The Lowdown
Hey, Rusty here, checkin' in on Ribanceira. Gonna level with ya, the start of this forecast is a proper bummer. We gotta wait a while before anything decent shows up.
Water temp is about normal for the season, nothing crazy. But the swell? For the first week or so, it's mostly a bust. Wednesday the 16th kicks off with a weak 4ft south swell at 8 seconds. The morning is flat and glassy, but the conditions are ordinary with a combined energy of just 349. The afternoon gets messy with a cross-off breeze.
Then we hit a dead zone. From Thursday the 17th all the way through Monday the 28th, it's a long stretch of poor surf. The winds are onshore or from a bad angle, and the swell drops to almost nothing – we're talking 1ft or less with energy figures barely into double digits. There's a clean offshore wind on Tuesday the 22nd, but the swell is a pathetic 0.7ft. Not worth the wax.
Finally, things start to turn around. On Monday the 28th afternoon, there's a tiny 3ft south swell (energy 160) that's clean, but still just "surfable". The real highlight is Tuesday the 29th. That morning we get a clean 4ft south groundswell with a nice 11-second period and a light east wind. The combined energy hits 548 (moderate), and the forecast says "good surf conditions". That's the session to aim for. The afternoon gets a bit dicey with an onshore breeze, but the morning is solid.
Now, for the big news, but it's a long way out. Thursday the 1st of October is over a week and a half away, so be patient, but man, it looks like a beast. An 8ft south swell with a 10-second period and a light offshore wind from the SW? That's "very good surf conditions" with a massive combined energy of 1325. That's expert-only territory, but if you've got the skills, that's the one to wait for. It's gonna be a quiet stretch before it, but a proper pulse of swell is on the horizon.
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.
