The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got some solid energy on the way, but you’ll need a bit of patience and a good board choice. The first real chance to get wet is Monday morning, August 24th, at Barrinha. This is for experienced surfers only. We’re looking at a 8ft south swell with a long 14-second period, packing some serious punch – the combined wave energy is a massive 3029. That’s a lot of power. The wind is glassy, so the surface will be clean. This is a standout session for the crew who can handle it. The water is sitting at 66°, which is bang on average for this time of year, so no surprises there.
The rest of the week turns messy. By Monday afternoon, the wind shifts cross-shore, and the quality drops. Tuesday through to the end of August is a write-off. The wind is mostly cross-on and choppy, and the swell drops off a cliff. There’s a big gap of around 5 days where the surf is poor or non-existent. You’ll see a few knee-high lumps, but nothing worth paddling for.
The next sniff of something decent comes on Tuesday, September 1st. We’ve got a 8ft – 8ft south swell rolling in with a moderate 9-10 second period. The offshore wind is clean, making it rideable for those with a bit of experience. The energy is moderate (1150-1505). It’s not the quality of the 24th, but it’s the best of the second week. Expect a bit of crowd, as Barrinha can get busy in these conditions.
After that, the window closes again. A few small, clean days around the 4th and 8th of September, but the swell is barely 3ft and the wind is all over the place. Don’t get your hopes up for those.
The real standout is the Monday morning (August 24th) session. Big, clean, powerful. If you’re an expert, that’s your window. The Tuesday (September 1st) is a solid backup, but it’s not in the same league.
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.
