The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming our way for the next couple of weeks.
The forecast period kicks off with a bit of a flat spell, so don’t bother paddling out just yet. It’s not until Saturday the 12th of September that things start to look interesting.
Saturday the 12th of September is the standout morning. Ribanceira will see a solid, clean 8ft swell from the SW with an 11-second period, and a moderate offshore wind from the SW keeping it clean. The combined wave energy is strong (1516). That's proper groundswell energy, and with the wind in your face, it should be a good session for the intermediate crew. The swell is getting up there, a bit much for beginners, but not quite full-on expert territory. The water temp is about average for this time of year.
Sunday the 13th of September has dropped off a bit. The morning offers a 4ft SE swell with SW offshore winds, but the period is short at 8 seconds, so it’s surfable but a bit average. Not worth getting excited about.
Tuesday the 15th of September has a brief window with a clean 3ft S swell in the morning and offshore WSW wind, but again, it's ordinary. Afternoon blows up with a messy 7ft S swell and 7-second period – no good.
Wednesday the 16th of September is the next real highlight. Morning delivers a lovely, clean 7ft S swell with gentle offshore SW wind (moderate energy at 1408). The afternoon is even bigger, with 8ft from the SSE, long 11-second period, and clean conditions. This is a solid, long-period groundswell. With that size, it’s expert territory, but the quality is there. Watch out for those longer waits between sets.
After that, it gets messy again for a stretch with onshore winds and poor surf.
Monday the 21st of September has a nice early session. The morning is glassy with a 4ft S swell at 12 seconds and a combined energy of 552. For a calm, clean day with some proper period, it’s a chance for a good paddle.
The rest of the forecast goes quiet and small again, with most days offering poor conditions until the last few days of the window. Nothing else is worth specifically calling out.
Alright, I’m off to check the tide. Catch you in the water.
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.
