The Lowdown

Alright, folks, Rusty here. Let's be straight with you. The next two weeks are gonna test your patience. We've got a long stretch of nothing special, a real case of the doldrums, before things finally wake up. So don't go getting your hopes up for the next week or so.

The good news is that there is something to wait for. It’s gonna be a while, but things are looking up further down the line.

Right now, and for the next several days, we've got a lot of cross-onshore wind messing everything up. The swell is there, but it’s going to be a washing machine out there for the most part. Wednesday the 26th and Thursday the 27th have some size, around 8ft and 6ft, but with a period of 14 seconds and that cross-shore wind, it's gonna be lumpy and pretty much a write-off. The energy is strong, with the combined swell energy at 2167 and 979, but it's all over the place. Don't bother. From Friday the 28th through Monday the 31st, we're looking at a serious drop in size. We're talking ankle to waist-high junk, not worth your time. It's a proper lull.

After that dry spell, there’s a little pulse of energy that comes through on Tuesday the 1st of September and Wednesday the 2nd. Barrinha (Ria de Aveiro) is the only spot with a recommendation, and this looks like the window. On the Tuesday morning, the swell jumps to 8ft from the SSW with a period of 8 seconds, making for a cross-off breeze and clean conditions. It’s a bit on the short period side, and the energy is moderate (731), but it's clean. The standout is Wednesday morning, September 2nd. The swell is a solid 7ft from the SSE, with a period of 10 seconds, and the combined swell energy is a strong 897, with a light cross-off wind and glassy conditions. That's your best bet. This is about 6ft on the Thursday morning, but the afternoon turns to garbage as the wind swings onshore.

After that little burst, it looks like things fade out again. The weekend of the 5th and 6th is small again. Then towards the end of the window, around the 9th and 10th, we see another bump in size, ramping to 8ft, but the conditions are looking marginal with cross-onshore winds and onshore winds. There's a lot of energy there (1792 on the 10th), but it’ll likely be too messy to be any good for surfing. For a beach break like Barrinha, this kind of energy with that wind will be more of a kite-surfing setup than a paddle-surfing one.

So, to repeat: The standout is Wednesday morning, the 2nd of September. Get on it if you can. The long-range stuff for the 9th and 10th is promising but way less certain, so don’t bank on it just yet.

Stay patient.

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.
