The Lowdown
Alright, let’s have a look at what’s coming up for Ribanceira. This is a sandbar set-up that needs a bit of love from the swell direction, and it’s pretty sheltered. The water temperature is sitting at 66°F, which is about average for this time of year, so nothing unusual there.
The standout window is a short one, and it’s right at the start. Tuesday morning, August 25, is your moment. We’ve got a solid 6ft groundswell out of the south, with a nice 12-second period, and the combined energy is pumping at 1100 (moderate to strong). The wind is glassy – just a whisper from the NNW at 3 mph – so the surface will be clean and inviting. It’s a fairly consistent break, and while crowds are possible here, with conditions this good, it’s worth sharing the lineup. This is the best on offer, no question.
After that, things drop off fast. Tuesday afternoon on the 25th the wind swings onshore from the ENE at 9 mph, and the surf turns poor. The rest of the week is a write-off – Wednesday through Friday sees messy, choppy conditions with cross-onshore winds and building energy that’s just not working with the wind. By Friday morning the 28th, swell drops to 2ft and energy plummets to 119, so don’t bother.
Saturday and Sunday the 29th and 30th have clean, offshore winds, but the swell is tiny – 1.0ft to 2ft with short, weak periods. The energy is down in the teens and low 40s, so it’s basically flat.
Monday the 31st stays small but clean, with 3ft swell and a 7-second period, but the energy is only around 62. Not worth paddling out for.
There’s a brief pulse around Tuesday and Wednesday, September 1 and 2, with 7ft to 8ft SSE swell, but the wind is messy and the period is short at 8 seconds. The energy is moderate (437–653), and while the waves are there, the quality is marginal at best. This is really only for the keen, and even then, it’s not great.
From Thursday September 3 onward, it’s mostly small, weak, and ordinary. Friday September 4 has a morning window with 3ft ESE swell, glassy wind, and 10-second period, but the energy is only 221, so it’s just surfable, not exciting. The rest of the first week of September fades into tiny, short-period leftovers.
Bottom line: if you want the best, you’ve got Tuesday morning August 25. The rest of the 16-day window is slim pickings, with a lot of gaps and only marginal conditions. With several breaks in the area being fairly consistent, it’s not unusual for things to dry up like this – but the forecasts can change, so keep an eye 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.
