The Lowdown
Alright, folks, Rusty here. Let’s break down what’s coming for the next stretch. It’s a real mixed bag, but there’s a couple of windows that are gonna be worth your time.
The first chance to get a wave is on Saturday, August 22nd, at Barrinha. The swell is a solid 8ft from the south, but the wind is a cross-off from the SW at 12 mph, and it’s just not clean enough to make it good. The energy is there (963), but it’s a bit of a fight. The water temp is about normal for this time of year.
Sunday, August 23rd, the wind drops to a light breeze, 6 mph from the SSW, and the swell holds at 7ft from the south. The energy picks up to 1022, and it’s clean. It’s a solid session, but the real magic is coming.
Now, Monday, August 24th – this is the one. The morning is totally glassy, with a 3 mph SW wind, and the swell jumps to 10ft from the south with a very long period of 15 seconds. The energy is pumping at 3582. This is a big, powerful groundswell. For a spot like this, that long period will make the waves groom themselves, but it’s going to be a serious challenge. At 10ft, this is expert territory only. Beginners, stay on the sand. If you’ve got the skill, you’re in for a treat. Expect the lineup to be popular.
The rest of the week into early September is a bit of a washout. The wind turns onshore and stays strong, the swell drops, and the energy fades. Tuesday, August 25th, the wind is already onshore, and the swell is messy. The whole stretch from Tuesday afternoon through the end of the month is mostly poor, with choppy, lumpy conditions.
We get a flicker of hope on Wednesday, September 2nd, in the afternoon. The swell bumps back up to 7ft from the SSW, and the wind is cross-off from the SSW at 9 mph, giving clean conditions and energy of 1298. It’s a fun option.
Then, Thursday, September 3rd morning – this is the second true standout. The wind goes fully offshore from the west at 6 mph, the swell is 8ft from the south with a period of 13 seconds, and the energy is 1827. That’s a clean, powerful swell for experienced surfers. The conditions are excellent. Circle this one.
After that, the wind swings back onshore and the energy drops off. So, the best calls are Monday, August 24th (for experts only) and Thursday, September 3rd morning. The rest of the time, you’re either fighting the wind or waiting for a pulse.
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.
