The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer.
So, the overall picture for the next 16 days is a bit of a mixed bag, to be honest. There’s a little bit of small, clean swell hanging around for the first few days here at Barrinha, but after that, the wind turns ugly and the surf goes flat for a long stretch. We’re looking at a real gap in the action from around Friday, the 31st of July, all the way through to the middle of the following week. The good news is the water temp is sitting right at 66°, which is spot on for this time of year, so no surprises there.
Let’s start with the best of it. The highlight of the whole window is Monday morning, the 27th of July. We’ve got a clean 2ft swell out of the south, with a period of 12 seconds, giving us a nice bit of groundswell energy (219). The wind is glassy, absolutely dead calm from the NW, so the surface will be like a mirror. That’s a proper session for the intermediate surfer – small, clean, and fun. The crowds could be around at Barrinha, so get out early.
Tuesday morning, the 28th, is a write-off with a strong cross-on wind, but Tuesday afternoon brings a little window of hope. The wind goes glassy again from the SE, and the swell holds at 2ft from the south, period 12 seconds (123 energy). It’s surfable, but just ordinary.
Wednesday morning, the 29th, is another small, glassy morning with the same 2ft south swell (148 energy). It’s worth a paddle if you’re desperate, but it’s not going to blow your mind.
Then things get rough. From Friday, the 31st of July, the wind cranks up from the NNE, 12-15 mph, cross-on. The swell tries to bump up a bit, but it’s just choppy, messy, and no good. That nasty wind pattern sticks around, and the swell drops right off. By the 1st and 2nd of August, we’re down to 0.7ft to 1ft, and the energy is just a handful of numbers (8 to 38). That’s a full flat spell for a good week.
We do get a sniff of life again on Tuesday morning, the 4th of August. The wind goes glassy, dead calm, and we see a 2ft south swell with a 12-second period, giving us 105 energy. The surface will be clean, but the swell is small and the conditions are still just “very ordinary.” Still, it’s the best thing in that second week.
After that, the wind gets messy again, and the swell picks up a bit of size for the 6th, 7th, and 8th of August, but the wind is either cross-on or onshore, making it a chop fest. The biggest swell of the period hits on the 7th of August morning, with 4ft from the south, but it’s coming with a messy cross-on wind. That’s not a standout for surfing, just a bigger, blown-out mess.
So, the real standout is that Monday morning, the 27th of July. Get on it while it’s clean. The long gap from the 31st of July through to the 4th of August is a real bummer, but that’s how it goes sometimes.
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.
