The Lowdown
Alright, this is Rusty comin' at ya with a look at the surf for the next couple of weeks.
We're starting off with a bit of a wait, folks. The first worthwhile session isn't until Monday the 31st of August, but it's a beauty to kick things off. We've got a solid pulse of East swell at Barrinha – 6ft of it, period around 8 seconds, which isn't super long but it's got some decent energy behind it (470). The wind is glassy from the NNE at only 3 mph. The water temp is about average for this time of year, so just grab the usual spring suit. That Monday morning is your standout for the first week – clean, fun, and good for an intermediate.
The rest of that first week gets real messy. By Tuesday the wind swings onshore and stays that way for days. The swell also backs off, dropping to that weak, low-energy stuff by Friday morning (64). There are some longer-period SE swells mid-week (11 seconds on Thursday) but the cross-onshore wind just kills it – choppy and poor.
We get a small window of clean, cross-off wind on Saturday the 5th, but the energy is just ordinary. That morning's 4ft from the S is surfable but nothing to write home about.
Now, hold onto your boards for Sunday the 6th of September. The swell really jacks up, hitting 12ft from the S with a massive 3769 combined energy. That’s a whole lot of ocean moving. But here’s the thing – that size is flat-out too big for this break. It's a washout unless you're a total charger, and even then, the period is a bit short for that size. Not the one.
The real gold is Monday the 7th of September. That's your big standout for the whole outlook. We get a proper groundswell – 7ft from the S, with a very long 13-second period, pushing 1475 energy. The wind is light from the SSW, keeping it clean and cross-off. That's a setup for some proper, powerful waves. It's an expert-only zone at that size, but for those guys, this one is on. The wind stays favorable into the afternoon, though the swell gets a touch bigger and the cross-shore wind chops it up a little.
After that magic Monday, it all goes to shit again. The wind swings back onshore from the 8th of September through at least the 10th, making a mess of the surf. The swell is there, but the conditions are just poor for surfing.
Things try to clean up around the 11th to the 13th. We get some cross-off winds, and the swell settles into the 6ft range from the E, with moderate 679 energy. On Saturday the 12th morning, with the light SSW wind, it actually looks like a clean and fun intermediate wave. That's your next real window after the Monday standouts. But by Sunday the 13th, the onshore wind returns.
The final call, Tuesday the 15th of September morning, has a tiny pulse of clean 4ft from the S. It’s just a whisper, but if you’re desperate, it might be worth a look.
So to sum it up: If you can get out Monday the 31st, you’re in for a treat. If you miss that, lock in Monday the 7th for some proper groundswell power. There's a decent gap around the 11th-12th if you're patient, but the real magic is those two Mornings.
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.
