The Lowdown
Alright folks, Rusty here. The swell window’s been pretty stingy, but we’ve got a few windows to work with. Let’s get into it.
We’re looking at a long, slow start. The first few days are a write-off – tiny, weak, messy. No point even paddling out. From Saturday 22nd, the energy starts to build, but it's still shaky. The real turning point comes Thursday 23rd morning. The water at Barrinha is sitting at 61°, which is a solid 5° colder than normal for this time of year – that’s a lot colder than usual, so bring a good steamer.
The standout window is Thursday 23rd morning. The swell jumps to 6 ft from the south, with a short period of 8 seconds. The combined energy hits 329 (moderate), and the wind is offshore from the southwest at 9 mph. That’s clean, lined-up surf. It’s a beach break, so with that short period, it’ll be a bit walled-off, but the offshore wind will keep the faces nice. This is the best on offer. In the afternoon, the swell holds at 6 ft (395 energy) and the wind goes cross-off, so you can still get some good ones, but that morning glass is the pick.
Friday 24th morning is a glassy backup – 5 ft swell from the SSE, glassy conditions. The energy is moderate (254), but the period is still short, so it’ll be a bit fat. Good for a quiet session if you missed Thursday.
After that, it drops off again. Saturday 25th afternoon has a tiny 2 ft glassy window, but it’s weak. The next real shot is Thursday 30th morning – 4 ft from the east, clean with a cross-off wind from the SSW. The energy is moderate (333). Not a standout, but a solid session if you’re keen.
The second week gets interesting but messy. There’s a big pulse of energy on Friday 31st and Saturday 1st August – 7 ft to 8 ft east swell, with energy readings from 959 all the way up to 1697 (very strong). But the wind is cross-on from the north, so it’s going to be choppy and lumpy. For a beach break, that’s a kite-surfing setup, not a paddle-surfing one. The swell is too big for beginners and the conditions are rough. Unless you’re an expert and hungry for a war zone, I’d give it a miss.
Sunday 2nd August drops back to 5 ft, but still cross-on and messy. The week closes out with a clean 3 ft cross-off pulse on Sunday afternoon. Not much power.
So, bottom line: Thursday 23rd morning is your best bet. Get out there early for the offshore, clean conditions. The rest is a mixed bag of waiting and watching.
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.
