The Lowdown
Imperial Units
Alright folks, Rusty here. Let's get a feel for what Barrinha is serving up. It’s a bit of a slow burner, but we’ve got a couple of juicy windows.
First up, don't get keen too early. The opening days are a total mess with onshore winds and rain. Not worth a second look.
The first proper chance is on Sunday the 13th. Morning is where it’s at. We’ve got a clean 5ft swell out of the SSE, and a light offshore breeze from the SW is going to keep it glassy. The wave energy is moderate, and the 8-second period means it’ll be a bit jumbly but super fun for an intermediate on a log or a fish. That’s your best bet for the first week. Water temp is pretty standard for the season, nothing weird going on.
Things go a bit quiet again, but then we hit Tuesday the 22nd. This is the big one. We’re looking at a clean 6ft south swell with a 10-second period and a solid (525) energy reading. That’s got some proper punch. The wind is light offshore from the southwest in the morning, giving us clean, lined-up sets. Over 5ft, it’s going to be a bit much for beginners, but for the intermediates and above, this is the session to lock in. Quality waves with good shape.
Thursday the 24th afternoon also looks tidy with light cross-offshore winds and a 6ft south swell (293), giving another solid chance at clean waves. And the outlook wraps up on Saturday the 26th with a light offshore breeze and a 5ft south swell (469), so you've got options in that second week.
Bottom line: skip the first few days of junk, then keep your eyes on Sunday the 13th for a warm-up. The real standout is Tuesday the 22nd. That one’s got “best of the month” written all over 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.
