The Lowdown
Alright, let me talk you through what’s happening at Ribanceira.
The best waves of the whole stretch hit first thing Monday 14th September. We’ve got a 5ft groundswell from the SSW running at 11 seconds, and the combined swell energy is 1157 (strong). Wind is offshore from the SW at 15 mph – clean, groomed, glassy. Water temp is 62°F, which is about 3 degrees cooler than normal, so a wetsuit is non-negotiable. This is a sandbar, fairly consistent, and it loves that southerly juice. Crowds are possible, so try to be first out. That morning is the standout, no doubt. By afternoon it drops to 4ft and the quality goes ordinary.
Tuesday 15th and Wednesday 16th are small and clean but not worth planning a day around – waves around 3ft in the mornings.
Then from Thursday 17th through Monday 21st September, it goes flat and ugly. Onshore winds from the north and northeast, wave heights dropping to less than a foot, and energy readings as low as 9. That’s a solid five-day dry spell. The Monday 21st afternoon does pop a 7ft east swell, but it’s cross-onshore and messy – might be more fun for the kiteboarders than paddle surfers.
Tuesday 22nd is the best of the second week: 6ft to 6ft of east swell, clean cross-off winds from the south, and energy readings around 485 to 562 (moderate). Not as clean as the first Monday, but it’s something.
Wednesday 23rd morning has 5ft with light offshore wind from the SSW, but the swell is short period (9 seconds).
The rest of the month fades into small, weak, or onshore slop. Monday 28th September shows a 6ft southern pulse with offshore wind and 547 energy, but at only 7 seconds it’ll be soft and bumpy.
So really, Monday morning the 14th is your one true session. Everything else is either waiting or average. Get on it.

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.
