The Lowdown
Alright, folks, this is Rusty, and I’m looking at what’s cookin’ for our local sandbar, Ribanceira. It’s a bit of a slow start, but once it gets goin’, we’ve got some real moments to look forward to.
Right now, we’re in a bit of a dry spell. The first few days are a write-off, with Wednesday the 12th looking messy – cross-on winds and poor surf. That pretty much carries through the rest of the week and into the weekend. From Thursday the 13th, we see a pulse of clean, offshore wind, but the swell’s still a bit raw and the scores aren't really there for a standout. We’ve got a real gap from the 14th all the way through to the 19th, with nuthin' but small, choppy, or onshore junk. It’s a long stretch of nothin’.
Then, on Thursday the 20th, we get a little glimpse of hope. The morning is glassy, with a small 5ft S swell. The energy is weak (316), so it’s just something to get wet on, nothin’ to write home about. The session is more about the peace than the power.
Now, hold on to your board, because the real standout window is Friday the 21st. The morning is the pick of the first week. We’ve got a clean 5ft groundswell rolling in from the S with a solid 12-second period. The wind is light and offshore from the SSW, making for clean, lined-up waves. The combined energy is moderate at 756, so there’s some push behind 'em. This is the one to circle. The afternoon still has some shape, but the wind goes cross-shore, so get it early.
After that, Saturday the 22nd is still surfable with clean conditions, but the swell backs off to 3ft, and it’s a bit more ordinary. Then we hit another flat and choppy patch from Sunday the 23rd through Monday the 24th.
But if you’ve got patience, the second week will reward you. Tuesday the 25th is another absolute standout. The morning is pure glass, with a clean 6ft S swell at 12 seconds. This is strong wave energy (1173) and the wind is nil. It’s gonna be epic. The afternoon holds up with clean conditions and the same size. This is a true highlight.
Wednesday the 26th keeps the goods coming with a solid 5ft S swell and moderate offshore winds, keeping it clean and fun. The swell energy is still strong (927). The afternoon gets a bit tricky with the direction shift, but it’s still rideable.
Finally, Thursday the 27th rolls in with a bigger 7ft swell from the ESE. This is getting into the expert zone, but with moderate offshore winds from the SW, it’s going to be a hall of fame session for the crew who can handle it. The energy is strong (950), and it’s a proper way to end the run.
So to boil it down: The best on offer is the morning of Friday the 21st for clean, quality lines, and the glassy morning of Tuesday the 25th for the biggest, cleanest swell of the period. Don’t sleep on Thursday the 27th if you’ve got the skills for a bigger, more powerful wave.
Rusty, 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.
