The Lowdown

Alright folks, Rusty here. Let’s dive into the local outlook for Barrinha.

We’re looking at a real mixed bag over the next 16 days, with a frustrating start, a couple of absolute monster days that are too big for most, and a few promising windows for the patient surfer. The first week is a write-off for quality waves, and we’ve got a big gap of poor conditions before things get interesting. Hang tight.

The water temp is sitting right around 66°F, which is dead average for this time of year, so no need to mess with the wetsuit thickness.

The first chance to get wet is on Sunday morning, the 30th of August. We’ve got a tiny little 4ft swell from the east with a period of 8 seconds, but the wind is glassy, dead calm. The combined energy is still weak at just 180, so the waves will be small and soft, but it’ll be clean. For a beginner, this is your best shot all week – it’s a no-stress session. The crowd situation is “sometimes” here, so you might have a few mates out, but nothing crazy.

Then we hit a dry spell. Monday and Tuesday are a no-go with onshore winds and chopped-up surf. The following Saturday, the 5th of September, is a tiny cleanup with 2ft from the SE and cross-off wind, but the energy is a mere 107 – it’s barely a ripple.

Now, the standout window. If you are an expert, you need to circle Wednesday, the 2nd of September. A massive 12ft swell from the south arrives with a 10-second period. The combined energy jumps to 4205, which is a proper pumping. The wind is a clean cross-off. But listen – at 12ft, this is not for the faint of heart. This is only for experienced surfers who know the break. The same goes for Sunday, the 6th, where we see an 12ft to 13ft south swell, with the energy hitting 5504. And then Monday, the 7th, the swell bumps to 13ft from the south with a very long period of 16 seconds, and energy is screaming at 6895. The wind is glassy that morning. That’s a world-class wave, but it’s a beast. For the average surfer, these days are a spectator sport.

A more manageable option appears on Saturday, the 12th of September. The swell is 6ft to 7ft from the east, with a short 8-second period. The wind goes glassy in the afternoon. The energy is a moderate 565. This is a good, fun-sized day for a confident intermediate. It’s the best chance for a solid, clean session without the raw power of the bigger swells.

So, to wrap it up: the best on offer for the general surfer is definitely the glassy morning of the 30th of August for the small-wave crew, or the calm afternoon of the 12th of September for a bit more size. For the experts only, the 2nd, 6th, and 7th of September are massive, with the 7th morning being the absolute standout for a big, clean, long-period groundswell from the south.

Stay safe out there. 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.
