The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Ribanceira. The next week or so is a proper story of two halves – a slow start, then a nice pulse of cleaner, solid swell, before it gets messy again.
We kick off Wednesday (5th August) with glassy conditions but tiny surf. Wednesday morning sees 3ft of SSE swell at a short 10 seconds, with glassy wind. The combined energy is weak at 147. Water temp is 68°, feeling a touch warmer than usual for the time of year. It’s surfable, but very ordinary. Wednesday afternoon is even smaller at 2ft, still glassy. Thursday (6th) drops even more, down to 2ft in the morning with glassy conditions, but it’s pretty gutless.
We have a few days of this low-energy stuff, but it’s not until Sunday (9th August) that things turn around properly. The wind swings offshore from the SSW at 9 mph, and we get a 5ft SSE groundswell (11 seconds) building through the morning. The energy jumps to moderate (855). This is the first true standout – solid, clean, and lined up. Sunday afternoon is even better with 6ft S swell and the same offshore wind, combined energy climbing to 764. This is a good window for Ribanceira.
Monday (10th) keeps the good run going with offshore SW wind and a 6ft S swell (13 seconds) in the afternoon, packing moderate energy (943). With the longer period, it’ll have some good shape. Tuesday (11th) holds similar 6ft S swell, offshore WSW wind, and clean conditions through the day.
We get another highlight on the morning of Friday, 14th August. The wind is offshore from the WSW at 6 mph, and the swell is 6ft from the south with a 13-second period. The combined energy is strong at 1452. This will have some punch and clean faces for sure. The afternoon stays good, with 6ft S swell and offshore wind.
Be aware that from the 15th onwards, it gets rough again with onshore or cross-onshore winds and choppy seas, so that clean window closes. The following Monday (17th) and Tuesday (18th) do flirt with glassy small stuff, but it’s back to very small waves. There’s a potential little glassy morning on Thursday, 20th August, offering 3ft of S swell, but it’s a long way out and likely a flash in the pan.
Overall, the best of the 16 days is definitely the stretch from Sunday, 9th August through to late on Friday, 14th August. If you can get out there, especially on the Sunday or Friday mornings, you’ll score clean offshore lines from the S swell at Ribanceira (sandbar). Crowds are possible here sometimes, but if you pick your morning right, it’s well worth it.

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.
