The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right now, we’re looking at a bit of a slow start at Ribanceira. The first couple of days are a write-off with messy, onshore wind and poor surf. Friday (7th August) is a no-go with tiny, weak 1ft swell and a cross-off wind that’s just not doing it any favours. It’s not until Sunday morning (9th August) that we finally see something shaped up. The water is sitting at 67°, which is about a degree and a half warmer than usual for this time of year – nothing crazy, but you’ll notice it’s a touch more comfortable.
Sunday morning kicks things off with a clean 4ft southerly swell, and the wind is offshore. That’s a solid start. The swell period is a nice 12 seconds, so there’s some real push behind it. The combined energy is moderate (987). Sunday afternoon really steps it up though – 8ft of south swell with a cross-off breeze, and the energy jumps to 2412. That’s strong, powerful stuff. This is for experienced surfers only, as it’s pushing over 8ft by Monday. Monday (10th August) morning is the standout of the first week: 8ft south swell, offshore wind, and energy at 3032. That’s very strong. The waves will be clean, powerful, and lined up. This is the best on offer for the first week – a true highlight.
Tuesday (11th August) still looks good with 7ft and offshore wind in the morning, then glassy conditions in the afternoon with 6ft. The swell period is 11-12 seconds, so plenty of energy. The crowd situation at Ribanceira is listed as “sometimes” busy, so you might have a few out, but it won’t be a circus.
Wednesday (12th August) and Thursday (13th August) see a drop in quality with cross-onshore winds and choppy conditions. Thursday afternoon does offer a surprise though – a glassy 4ft swell with a very long 16-second period. That’s a groundswell, so it’ll be cleaner at the point and reef setups, but at a sandbar break like Ribanceira, it might break a little too straight. Still, glassy conditions make it worth a paddle.
Friday (14th August) is a solid day with 8ft from the SSE and offshore wind, then Saturday (15th August) fades out with weaker, smaller swell and cross-shore winds. From Sunday (16th August) through to Monday (17th August), it’s a real mess with onshore wind and short-period, choppy windswell. Not worth your time.
Then comes the second week’s standout. On Tuesday (18th August), we get a massive 13ft easterly swell with offshore wind and clear skies. The energy is 2823 – very strong. This is big, powerful, and only for experts. By Wednesday (19th August), it drops to 10ft with clean, offshore conditions and energy at 2078. Still excellent for experienced surfers. This is a long-range call, so it’s promising but not locked in yet. Keep an eye on it.
After that, the wind turns onshore again from Thursday (20th August) through Friday (21st August), and the swell fades. Saturday (22nd August) morning brings a small, clean 5ft south swell with offshore wind, but it’s short-lived.
Overall, the best surf is Monday (10th August) morning and the big stuff on Tuesday (18th August) and Wednesday (19th August). Don’t waste your time on the first few days.
Rusty.

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.
