The Lowdown
Alright, let's cut through the noise. The next couple of days are a bit of a bust, so don't rush out. Saturday the 8th is choppy and messy with a cross-onshore breeze and a lumpy 7ft south swell. Not worth the paddle.
Sunday the 9th is a little cleaner with a cross-offshore wind, but the swell is down and it's still marginal. You're looking at 4ft to 7ft, and the tide could mess with it. Not the day to make a plan around.
Now, Monday the 10th is where things fire up. The combined swell energy jumps to 2487 – that's a serious push of water. The morning shows a 7ft southwest swell with a 12-second period and a clean offshore wind. This is the standout of the first week. Ribanceira, this sandbar, handles it well and is fairly consistent. The water temp is 67°, which is normal for this time of year, but that won't matter when the waves are this good. It's going to be pushing it for beginners, but for anyone with a bit of experience, this is the session.
Tuesday the 11th is still good, but a step down. The morning is glassy with a 7ft southwest swell and energy at 1238. It's clean and playful. However, the afternoon brings some light rain and a cross-onshore breeze that will take the shine off it.
Wednesday the 12th and Thursday the 13th are a bit messy again. Onshore winds and rain on Wednesday, and while Thursday has a longer-period groundswell at 15 seconds, the cross-onshore wind will chop it up. The energy is there, but the surface won't be. We're looking at 5ft to 6ft – again, not terrible, but not clean.
Friday the 14th is another good one. The morning has a moderate offshore wind, a clean 6ft south swell, and energy at 1145. It'll be a bit smaller than Monday but still very surfable. The afternoon picks up in size to 8ft, but the wind goes cross-offshore and conditions are a bit less perfect.
The weekend of the 15th and 16th is a letdown. The swell drops off on Saturday, and by Sunday it's mostly windswell with a short 6-second period. The energy just fades away. This is where the gap starts.
From Sunday the 16th afternoon through Wednesday the 19th, it's mostly flat or tiny. We're talking about a run of days with minimal surf, so don't get your hopes up. The energy readings are down in the low double digits, so there's nothing doing.
We start to see a pulse of life again on Friday the 21st, but it's pretty ordinary. A little 4ft SSW swell with clean conditions, but low on energy. Not a head-turner.
The real promise is for Saturday the 22nd. It’s over a week away, so take it with a grain of salt, but the models are showing a fresh offshore wind and a building SW swell – 6ft to 6ft. The afternoon looks better with the energy jumping up to 1173. It's a bit more of a long-range call, so it's promising but not certain.
Sunday the 23rd fades out again, with smaller surf and a cross-offshore breeze.
So, in short: the best windows are Monday the 10th and the morning of Friday the 14th. Both have clean winds, good size and solid energy. The Monday is the bigger, more powerful day, so if you're only getting one session in, make it that one.

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.
