The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s coming down the pipe for our stretch of coast. The long-range charts are showing a bit of a mixed bag, but there are a couple of moments that have me buzzing. We’ve got a run of small, clean days ahead, but the standout is definitely that pulse of energy early next week.
The first real window to get excited about opens up on Monday, the 10th of August. After a couple of days of junky, cross-onshore stuff with light rain on Saturday and Sunday, things finally swing around. Monday morning the wind is offshore and light, and we’re looking at a solid 7ft of south swell with a nice 14 second period. The energy readings are up there in the strong range (2487), and it’s shaping up to be the pick of the week. The water temp is sitting at 67°, which is about normal for this time of year.
For experienced surfers, this is the one to circle. Barrinha is going to be handling that size well. The breeze is light, so it should be pretty clean. It’s a very consistent break, so you won't be sitting around waiting, but you might have some company. Monday afternoon backs off a touch to 8ft but the wind goes a bit cross-off, still clean but not as perfect as the morning. Then Tuesday the 11th, we get a glassy morning with 7ft of south swell. It’s still good, but that Monday morning is the winner.
From there, things get a bit more complicated. The swell hangs around in the 5ft to 6ft range, but the wind swings back onshore from the NNE, putting a chop on the surface and making it feel less inviting. Thursday the 13th has a longer period swell, 15 seconds, but the cross-onshore breeze is going to mess with the shape at this beach. Friday the 14th cleans up a bit with a cross-off breeze and 6ft to 8ft of south swell, though it’s not going to have the same magic as Monday.
The following weekend and into the start of the next week is where it fades. Saturday the 15th drops off to 4ft to 4ft and gets rained on. Sunday the 16th is poor, with some short-period junk from the east. Then Monday the 17th, the swell collapses to 2ft and the wind is howling from the NNE at 19-22 mph. That’s a write-off; you’d be better off finding something else to do. We see a few tiny pulses of energy mid-week, but nothing that’s going to get your heart rate up. The 20th and 21st see a small bump of swell to around 4ft, but it's short-period stuff and the conditions are ordinary.
The long-range crystal ball is a bit murky for the final weekend. The 22nd and 23rd show some energy returning, with the 23rd looking a little more interesting. A morning offshore wind and a S swell of 5ft might give us a salvageable final day, but it’s a promise from a week out, so I wouldn’t book my schedule around it just yet.
So, there you have it. Monday the 10th is the one. Get on it. Otherwise, it’s a waiting game until the end of the window.
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.
