The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the stretch ahead.

We’re kicking things off at Barrinha. It’s a fairly exposed spot, and the water temp is sitting pretty average for this time of year, so no surprises there. The first few days are grim, I won’t lie. Tuesday and Wednesday are a write-off with tiny, weak swell and dodgy winds. Thursday and Friday are even worse – barely a ripple and messy conditions. Don’t even bother paddling out.

The first real glimmer of hope comes in on Saturday, August 8th. The swell jumps up to 6ft from the S, with a solid 14-second period. That’s some proper groundswell energy rolling in (combined energy of 1434). The wind is cross-on, so it’ll be a bit choppy, but there’s enough push to get into something. This is more for the crew who don’t mind a bit of texture.

Sunday is a bit of a letdown after that, with the swell dropping and the wind staying messy.

Now, the standout. Monday, August 10th is the real deal. We’ve got a clean 5ft to 6ft S swell, period holding at 12 seconds, and the wind is light and cross-offshore. That’s about as clean as it gets around here. The combined energy is sitting at 705 to 778 – moderate, but with that direction and wind, the waves will have shape and hold their lines. This is your best session of the window. It’s not huge, but it’s quality. Crowds are something to keep in mind – Barrinha can get busy, so get there early.

Tuesday the 11th still has some clean morning waves, but the swell is dropping back to 4ft. Still worth a look if you missed Monday.

We then hit a dry spell from Wednesday the 12th through to Thursday the 13th. Onshore winds and rain make a mess of things. Don’t even think about it.

Friday, August 14th brings another solid pulse. Morning looks best with a 5ft S swell, 13-second period, and light cross-offshore winds. Combined energy is 982 – strong, punchy waves. The afternoon gets a bit messier as the wind swings, but the morning is gold.

Saturday the 15th is a bit of a gamble. The swell is still 6ft, but it’s coming from the E with a short, weak 8-second period. The combined energy is high (1035), but that short period and cross-on wind will make it bouncy and hard to ride. If you’re a beginner, this is too much and too ugly.

The final few days from Sunday the 16th to Tuesday the 19th are a mixed bag. Sunday morning has a tiny clean 2ft wave, but it’s weak. Monday has a 5ft S swell with clean offshore wind in the morning – that’s a decent option if you’re desperate, but it’s not the same quality as the 10th or 14th. By Tuesday, the wind is howling onshore and the swell is short-period junk. Best to hang up the board.

So, to sum it up: Monday, August 10th is the absolute best on offer, followed closely by Friday, August 14th morning. Don’t sleep on them.

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.
