The Lowdown

Alright, Rusty here. Let’s have a look at what’s happening at Ribanceira over the next couple of weeks.

Right now we are looking at a bit of a slow start, but there is a proper little window of clean, fun surf coming up. The standout is going to be Monday the 14th. The morning is your pick: a solid 5ft south swell, period at 11 seconds, so there is some good groundswell energy (535 combined energy) and light WSW cross-offshore wind. That’s going to produce clean, well-shaped waves. It’s a sandbar setup here, and fairly consistent, but keep your head up – crowds are possible. The water is about average for this time of year.

That Monday afternoon drops off a bit to 4ft, still clean but not as good. Tuesday the 15th turns smaller, around 3ft, and stays clean with light offshore wind, but it’s pretty ordinary. Wednesday the 16th morning brings back some energy with a 5ft south swell at 8-second period (415 combined energy). That's a shorter period wind swell, but with clear skies and light offshore wind, it will be clean and fun for an intermediate.

From Thursday the 17th onward, things go quiet. We get onshore wind from the north-northeast and northeast, blowing up to 16 mph. It stays poor right through the next several days with the swell dropping to near nothing. We are looking at a dry spell from Thursday the 17th all the way through to the morning of Tuesday the 22nd – that’s about five days of very little to no surf.

Tuesday the 22nd afternoon shows a brief change: a 5ft easterly swell shows up but with cross-shore wind and the quality is still poor. Not worth getting excited about.

Now, the second week looks quiet generally, but there is a potential highlight on Thursday the 24th. The morning shows a 5ft east swell (405 combined energy) with glassy conditions. That east swell might offer something, but the period is short at 8 seconds, so it will be a bit weak and soft. If you are keen, get out early when it’s glassy. After that, it drops away again into small, ordinary conditions through to the end of the window.

So the bottom line: if you can, get out Monday the 14th morning – that’s your best shot at proper clean surf with some push. After that, it’s a long wait until late in the month.

Stay wet,
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.
