The Lowdown
Alright, surfers, Rusty here. Let’s get into it. The next couple of weeks are a bit of a mixed bag, but there are definitely some windows to get wet.
The first few days are rough. Saturday the 8th is a total washout with onshore junk and poor conditions. Sunday the 9th brings a shift, with a clean offshore wind but the swell drops off and the period is short. It’s not really worth your time. The real action starts to build through Sunday afternoon and into Monday the 10th. We’ve got a solid pulse of south swell pushing through, with the energy climbing to strong levels. This is when it starts to get good.
The standout of the whole window is Monday morning at Ribanceira. We’re looking at a solid 8ft of south swell with a proper 13-second groundswell period, and the wind is gentle offshore. It’s going to be clean and powerful. This is the pick of the bunch for experienced surfers. The water temp is sitting at 67°F, which is about average for this time of year, so a spring suit is still the go-to.
Tuesday the 11th is also a good shout, with glassy conditions and clean 6ft waves. It’ll be a bit softer than Monday, but still fun. After that, the middle of the week gets ordinary again with onshore winds and messier conditions. The swell stays but the quality drops right off.
The next real highlight is the morning of Friday the 14th. Another pulse of south/south-southeast swell is on the cards, with 6ft waves and a moderate offshore wind. The energy is still strong, and the conditions should be very clean. It’s a good bet for a solid session that day.
After that, the surf slowly fades. We get a brief glassy morning on Saturday the 15th, but the swell is dropping. Then it’s a long, poor stretch from the 16th through the 21st. There’s a bit of a gap there with no real recommendations, mostly onshore junk and weak, short-period waves. It’s not looking good.
The final hope is the morning of Saturday the 22nd. The swell has dropped to a modest 4ft, but the wind is offshore and the period has stretched back out to 13 seconds. It’ll be small but clean and might be worth a longboard. It’s nothing special, but it’s the only thing breaking the monotony.
So, to sum it up: Monday the 10th is your best bet for size and power, with Friday the 14th a close second for cleaner conditions. The rest is a waiting game. Hang in there.
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.
