The Lowdown

Alright folks, Rusty here. Let's chew the fat on what's coming to our local break.

First off, the first few days are a real dud. The only spot we're looking at is Barrinha, and from Monday the 17th through to Thursday the 20th, it's flat and windy. Swells are tiny, under 3 feet, and the wind is blowing onshore and cross-onshore, making everything a choppy mess. Keep the boards in the rack.

Things perk up a little on Friday the 21st. The afternoon brings a 4ft SSW swell with clean, cross-off winds. It's a start. The real action fires up on Saturday the 22nd. The morning session is the one – a clean 5ft S swell (combined energy of 394) with light offshore breezes. That’s your first proper window. The afternoon gets messy with onshore winds, so make it an early start.

Now, Sunday the 23rd is where it gets proper exciting. The morning is a dead-set beauty: 6ft of S swell, and the wind is completely calm – glassy as a mirror. The swell period is a solid 11 seconds, giving it that real groundswell push and clean shape. This is the standout session of the whole run. The wave energy is solid (714), and the spot catches it well. It’s going to be a blast for intermediates and up. The water temp is sitting at 65°F, which is average for this time of year, so nothing unusual there.

Monday the 24th keeps the goods coming with a chunky 7ft S swell (energy hitting 1212) and clean offshore winds in the morning. That’s getting big and powerful, into the experienced surfer range. The afternoon swell bumps up to 8ft (energy 2880) but the wind swings cross-shore. The period is still a meaty 11 seconds, so it's all groundswell muscle.

The wind turns ugly for a few days after that, cross-onshore and onshore, chopping up the swell. Things go quiet from Wednesday the 26th through to Thursday the 28th. Friday the 28th afternoon has a tiny 2ft S swell with a 12-second period and clean cross-off winds, but it's small.

Then, for the long-range crew, Monday the 31st of August looks like a serious one. The morning is glassy again, with a 6ft SSE swell (energy 1515) and a super long period of 14 seconds. That's premium groundswell – fast, lined up, and best for the points and reefs. The afternoon pushes to 8ft S swell (energy 1862) with clean offshore winds. That's a big-wave alert for the experts only. It's a standout, but it's a long way off, so don't book the time off just yet.

The Bottom Line: Sunday the 23rd morning is your pick of the week for clean, fun, mid-sized waves at Barrinha. Monday the 24th morning is the big, offshore power session. And if the long-range models are on the money, Monday the 31st of August could be an absolute cracker for the experienced crowd. The rest is pretty quiet.

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.
