). If you’re experienced, Saturday the 12th is a big-wave day.
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.
