The Lowdown

Right then, let’s have a look at what’s on offer for the next couple of weeks. It’s a bit of a mixed bag, but there are some proper gems to get excited about if you’re patient.

The opening days are ordinary, with a bit of small, short-period swell and moderate onshore winds. Sunday morning the 13th brings a bit of 4ft SSW swell, but it’s windy and cloudy – surfable but nothing to write home about. The real story starts to build from Monday the 14th. The morning sees a jump in quality: a solid 4ft S swell, period stretching out to 11 seconds, with gentle offshore wind. The combined energy is strong at 460, so you’ll feel the push. The water’s sitting at 62°, which is a fair bit colder than normal for this time of year, so suit up properly.

The standout is shaping up for Wednesday the 16th. The morning session at Barrinha is firing: 6ft of S swell, clean with a gentle offshore wind, and the combined energy is pumping at 916. That’s proper, solid surf – not for beginners, but intermediates will have a ball. It’s the pick of the first week, no doubt.

Thursday the 17th is tricky. The swell hangs around at 6ft from the S with an 11-second period, but the wind swings cross-onshore and then onshore, so it gets messy. Worth a look early if you’re keen, but it won’t be pristine.

There’s a long dry spell from the 18th through the 20th – small, weak, and choppy. The swell drops right off, with energy readings in the double digits. Not worth the paddle.

Then things turn on again. Monday the 21st has a nice pulse of 7ft E swell, glassy in the morning, with moderate energy (589). The glassy conditions are a huge plus – clean, lined-up waves. Tuesday the 22nd keeps the good run going with 6ft E swell, again glassy both morning and afternoon. This is consistent, quality stuff for the intermediate crew.

The second week gets a bit wild. Wednesday the 23rd is okay but wind picks up. The real belter is Thursday the 24th morning: 5ft S swell with a very long period of 14 seconds, glassy conditions, and combined energy of 981. That’s a groundswell with real punch – perfect for a point or reef break. It’s the top call of the whole outlook. After that, the wind turns onshore and the swell fades, with poor conditions through the 25th and 26th.

Sunday the 27th afternoon sees a return of 7ft S swell, but it’s messy. Then Monday the 28th morning brings a big 8ft S swell with a 14-second period – massive energy at 2076 – but the cross-onshore wind and rain showers mean it’s only for the experts. That’s a powerful, heavy day.

So, if you’re planning: Wednesday the 16th morning and Thursday the 24th morning are the absolute standouts. The 24th is the best of the lot – that long-period glassy swell will be a dream.

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.
