The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, we’ve got a long, flat spell. The first few days are pretty much a write-off – tiny waves, messy wind, just not worth paddling out for. We’re looking at a gap from now until the morning of Tuesday the 4th of August before anything even gets close to being surfable.
The first real chance to wet a line comes on Tuesday the 4th of August. The swell finally pops up to about 3ft, coming from the south with a period of 12 seconds. That’s a long-period groundswell, which means better-shaped waves but longer waits between sets. The combined wave energy sits at a moderate 291. The afternoon looks better – the wind swings around to a light breeze from the south, cleaning things up nicely. Expect good surf conditions. It’s not the biggest, but it’s a start.
Now, the standout. If you’re an experienced surfer, circle Monday the 10th of August on your calendar. The morning brings a solid 8ft swell from the SSE, with a long 14-second period. The combined energy is a hefty 2376 – strong, powerful stuff. The wind is light and offshore from the SW, so the waves will be peeling clean. This is excellent surf for those who know what they’re doing. Anyone else should stay out of the way. The afternoon holds onto 8ft with the same excellent conditions.
Stay sharp on Sunday the 9th of August – the afternoon swell is a whopping 10ft from the south, with a very long 15-second period. The energy is massive (3569), but the forecast says it’s too big for this break. Unless you’re a pro, give it a miss.
After that big Monday, the surf eases back down. The 12th of August sees some smaller but clean swells, with offshore winds again. The 13th stays clean but small. By the 14th, the rain comes in and the waves drop off again, marking the end of the real action in this window.
Barrinha is a fairly exposed spot, very consistent, and on a good day with that offshore wind, it’ll be a treat. Just remember, on the bigger days (over 8ft), it’s expert territory only.
Signing off,
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.
