The Lowdown
Alright folks, Rusty here. Let’s look at the next couple of weeks at Ribanceira. It’s a sandbar setup, pretty consistent, and it works best with a swell from the south. The water temp is sitting right around 66°, which is dead average for this time of year, so no surprises there.
The start of the period is a bit of a write-off, I’m not gonna lie. We’ve got a fair bit of waiting to do. The first few days are messy, with a lot of onshore wind and choppy conditions. On Wednesday the 2nd, there’s some swell, about 7ft from the southeast, but the wind is cross and it’s just not clean. You’re better off waiting.
We’ve got a real gap here. Thursday and Friday are pretty poor. There’s a brief flicker on Friday morning the 4th, with a small 2ft south-east swell and a clean offshore wind from the SSW, but at only 106 wave energy units, it’s weak. Not really worth paddling out for.
The first real sign of life comes on Saturday the 5th. The afternoon looks alright. We’re looking at 4ft from the south with a clean, gentle offshore wind from the southwest. The swell period is a short 8 seconds, so it’ll be a bit fat and inconsistent, but the energy is moderate (434 units). It’s surfable, and the wind is good.
Sunday the 6th is a mixed bag. The morning has 4ft from the south-southwest with light offshore winds, but it’s just ordinary. The afternoon gets a bit bigger at 6ft, but the wind swings onshore and it gets choppy again.
Now, here’s the standout. Monday the 7th. This is the one. The morning at Ribanceira is looking prime. We’ve got a solid 7ft swell from the south-southwest, with a 10-second period, and a clean, gentle offshore wind from the southwest. The wave energy is strong at 1429 units. This is going to be a proper session. Clean, powerful, and well-shaped. The waves are a bit big for beginners, but for any intermediate surfer, it’s going to be excellent.
After that, things get messy again. Tuesday the 8th has onshore winds, and the rest of the week is a mix of cross-shore junk and onshore slop. There’s a couple of small windows, like Thursday the 10th morning with flat, glassy conditions, but the swell is tiny at 1.0ft.
The second week is a tough watch. There’s a bit of a swell on Friday the 11th, with 6ft from the SSW, but the wind is a howling 22 mph offshore. That’s fresh, strong wind, making it a challenge. The setup looks more interesting for kite surfing than paddle surfing that day.
The best prospect in the second week is the morning of Wednesday the 16th. It’s a glassy, clean morning with a 4ft south swell coming in at 11 seconds. The energy is moderate (429 units), and the conditions are perfect. It’s a promising window, but it’s a long way out, so keep an eye on it.
So, to wrap it up: the absolute best session on offer is the morning of Monday the 7th. That’s your one. Make it count. The rest is a lot of waiting and hoping for the forecast to change.
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.
