The Lowdown

Alright, let's get into it. The surf's looking a bit slow to start, but we've got a solid run of waves coming through.

The first few days are a washout. Thursday the 20th of August is a total write-off with tiny, 2-foot onshore slop, so don't even bother. We'll have to wait for the action to kick in.

Friday morning the 21st sees a change. The swell picks up to 5 feet from the SSW, period a short 7 seconds, but the wind is offshore and clean. It's surfable, but nothing to write home about. The real show starts on Saturday the 22nd. That morning we've got 7 feet of S swell with a light offshore breeze, and the combined energy is already pumping at 792 (moderate). By Saturday afternoon, it jumps to 8 feet from the S, and the energy rockets up to 1604 (strong). The conditions are looking very good, with clean, cross-off winds.

Sunday the 23rd keeps the quality high. The morning has 6 feet of S swell, glassy offshore wind, and an energy reading of 875 (moderate). The afternoon pushes it to 7 feet with a 12-second period (groundswell) and energy hits 1299 (strong). This is a standout session.

Now, Monday the 24th is the big one. The morning brings a solid 10 feet of S swell with a very long 16-second period. The energy is a massive 4132 (very strong). This is excellent, but only for experienced surfers, as it's over 8 feet. The wind is light offshore, so it will be clean. This is your best bet for the whole forecast period, but it's a big, powerful wave. The afternoon drops to 8 feet, but the wind goes cross-shore, making it messier.

Tuesday the 25th morning is a treat. The swell drops to 7 feet from the S, still a nice 13-second period, but the wind is glassy. The energy is 1376 (strong). This is a perfect window for the intermediate crowd, with clean, calm conditions. The afternoon goes onshore, so get out early.

The quality falls off a cliff after Tuesday. From Wednesday the 26th through to the end of August, it's all onshore wind and junk. We're looking at a solid 5-day gap of poor surf. The swell drops, and the wind is from the NNE, ruining the shape.

We get a tiny glimmer on Friday the 4th of September. The morning brings 5 feet from the S with a gentle offshore wind, and the energy is 553 (moderate). The afternoon is similar with 5 feet. It's a return to good, clean conditions, but it's a long way off, so keep an eye on it.

The water temp is about 67°, which is pretty normal for this time of year here at Ribanceira.

For the standout, hands down, it's Monday the 24th of August morning. That 10-foot S swell with a 16-second period and light offshore wind is a dream for the experienced crew. The energy is insane. The secondary pick is Tuesday the 25th morning for the glassy, 7-foot perfection.

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.
