The Lowdown

Alright folks, Rusty here. We’ve got a solid run of surf coming up at Ribanceira, but you’ll need to be patient for the first few days. The week starts off a bit messy, but there’s a real gem waiting for us.

The early part of the window is a write-off for quality surfing. Friday and Saturday (7th and 8th of August) are all about leftover energy with poor conditions, so don’t bother. We’ve got a couple of days of marginal surf on Sunday, but things start to shift on Sunday afternoon. The combined swell energy is moderate (934), and it’s a sign of things to come.

The real standout is Monday the 10th of August. The morning session at Ribanceira is the pick of the entire forecast. You’re looking at a solid 8ft south swell with a 12-second period, producing strong wave energy (2726). The wind is offshore from the southwest, which is going to keep those lines clean and peeling. This is excellent surf, but with that size, it’s really for experienced surfers only. The afternoon eases a bit to 7ft, still with a clean cross-off breeze, and very good surf.

Tuesday the 11th is another cracking day. We’ve got glassy conditions in the morning with a light WSW wind, and the swell holds at 6ft from the south, period at 12 seconds. The energy is healthy (980), and the afternoon goes completely glassy with zero wind. That’s a dream session waiting to happen.

We get a bit of a north wind kicking in on Wednesday and Thursday (12th and 13th), which brings some cross-on conditions and a drop in quality. The swell is still there, but the wind makes it a bit ordinary. However, Friday the 14th of August is worth setting an alarm for. Light offshore winds from the SSW and SW with a 6ft to 6ft swell from the SSE, period around 13 seconds. The energy is strong (1197-1226), and the conditions are clean. This is a very good day for anyone who can handle it.

The following weekend (15th and 16th) remains surfable, with glassy or clean conditions and smaller, more manageable waves in the 5ft to 6ft range. The energy drops a bit but it’s still fun.

After that, the second week goes quiet. From Monday the 17th through to the end of the 22nd, the surf is mainly poor or marginal. There’s a brief flash of glassy conditions on Wednesday the 19th with a 5ft south swell, but the energy is weak (333) and the conditions are just ordinary. The rest of the week is riddled with cross-on and onshore winds, making it a write-off for paddle surfing. Honestly, with those winds and the size, the setup looks more interesting for kite surfing than a traditional surf.

So, if you’re picking a day, Monday the 10th is the absolute standout for the big, clean, powerful stuff. Friday the 14th is your next best bet for a slightly smaller but still very clean session. Don’t sleep on Tuesday the 11th either, that glassy afternoon is going to be magic.

Rusty out.

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.
