The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Barrinha.
Right now, the first few days are a bit of a write-off. We’re looking at a weak, inconsistent swell and the wind is mostly cross-on or onshore, leaving the water a mess. Monday the 3rd and Tuesday the 4th are a no-go with tiny waves and poor conditions. The combined energy is barely registering (22 to 60). Wednesday the 5th and Thursday the 6th are flat and choppy. Friday the 7th actually cleans up a bit with a light cross-offshore wind, but there’s just no size to speak of – only 1ft to 1ft. You’ll be waiting a while.
The real action starts to build around Saturday the 8th. The swell kicks up to 5ft by morning and jumps to 6ft by the afternoon, with a long 14-second period from the south. The combined energy jumps to 1191 (strong), but the wind is still cross-on, so the surf will be a bit lumpy. It's a tease of what’s to come.
Now, here’s where it gets interesting. Sunday the 9th sees a solid 6ft south swell (combined energy 906, moderate to strong) with a clean cross-offshore wind from the SSW. The waves will be clean, but the period is a bit shorter at 11 seconds. Still, a good day.
But the standout for me is Monday the 10th of August. The morning brings a 8ft south swell (period 8 seconds) with a clean cross-offshore breeze, and the combined energy is a solid 761 (moderate to strong). That’s going to be a fun, clean wave for intermediate to advanced surfers. The afternoon gets bigger – 10ft from the south (period 10 seconds) – but that’s pushing into expert-only territory, and the wind turns light cross-on. Still, the morning session is the one to circle.
Then we get a couple of proper gems. Tuesday the 11th is a cracker: 8ft from the SSW, with a clean offshore wind from the SW at 16 mph. The combined energy is massive at 2471 (very strong). This is a wave for experienced surfers only – it’s going to be powerful and clean. The same goes for Wednesday the 12th: 8ft from the SSW, offshore wind again, combined energy 1693 (very strong). Two days of pure, pumping, offshore surf. The water temperature is running about a touch warmer than normal for this time of year at 68°.
After that, the swell drops but stays rideable. Thursday the 13th has a clean 5ft from the SSE with a light offshore breeze, but the period is short (11 seconds). Friday the 14th sees a bigger 7ft SSE swell (period 14 seconds, very long) but the wind is cross-on, so it’ll be a bit bumpy. Saturday the 15th turns into a messy, wind-affected 7ft from the east with a short period – that’s a kite surf day, not a paddle one. The last few days of the outlook (Sunday the 16th to Tuesday the 18th) fade back to small, weak, and choppy conditions.
So, the best of the best: Monday the 10th (morning) and Tuesday the 11th. Clean, powerful, and offshore. Perfect for the experienced crew. The swell direction is from the south and SSW, which is a good direction for this spot. Just be aware – crowds are sometimes an issue here, so get there early.
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.
