The Lowdown
Alright folks, Rusty here. Let’s break it down for the next couple weeks. It’s gonna be a slow start, so don’t bother waxing up just yet.
The first few days are essentially flat and not worth your time. We’re looking at a dry spell from now through Wednesday, just small, weak swell and no quality.
Things get a little interesting on Friday afternoon, when a south swell pushes through at about 5ft, with a 9-second period, and a cross-offshore breeze keeping it clean. It’s not firing, but it’s a start. The energy is still only moderate at 398, so don't expect much.
Saturday is a bust. We get a strong, stormy 7ft of south swell, but the north winds are blowing hard and putting chop all over it. That’s a kite-surfing setup, not a surfing one.
Sunday sees the swell hold, but it's hit or miss. The morning has some size at 7ft, but the wind is a bit messy. The afternoon is better, with the wind easing to a light breeze and cross-offshore, the swell settling to about 6ft. It’s clean, but it’s not the best of the window.
Now, Monday, August 10 is where it starts to get serious. We’ve got a solid 6ft of south swell at an 11-second period, with true offshore light wind all morning. The waves will have some push and shape. This is a proper day. The water temp is 20°, which is a bit warmer than usual for this time of year, so it ain’t freezing. The energy is strong at 1360, so there’s plenty of juice.
Monday afternoon holds up, and Tuesday is solid as well. The Tuesday morning session looks good with 5ft on a 12-second swell and clean offshores. Wednesday morning is also nice, with 5ft and glassy conditions. These couple days are the peak of this run.
After that, it gets a bit ordinary into Thursday and Friday. The wind goes onshore and it gets messier. But then, look out for Saturday, August 15. That’s the big one. We’re looking at 6ft of south swell on a 13-second period, and the wind drops to zero—total glass. It’s going to be clean, powerful, and organized. That’s the day to circle on the calendar. The energy is high at 1318, and with that long period, it’s going to have some serious push to it. The only caveat is, with a long period like that, point breaks and reefs will handle it better than a beach break, but if Ribanceira is working, it’ll be special.
After that, the swell fades again. The wind turns onshore and blustery on Sunday, and the surf gets smaller and weaker through the following week. The last few days are just small leftovers.
So, bottom line: get out Monday the 10th for a great, clean south swell with offshore winds. But the real standout of the whole stretch is Saturday the 15th. It’s further out, so it’s a promise, not a guarantee, but with that strong, long-period south swell and no wind, it has all the makings of a legendary session.
Rusty, out.

Information about the Ribanceira Surf forecast
The above surf forecast table for Ribanceira provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ribanceira can be found by selecting the local surf guide option on the grey menu. Our Ribanceira 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 (Ribanceira) 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 Ribanceira 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.
Ribanceira is 6 km (4 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.
