The Lowdown

Alright, folks, Rusty here. Let me break down what's cooking at Ribanceira over the next couple of weeks. We've got a pretty quiet start, but there's a few windows of opportunity to keep an eye on.

First up, the water temp is sitting at about 65°, which is pretty much what you'd expect for this time of year. Not a shocker, just standard.

The next few days are a write-off. From Wednesday the 26th all the way through to Sunday the 30th, the surf is either poor or tiny. We're talking onshore winds, a bit of chop, and energy levels that are just sad. The best of that bad lot might be Saturday the 29th morning with a bit of offshore wind, but the swell is only 1ft – not worth paddling out for.

Monday the 31st is more of the same: onshore wind and messy waves. Then, things start to get interesting.

Tuesday, September 1st is our first real standout. The morning brings a clean 7ft swell from the SSW, with a moderate offshore wind from the SW. The wave energy is solid (575), and the wind is keeping things clean. This is the best session on offer for the near future. The break is a sandbar setup that's fairly consistent, so it should be holding. Just be aware that crowds can be a thing here sometimes.

After that, we get a bit of a lull. Wednesday the 2nd has some small, clean waves but nothing special. Then Thursday, September 3rd is another good one. The morning is looking clean again with a 6ft S swell, light offshore wind, and good energy (713). The period is a nice 10 seconds, so you'll get proper groundswell lines. This is another top pick.

Friday the 4th is a bit of a mixed bag – the morning is glassy, dead calm, but the swell is a small 3ft. Fine for a longboard if you're keen.

The second week is a bit more of a gamble. There's a pulse of energy showing up around Thursday, September 10th. The morning has a solid 8ft swell from the SE with a 10-second period, and the energy is pumping (1296). However, the wind is onshore from the NNE, which is going to mess it up for paddle surfing. There's a chance the afternoon is even bigger (7ft, 1505 energy), but again with the onshore wind. For a sandbar, this setup looks more interesting for the kite crew than for us on a standard surfboard, unless you're an expert looking for a challenge.

Other than that, the middle of the second week is mostly small, clean, and ordinary. The period on the 7th and 8th looks long, which could mean better shape at a point break, but Ribanceira is a sandbar, so those long-period swells from the south might break a bit too straight for ideal barrels.

So, to sum it up: Tuesday, September 1st and Thursday, September 3rd are your best bets. Get out there for the morning sessions when the wind is offshore. The 10th has size but the wind is a bastard.

Stay stoked.

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.
