The Lowdown
Alright, let's get into it. The next couple of weeks start off with a big old nothing. We're looking at a four-day gap before anything worth paddling out for shows up.
Your first real chance is Sunday the 9th. It's a bit rough in the morning with some rain and a cross-off breeze, but the afternoon cleans up. The swell jumps to 8ft from the south, with a 11-second period. It's got some grunt to it, but it's not perfect. The energy is moderate at 2290.
The real gold is from Monday the 10th through Wednesday the 12th. This is the standout run. The wind goes offshore and glassy, the surf is holding at 6ft to 7ft from the south with a nice 13-second period. The energy is strong, hitting the 1200-1300 range, and the conditions are simply very good. But Tuesday the 11th afternoon is the absolute winner – completely glassy, zero wind, and a solid 6ft of clean south swell. That’s the one to be in the water for.
Wednesday the 12th is still good, but the wind goes cross-on, so it’s not as pristine. It’s still got a solid 6ft of swell, but you’ll be dealing with some texture.
Thursday the 13th offers a clean glassy morning, with the swell easing to 5ft. It’s another good day. But then Friday the 14th and Saturday the 15th get messy with cross and onshore winds, and the quality drops off a cliff. There’s still swell, but it’s chopped up and not fun.
From Sunday the 16th through Tuesday the 19th is a write-off. The swell drops out, the winds are terrible, and the energy is weak, bottoming out in the low tens. It’s not worth the drive.
There’s a small flicker on Thursday the 20th with a glassy morning and a 4ft swell, but it’s not a game-changer.
The last decent look is Friday the 21st. The morning is clean again, with a 5ft south swell and light cross-off winds. It’s a good, clean wave, but it’s a one-off before it fades for the weekend.
So, if you want the best of it, get out there Tuesday the 11th. That’s the day. The whole stretch from Monday to Thursday is your best bet for quality, but that Tuesday afternoon is as good as it gets.
Stay stoked.

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.
