The Lowdown
Alright, Rusty here, let's have a look at what's on the menu for our local sandbars.
Right off the bat, we’ve got some swell on the way, but honestly, the start of this run is pretty ordinary. The waves are there, but the conditions are just not playing ball. There’s a bit of a wait before we get anything you’d want to write home about.
The first session that’s worth your time doesn’t roll around until Saturday afternoon, the 5th of September. We’re looking at chest to head-high sets around 4ft from the South with a short period, so it’ll be a bit fat and mushy, but the wind will be light and clean, making it surfable. You'll find the combined energy moderate at 434, so there’s enough push to have some fun.
Sunday the 6th morning keeps that clean cross-off breeze going, with 4ft from the SSW, and it’ll be clean again. Not the best waves of the month, but a solid enough weekend session.
Now, if you’ve got patience, Monday morning the 7th of September is your standout. This is the one. The swell jumps up to a solid 7ft from the SSW, with a nice 10-second period. The combined energy is pumping hard at 1429, which is strong wave energy, so this is proper stuff. The wind is light and clean, glassing it right off. This is going to be a proper session for experienced surfers. Keep in mind, at 7ft, it’s pushing the limits for beginners. It’s not quite “experts only” territory, but it’s getting serious. The optimum direction is SE, and this is coming in from the SSW, so it won’t be the absolute perfect angle for Barrinha, but the quality of the swell and the clean conditions make it the best bet in the whole outlook.
After Monday, things get messy again. The wind swings onshore and chops everything up for the rest of the week and into the next. There’s a long stretch of poor conditions until we get a little glimmer on Wednesday morning, the 16th of September. That morning brings a glassy 4ft S swell with a 10-second period, and the combined energy is a moderate 429. It’ll be a clean, fun little session if you’re around, but it’s a long way out, so keep an eye on the forecast.
Overall, Monday the 7th is your big red circle on the calendar. Get out there.
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.
