The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Alright, so the first bit of the forecast is a bit of a slow burn. The only real windows of clean surf kick off on Thursday, August 13th. The standout is without a doubt Barrinha. We’ve got a solid 7ft south swell rolling in with a 14-second period, which is a nice long groundswell, packing some serious energy (1576). The wind is a clean cross-offshore, so the faces will be looking good. This is intermediate territory, and with the combined energy being that strong, it’s not for the faint of heart, but for experienced surfers, it’s a real treat. The water temp is sitting around 66°, which is about average for this time of year, so no surprises there.
The Thursday afternoon high tide is also looking great, with a 7ft south swell and a 13-second period, wind still cross-off. It’s a solid two-session day.
After that, we hit a bit of a lull. Friday the 14th through to Sunday the 16th of August is messy, with onshore winds and choppy conditions. The swell drops right off, and the energy levels go from moderate to weak. There’s a bit of a size bump on the 20th and 21st, but the wind is cross-on or cross-off, and the conditions are no better than marginal. It’s just not worth paddling out for.
The next real blip on the radar is Monday, August 24th. The morning glass-off with a 5ft south swell (14s period, 897 energy) looks promising, and the afternoon is the same – glassy, 5ft south swell. It’s a solid, clean session, but it’s a one-day wonder with messy winds returning on the 25th.
Then, to round it out, we get another crack on Wednesday, August 26th. The morning is glassy with a 5ft south swell (14s period, 1247 energy). That’s a decent, clean wave again. The afternoon is a bit more iffy with a light cross-onshore breeze.
So, the real standouts are Thursday, August 13th, and the mornings of Monday, August 24th and Wednesday, August 26th. If you can only get out once, make it Thursday the 13th – that’s the pick of the bunch.
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.
