The Lowdown
Alright, let's get this straight. Only one break to talk about: Barrinha. No other options.
Right now, we’ve got a mixed run ahead. The first real standout is Thursday the 10th in the morning. You’ll find clean 3ft swell from the south, with a 12-second period. That’s a solid groundswell, and the wind is glassy out of the NNE at just 3 mph. Water temp is 62°, which is about 4° colder than normal for this time of year – that’s much colder than usual, so you’ll want a thick suit. Combined energy is 421 (moderate), so there’s some push. Best early call.
That afternoon, swell bumps to 4ft, but the wind goes cross-on from the ESE. Not terrible, but not as clean.
Friday the 11th is a write-off – rain, cross-shore wind, and smaller surf.
Saturday the 12th brings a jump to 7ft from the south, but the period drops to 8 seconds – short-period, windswell. Cross-off wind from the SW at 12-16 mph keeps it clean-ish, but it’s marginal. Not ideal.
Sunday the 13th morning: 5ft from the SSE, still short period at 8 seconds. Cross-off wind from the SW at 9 mph keeps it clean. Energy’s 328 (moderate). Surfable, but nothing to write home about.
From Monday the 14th through midweek, it’s mostly onshore or cross-on, with poor conditions. Swell sticks around but quality tanks.
Now, for the long-range standout, keep an eye on Wednesday the 23rd morning. That’s over a week out, so don’t bank on it, but it’s promising. 6ft from the south at 12 seconds, with glassy winds from the ENE at just 3 mph. Combined energy is 928 (strong). That’s a proper groundswell with clean conditions – best combo of the whole run.
Thursday the 24th morning has a 16-second period, 3ft from the SSE, and energy at 957 (strong), but the wind is cross-on from the NE. That long period works best at a point or reef; at a beach break it might run straight.
Then we hit the 25th – Friday. Morning shows a massive 13ft from the east, cross-on at 12 mph with a 9-second period. Energy is 3009 (very strong). That’s way too big for most, and the wind is messy. Afternoon drops to 12ft, still huge, and the wind gentles up but stays cross-on. That’s expert-only, and even then, it looks more interesting for kite surfing than paddle surfing.
So, bottom line: Thursday the 10th morning is your best early call. Wednesday the 23rd morning is the long-range standout if you can wait. Most of the in-between is ordinary to poor. There are gaps of several days where it’s just not worth it, but the 23rd is worth marking on the calendar.

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.
