The Lowdown
Alright folks, Rusty here, with a look at what's coming up at our local spot.
It's a bit of a slow start, but we've got a decent run of cleaner conditions later on. The first few days are a mixed bag, but the standout window is kicking off on the 9th of August.
For the first week, you're mostly looking at small, ordinary waves at Barrinha. Tuesday afternoon, the 28th of July, is the first real chance with a glassy 2ft south swell, but the rain might put you off. The combined energy is weak (134). Water temp is sitting around 66°, which is bang on average for this time of year – nothing special there.
Wednesday the 29th through to the next week is a write-off. The wind is onshore, the swell is small and messy, and the scores are low. We get a few clean moments on the 30th and 2nd of August, but the swell is just too tiny to get excited about.
Then things start to change. The real action starts on the morning of Sunday, the 9th of August. We've got a clean 4ft south swell with a solid 13-second period and light offshore wind from the southwest. The energy is pumping at 583, and it's set to be some of the best surf we've seen in the forecast. This is a genuine standout for the period.
The good times roll into Monday morning, the 10th of August. Another clean 4ft south swell, this time with a 12-second period and glassy offshore winds from the west-southwest (481 energy). The conditions will be pure.
And then we have a very special window on Tuesday morning, the 11th of August. It's a 6ft south-southeast swell. That's getting into the expert-only zone, but the wind is calm, making it glassy. The period is a short 8 seconds, so it won't have the grunt of a groundswell, but the pure energy (637) and total lack of wind will make for some fun, punchy beach breaks. A proper morning for the experienced crew.
The afternoons after those standouts get chopped up by onshore winds, and the contestable conditions continue into the 12th. So, mark your calendar for that Sunday-to-Tuesday window in early August. It’s the best we’ve got.
Rusty out.

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.
