The Lowdown
Alright, Rusty here, let’s talk about what’s coming up for Barrinha.
The outlook’s a mixed bag for the next two weeks. We’ve got a bit of a slow start, but there’s some real promise building. The water temperature is sitting at 64°, which is a touch cooler than usual for this time of year, but nothing too wild.
The first real chance to get wet looks like Wednesday morning, September 9th. The swell is a modest 4ft from the south, with a period of 10 seconds, and the wind is dead glassy. That’s a clean window, but it’s a small one. The combined energy is moderate at 376. It’s not a standout, but a good little session for the intermediate crew if you can get out before the afternoon cross-onshore kicks in.
The first real standout of the period is Saturday, September 12th. The morning has a 8ft south swell with a 10-second period, and it’s clean with a cross-off wind. The energy is strong, hitting 1401. The afternoon is where it gets serious, though. A 10ft south swell rolls in with an 11-second period, and the combined energy jumps to 4046. That’s a lot of power. The wind is cross-off and clean. This is a big, powerful swell, and at over 8ft, it’s for experts only. That’s the best on offer for the entire forecast.
Sunday morning, September 13th, is also a good call. The swell drops to a more manageable 6ft from the SSE, with a 9-second period. The wind is light and cross-off, keeping it clean. Combined energy is a solid 558. It’s a good follow-up session after Saturday’s big one.
There’s a gap after that, with a lot of poor conditions and onshore winds. The next real highlight is Tuesday morning, September 15th. The swell is 8ft from the east, with an 8-second period, but the wind is offshore and clean. The energy is strong at 1321. That’s a solid, clean wave, and the offshore wind will make it good for the more experienced surfers.
Wednesday morning, September 16th, is worth a mention. A 4ft south swell with a 9-second period, light offshore wind, and a combined energy of 388. It’s clean and small, a good one for the intermediates looking for a relaxed session.
The rest of the second week fades out quickly. By Saturday, September 19th and into the next week, the swell drops off and the winds are messy. The period from the 20th onward is mostly flat or tiny, with poor conditions. The 21st and 22nd have some surfable but very ordinary waves, nothing to get excited about.
For the pick of the fortnight, it’s hands down Saturday, September 12th. The afternoon session is the big one. That 10ft south swell with clean cross-off winds is a proper day for the experienced crew. Get on it.
Rusty.

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.
