The Lowdown
Alright, Rusty here again. Let’s cut to the chase on this one. This forecast is a slow burn, but if you can wait, there’s a cracker of a day later on.
First off, Tuesday the 18th and Wednesday the 19th? Forget it. The swell is flat and the wind is all wrong. It’s a waste of wax.
We start to see a little life on Friday the 21st, but nothing worth calling in sick for. Saturday the 22nd shows a pulse of energy with combined wave energy of 990, but the quality is dicey. It’s clean, but the swell is short and chunky.
Now, the one to circle on your calendar is Sunday the 23rd. This is our standout. The morning is glassy – dead calm winds. We've got a solid 6ft swell from the S, a 11-second period. The combined energy is a very respectable 714. This is a proper groundswell. Barrinha will be offering up clean, clean waves. Water temp is about average for this time of year. Get in early. The afternoon will pick up a light cross-shore, but it’s still going to be a great session.
Monday the 24th is a different story. The swell pumps up to 10ft from the S with a 13-second period. The combined energy is massive, over 2500. That’s a lot of ocean moving. But the word is it’s too big for Barrinha. It’s gonna be closing out or just a washing machine. This is a big-wave day for experts only.
After that, the surf drops off into the last days of August. The first week of September offers a very ordinary, weak 6ft SSW swell on Tuesday the 1st, but it’s short period and not worth getting excited about.
So, your play is Sunday the 23rd. Glassy, 6ft, clean conditions. That’s the best on offer.
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.
