The Lowdown
Alright, mates, Rusty here. Let's cut through the noise. We've got a long, flat stretch to kick things off, then a proper swell train rolls in, and there's one or two days that are an absolute must-surf. Get ready to wait, but it'll be worth it.
The first several days are a write-off. From Saturday the 15th through to about Wednesday the 19th, we're looking at tiny, weak surf. There's just nothing on offer. The energy is in the single digits and low double digits (7-97), and whatever's out there is chopped up by cross-onshore breezes. Not worth your time. This is the kind of dead spell where you just accept the flatness.
Things perk up a touch around Friday the 21st, as a new swell fills in to around chest-shoulder high (1.7m) with energy spiking to 620. But the wind is all wrong, cross-shore and messy. You might snag a closeout or two, but it's not the clean stuff we're after.
Now, for the good part. The standout window is Monday the 24th and Tuesday the 25th of August. Monday looks powerful and clean. We're talking solid overhead waves at 2.5m, with a long 15-second interval (proper groundswell) and light cross-offshore winds. The energy reading is massive (2942 in the morning), and quality wise, this is the pick of the bunch. The water temps are about normal, around 66°.
Tuesday the 25th is just as good. The swell backs off a bit to around head-high plus (1.9m), but the wind goes dead glassy, especially in the morning. With a 14-second period and high energy (up to 1388), it'll be clean, powerful, and probably pretty perfect. If you want the best combination of size and conditions, this might be your day.
After that, it gets tricky. Wednesday the 26th sees a monster 3.5m swell hit. That's way too big for this break, and it's only going to be for experts. With light onshore winds predicted, it could be a total mess. Honestly, at that size, the spot looks more suited for a kite surfer, not a paddle surfer.
The end of the month is a letdown, with the swell backing down into lumpy, cross-onshore slop that never cleans up. The energy fades out by the 28th, and we're back to waiting. The long-range stuff is promising but less certain, so keep your fingers crossed.
So here's the plan: be patient. Don't bother paddling out this week. The moment that matters is the early part of next week. Monday the 24th and Tuesday the 25th of August. Big, clean, and powerful. That's where you want to be.
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.
