The Lowdown
Alright, let’s talk about what’s cooking at Barrinha over the next couple of weeks.
We’ve got a solid run of clean south swell on the board, starting Sunday the 23rd, but the real standout is Monday the 24th. That morning you’ll see a clean 8ft south swell, period around 14 seconds, glassy conditions, and the water’s sitting at 67°, pretty average for this time of year. That’s the session to aim for. The wave energy is pumping with a combined energy reading of 3029, so it’s got some serious grunt. That’s going to be for experienced surfers only – it’s a bit too big for beginners.
Sunday the 23rd morning is still a good warm-up: 7ft south swell, cross-off wind from the SSW at 10 km/h, clean. The energy’s moderate at 1022. Afternoon gets a bit messier with cross-shore wind and a 8ft swell, but it’s not the best.
After Monday, the wind turns onshore from Tuesday morning, and the swell fades through the week. Tuesday the 25th morning has 7ft south swell but cross-on wind, and it just gets worse from there. By Wednesday the 26th, it’s a cross-on mess with 8ft swell, and by Friday the 28th, it’s tiny and choppy. The energy drops right off – we’re talking numbers like 232 and 68 by Friday afternoon.
There’s a big gap of poor conditions from Tuesday the 25th right through to the start of September. Nothing really worth paddling out for. The swell is small, the wind is mostly cross-on, and the energy is weak.
Then on Tuesday the 1st of September, a little south swell pops up around 4ft–4ft, with offshore wind in the morning, but it’s still ordinary. Wednesday the 2nd brings a jump – 12ft south swell, clean, but that’s way too big for Barrinha, so it’s a no-go. After that, it’s back to small, choppy junk for the rest of the forecast window.
So, if you’re after the best, get on it Monday the 24th morning. Otherwise, it’s a long wait for anything worthwhile.

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.
