The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for the only spot on the radar, Barrinha.

First things first, the water is sitting at 67°, which is about a degree and a half warmer than usual for this time of year. Not a crazy change, but you'll feel it's a little more comfortable than normal.

Alright, the outlook starts off quiet. Wednesday the 5th and Thursday the 6th are a write-off – tiny, weak surf with a combined energy of only 104 and 82, and the wind is either on it or just messy. Not worth paddling out for.

The first real chance comes Thursday afternoon the 6th, but it's only 2 ft and the wind goes straight onshore. Don't bother.

Friday the 7th sees a jump in size, but it's a messy one. The morning is tiny, but the afternoon brings a 6 ft southerly swell with a short period of 8 seconds. The wind is cross-off, which keeps it clean, but the quality is poor and the combined energy is moderate at 413. It's a bit of a washing machine.

Saturday the 8th is for the experts only. We've got a big 8 ft southerly groundswell arriving, with a period of 14 seconds. That's a lot of energy (2103) and it's coming from the south, which is *not* the optimum direction for Barrinha (SE). Plus, you've got a strong cross-onshore wind at 25 km/h. Honestly, this setup looks more interesting for kite surfing than paddle surfing. It's going to be a bumpy, choppy mess.

Sunday the 9th is a bit of a mixed bag. The morning is still 7 ft with a short period (8 seconds) and cross-off wind, scoring a marginal 2. The afternoon cleans up with a 7 ft swell, still short-period, but the wind is a gentle cross-off, making it clean. The combined energy drops to 645. It's surfable, but not the stand-out.

The real standout is Monday the 10th and Tuesday the 11th. This is where we get the best of the run. On Monday morning, we have a solid 7 ft southerly groundswell with a 13-second period. The wind is light and cross-off, the combined energy is pumping at 1248, and the conditions are described as "very good." This is the one to circle. It's a bit of a size for beginners, but for intermediates and up, it's game on. The quality holds through the afternoon with a 6 ft set.

Tuesday the 11th keeps the dream alive. The morning brings a 7 ft southerly swell at 12 seconds with a clean offshore wind (SW at 12 mph). The energy is 1320. This is going to be clean, powerful, and lined up. The afternoon is a little more marginal with a cross-off wind, but still a solid 7 ft.

After that, the surf stays good but the quality drops. Wednesday the 12th morning is the absolute peak for experienced surfers, with a 7 ft SSE swell at 12 seconds, light cross-off wind, and a perfect score of 4. The combined energy is 1415. This is the best of the best. It's a little too big for beginners, but for the crew that knows what they're doing, it's a 10 out of 10 morning. The wind swings onshore in the afternoon, so get it early.

The rest of the week is a fade. Thursday the 13th has a glassy afternoon with a 5 ft southerly swell, worth a look. Friday the 14th is a solid afternoon again with a 6 ft swell and clean conditions. Saturday the 15th gets blown out by an onshore easterly, and Sunday the 16th is a total write-off with strong cross-onshore winds and a choppy 8 ft easterly swell.

Monday the 18th is the last glimmer of hope. The morning brings a 7 ft easterly swell with a 10-second period and a light cross-off wind. The combined energy is 1004, and it's rated as "very good." A solid session to end the run.

So, to wrap it up: the best of the best is the Monday 10th morning, the Tuesday 11th morning, and the Wednesday 12th morning. Wednesday the 12th is the crown jewel for the experts. After that, it's a slow decline with a few decent windows until the 18th.

Rusty, signing off.

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.
