The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are shaping up like for our little corner of the coast.
It’s a slow start, to be honest. We’re looking at a pretty rough run of weather and weak, messy surf through the first few days. The water is sitting at 62°, which is a solid 4° colder than normal for this time of year – you’ll definitely feel that chill.
Friday the 11th is a write-off. We’ve got light rain and a cross-onshore breeze chopping up tiny 2ft swell from the south. The energy is weak, only about 151 (combined energy), and it’s just not worth paddling out for. That carries through Saturday the 12th too, though the wind swings offshore in the morning. The swell bumps up to 5ft by the afternoon, but it’s short-period stuff (6-8 seconds) and the wave quality is still poor.
Sunday the 13th is where we start to see a glimmer. The morning looks decent with a clean 4ft swell from the SE and light offshore winds. The energy picks up to 292 (moderate), and while it’s not pumping, it’s a solid *surfable* window after a few days of nothing.
Then we hit a bit of a lull. Monday and Tuesday are plagued by onshore winds and rain, though Tuesday the 15th has a glassy morning with a tiny 2ft swell – really only for the keenest longboarder.
Wednesday the 16th morning brings clean 3ft surf from the south, but it’s still small.
Now, here’s the standout: Thursday the 17th. This is the best on offer in the whole outlook. The morning is absolutely glassy – zero wind – with a solid 6ft south swell rolling in. The energy is strong at 865 (combined energy), and it’s a proper groundswell with an 11-second period. That’s going to produce some nice, well-shaped lines, especially if you’re surfing a spot that handles it. It’s a good size for intermediates, and the clean conditions will make it a special session. The afternoon gets tricky with a big 7ft SSE groundswell (14-second period) but cross-onshore winds chop it up, and the energy jumps to a massive 1726. That’s a lot of power, but the wind kills the quality. For experts only in the arvo, and even then, it’s messy.
After that peak, Friday the 18th and Saturday the 19th drop back down to small, weak surf with onshore breezes.
We get another interesting pulse late in the window. Tuesday the 22nd has a glassy morning with 5ft swell from the south, but it’s a short 7-second period, so it’ll be a bit fat and crumbly. Wednesday the 23rd is cleaner with a 5ft SSE swell and a better 10-second period, light offshore winds, and moderate energy (439). That’s another solid option for a morning session.
The very end of the run, around Friday the 25th and Saturday the 26th, fades back to small, weak, and onshore.
So, the real highlight is Thursday morning the 17th at Barrinha. Clean, glassy, 6ft south swell with good period. It’s the one to circle on the calendar. For the rest, it’s a patchy forecast with a few decent mornings but nothing else that really screams.
Stay stoked, catch you in the water.

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.
