The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for the coming weeks.
We’ve got a slow start, but don’t write it off just yet. The first real action worth paddling out for shows up on Monday morning, the 7th of September. Barrinha is the only game in town this period, and it’s a fairly consistent spot, so keep the faith.
Monday morning the 7th, Barrinha sees a solid 6ft south swell with a 10-second period. That’s intermediate friendly, not too big. The wind is light and cross-off from the southwest, keeping things clean. Combined wave energy is pumping at a moderate 551. Water temp sits at 66°, which is pretty much spot on for this time of year, nothing unusual there. This is the standout session early on.
Monday afternoon the 7th gets a bit messy with a light cross-on ESE breeze, so the morning window is the one to chase. Tuesday the 8th is a write-off with a strong north-east cross-on wind hitting 16 mph, turning things choppy. Not worth it.
Now, Wednesday the 9th is a real treat. Morning session at Barrinha is glassy, dead calm, with a 4ft south swell, 10-second period. Clean as a whistle, light crowd potential sometimes, so it might pay to be early. The energy is moderate at 315. For an intermediate, that’s pure fun.
Thursday the 10th is marginal with the swell dropping to 3ft and a light cross-on wind, though the period stretches to 12 seconds, giving it a bit of shape. Not a standout, but worth a look.
Then we hit a rough patch. From Friday the 11th right through to Sunday the 13th, the swell gets either tiny or too big. On Saturday afternoon the 12th, the swell jumps to a massive 12ft from the SSW, with the combined energy hitting a whopping 2264. That’s expert-only territory, and even then, it’s predicted to be too big for this break. The same goes for Sunday the 13th with 10ft swell. Unless you’re a charger with a big gun, sit this one out.
Monday the 14th is also a no-go with onshore wind and messy conditions. The poor run stretches almost a full week.
Things start looking up again on Tuesday morning the 15th. A clean 5ft swell from the SE with a 12-second period and light cross-off wind from the SW. The energy is moderate at 646. It’s a fun, clean wave that’s good for intermediates.
Wednesday the 16th is the next real standout. Morning session brings a 7ft S swell, 9-second period, light cross-off wind, and combined energy at a strong 1305. That’s powerful but not out of control. Expect clean, punchy waves. This is the best on offer in the second week.
Thursday the 17th morning stays clean with a 4ft S swell, but the period stretches to a very long 13 seconds. That’s a groundswell, so the waves will have shape but longer lulls between sets. Energy is still strong at 1080. Good for a relaxed session if you’re patient.
Friday the 18th sees a big 8ft S swell, 14-second period, but the cross-on wind from the north-northeast makes it choppy. That’s expert territory and the conditions won’t help. Not a recommendation.
From Saturday the 19th onward, the swell drops steadily. By Sunday the 20th afternoon, it’s back to 3ft and glassy again, but small. The last few days of the forecast are tiny and windy, so the window closes out.
So, to sum it up: your two standouts are Monday morning the 7th and Wednesday morning the 16th. Both offer clean, punchy surf at Barrinha with good energy and no major wind issues. Don’t sleep on Wednesday the 9th morning either if you want glassy, smaller waves. The middle of the period has a long gap of poor or oversized conditions, so plan around it.
Rusty out.

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.
