The Lowdown
Alright, surfers, Rusty here. Let’s talk about the stretch ahead at Barrinha.
It’s a bit of a slow burn to start. For the first couple of days, we’re looking at pretty weak surf – just small, short-period leftovers. Not much to get excited about, honestly. You’d be fighting for a knee-high ripple with no power behind it.
The real story begins to unfold towards the end of the week, though. Friday afternoon sees a pulse of new energy, but it’s messy. The swell jumps up to 7ft, but the period is a short 8 seconds, and it’s crossed up with a strong S wind. It’s gonna be a jumbled mess, not worth your time. Saturday stays poor with even more size – over 7ft – but it’s onshore and choppy, so the quality is just not there.
Now, Sunday is where we start to see some promise. The wind goes cross-off, and while the energy is moderate (745 on the combined meter), it’s setting up for a cleaner afternoon. We get another push on Monday with a moderate 945 energy, but it's Tuesday and Wednesday that are the real standouts. Tuesday morning has 7ft of S swell with a 11-second period and clean offshore winds. The energy is cranking at 969, and it’s looking like the best session of the week. Tuesday afternoon gets even better, with the swell holding at 7ft, a 12-second period, and the energy jumping to 1424. This is the one – excellent conditions, and the water will be a warm 67°, which is about a degree and a half above average for this time of year. Wednesday morning continues the run with similar size and a clean cross-off breeze. But watch out – that water temp anomaly means it’s slightly warmer than usual, which is a nice little bonus.
We’ll get a bit of a lull from Thursday the 13th into the weekend, with a mix of onshore winds and building swell that gets too big and unruly. Saturday the 15th is huge – 10ft of swell with a 16-second period – but the wind is blowing onshore and the energy is just way too much for this spot. That’s a pass for anyone not looking for a washing machine.
After that, it fades out quickly. The last few days of the window are pretty flat, just small dribbles with poor conditions. Keep your eye on that Tuesday and Wednesday window – that’s your best bet by far.
Rusty out.

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.
