The Lowdown
Alright lads, Rusty here. Let’s break down the next couple of weeks.
We’re starting with a bit of swell on Sunday the 9th of August, but the wind is a bit off. The real goods show up on Monday the 10th and Tuesday the 11th.
The pick of the bunch is Barrinha on Monday morning, 10 August. You’ve got a solid 8ft south swell with a 12-second period – that’s real groundswell, lots of energy. Wind is offshore from the southwest, keeping things clean. The water temp is about 67°F, pretty average for the time of year. The combined energy is pumping (2685), so there’s some serious power. This one’s for the experienced crew; it’s over 7ft and that long period can make it a bit tricky at a beach break, but with offshore wind, it’ll be clean. It’s a fairly exposed spot, and it can get busy sometimes, so plan ahead.
Tuesday morning, 11 August is another cracker. Swell is a bit smaller at 7ft, still south with a 12-second period, but the wind goes glassy. Absolutely perfect conditions. The energy is a bit lower (1495), but still excellent for a good surfer. Crowds are a possibility, but glassy conditions make it worth the hassle.
The surf fades after that. Thursday morning, 13 August has a smaller 6ft swell with a very long 14-second period and light cross-off wind. It’ll be clean, but the energy is lower (1449).
The second week is a write-off. From the 16th of August, it’s mostly small, weak, and messy. There’s a spike of short-period swell on the 20th, but it’s 6ft with a 7-second period and cross-shore wind – just sloppy. From the 18th to the 24th, it’s a long stretch of tiny waves and poor quality. The 24th is flat.
So, your windows are Monday the 10th and Tuesday the 11th. Don’t sleep 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.
