The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer at Barrinha over the next couple of weeks.
We’ve got a bit of a mixed bag coming up, but there are a couple of sessions that are really worth circling on the calendar. The water temp is bang on average for the time of year, so no surprises there.
The first real standout is Tuesday morning, 25 August. It’s all coming together nicely. We’re looking at a 6 ft swell from the south with a solid 12-second period, giving it plenty of push and shape. The wind is glassy out of the north at just 3 mph, so the surface will be clean as a whistle. The combined energy is strong (1100), so there’s plenty of power in the water. This is a very consistent spot, so you can expect waves to be rolling in regularly. Crowds are possible here, so get in early. That morning session is the best of the first week, no question.
The next one to keep an eye on is Wednesday morning, 2 September. We’ve got a 6 ft swell from the SSE, period at 10 seconds, and the wind is completely calm and glassy. The energy is moderate (589), and the conditions should be really good. This is a solid, clean option for intermediate surfers, but note that the swell is a touch over 5 ft, so it might be a bit much for beginners.
Then, the real highlight of the whole outlook is Friday morning, 4 September. This is one for the experienced crew. We’ve got a 8 ft swell from the south, period of 9 seconds, and a clean offshore wind from the WSW at 9 mph. The combined energy is very strong (1607), so there’s a lot of power behind these waves. Because it’s over 8 ft, this is for experts only. The wind is offshore and clean, so the faces will be smooth. This is the best session on offer, no doubt.
After that, Saturday morning, 5 September is still worth a paddle. A 5 ft south swell with a 10-second period, and a moderate offshore wind from the SW at 12 mph. The energy is moderate (450), and it’ll be a fun, clean session for intermediates.
The rest of the forecast is a bit of a write-off. From the 25th afternoon through to the 1st of September, the wind is mostly cross-on or onshore, and the wave quality drops off. There’s a huge gap of poor conditions from the 25th afternoon all the way through to the end of August. The 31st of August afternoon and the 1st of September offer a tiny bit of hope, but the wind is too strong for it to be any good.
From the 6th of September onwards, the swell fades away and the wind stays messy, so it’s not worth planning for.
So, to wrap it up: Tuesday morning, 25 August is your early call for clean, fun waves. Wednesday morning, 2 September is another good, clean option. But the absolute standout is Friday morning, 4 September – it’s a big, powerful, clean swell for the experts. Get on it.
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.
