The Lowdown
G’day, Rusty here. Let’s look at Ribanceira in feet and miles per hour, same deal—just a different ruler.
It’s a slow start, no doubt. Friday the 4th is flat and rubbish. Saturday the 5th brings a pulse of 3ft to 4ft from the south, around 9 seconds, with offshore wind making it clean but the waves are just ordinary. There’s some energy in the water but nothing to write home about.
Now Sunday the 6th is the real deal. That morning, a solid 8ft south swell with an 8-second period rolls in, and the wind is offshore from the southwest. Energy is moderate but punchy. By the afternoon it pushes to 8ft from the south, period lengthening to 10 seconds, and the energy jumps up strong. Wind stays offshore but freshens. This is big—over 8ft—so only for experienced surfers. The waves will be powerful and clean, though the short period keeps things a bit lumpy at this sandbar. It’s the standout of the whole outlook.
Monday the 7th holds with a 6ft south swell in the morning, offshore wind, clean. A good session for intermediates. Afternoon wind swings onshore and quality drops.
Tuesday the 8th through Saturday the 12th is a dry spell. Swell drops under 3ft, winds go onshore or cross-on, scores are zero. There’s a glassy moment on Thursday the 10th afternoon and Friday the 11th morning, but with only 2ft and 1.0ft of swell, it’s not worth paddling out.
Sunday the 13th brings 6ft to 6ft from the south-southeast, short 7 to 8-second period, but cross-onshore wind spoils it. Monday the 14th gets bigger—8ft to 8ft—but it’s onshore and messy.
Then we turn. Tuesday the 15th: morning sees 7ft from the east with an 8-second period, light cross-offshore wind, energy moderate. Clean and surfable. Afternoon holds at 6ft.
But the true gem is Wednesday the 16th. Morning brings a 7ft south swell, 9-second period, light cross-offshore wind, and energy through the roof. Expect very good surf conditions—clean, powerful, consistent. This is the standout for intermediates and above. Afternoon drops to 3ft but period stretches to 12 seconds, a long-period groundswell that’ll wrap the sandbar nicely.
Thursday the 17th and Friday the 18th are small and ordinary—2ft to 3ft from the south, periods up to 14 seconds, but weak energy. Glassy moments Friday afternoon, but little push. Saturday the 19th fades to 2ft and we’re done.
Best bets: Sunday the 6th for big, clean offshore swell (experts only) and Wednesday the 16th for that pumping 7ft south groundswell under light winds. Both are standouts. The rest is small or a waiting game.
Stay keen.
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.
