The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at our local spot.
Right off the bat, we’ve got some decent energy rolling in. The water temp is sittin’ at about 67°, which is pretty much what you’d expect for this time of year – no crazy anomalies, just normal. The overall pattern kicks off with a solid pulse of Southern Hemi groundswell, and the conditions are shaping up nicely for the first few days.
Sunday morning (23rd August) is a solid start. We’re lookin’ at a 7ft swell from the South with a 11-second period. The combined energy is moderate at 1022. Winds are light and cross-offshore from the SSW, keeping things clean. The break is a bit exposed, but with that light breeze, it’s gonna be lined up and fun. This is a solid intermediate wave – not too big, not too small.
Now, the real standout, the one you wanna circle on the calendar, is Monday morning (24th August). This is where it gets good. The swell jumps to 8ft from the South with a 14-second period – that’s a proper groundswell. The combined energy is strong at 3029. And get this – the wind is glassy from the SW, completely offshore. It’s gonna be clean as a whistle. For experienced surfers, this is the pick of the week. Just keep in mind, at 8ft it’s a bit too much for beginners.
Tuesday morning (25th August) still has some juice, with a 6ft South swell and glassy conditions from the NNE. It’s clean and workable, a nice follow-up to the Monday morning session. Afternoon turns a bit cross-on and choppy, so get your fix in early.
Then the wheels fall off for a while. From Wednesday (26th August) through to Saturday (29th August), the wind swings cross-on and picks up, the swell drops, and the quality goes right out the window. There’s a long stretch of poor conditions with onshore wind and lumpy, choppy waves. You’re better off stayin’ dry for most of that week.
There’s a small window on Thursday morning (3rd September) – a 6ft swell from the SSE with glassy conditions. The combined energy is moderate at 706, and it’ll be clean. It’s surfable, but not a standout by any means.
After that, the forecast gets a bit shaky again. The swell fades and the wind turns onshore for the first week of September. There are a few marginal sessions, but nothing to get excited about.
So to wrap it up – the best on offer is Monday morning (24th August) with that clean 8ft South groundswell and glassy offshore wind. Sunday morning (23rd August) is a solid runner-up. After that, it’s a long wait for anything decent.
Stay stoked, and keep an eye on the sky.

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.
