The Lowdown

Alright, Rusty here. Let’s talk about Ribanceira for the next couple of weeks. The water’s sitting at 66°, which is pretty much spot on average for this time of year. No surprises there.

We’ve got a bit of a slow start, to be honest. Thursday the 3rd is a write-off – onshore wind and poor conditions. Friday the 4th morning shows a bit of hope with a clean, gentle offshore wind and a small 2ft SE swell, but the wave energy is weak (106) and it’s pretty ordinary. Saturday and Sunday the 5th and 6th pick up a little, with clean offshore winds and the swell building to 5ft on Sunday morning, but still just surfable, nothing special. The combined swell energy is moderate (289). Sunday afternoon gets a bit rowdy with 8ft and strong energy (880), but that’s getting too big for the average surfer and the wind goes cross-off, so it’s a bit of a handful.

Now, Monday the 7th is where it starts to get interesting. Monday morning has a 7ft SSE groundswell (10 second period) with a gentle offshore wind from the WSW. The wave energy is strong (844) and the conditions are clean. This is shaping up to be one of the better windows – decent size, good wind, and it’s a sandbar break that can handle that. Monday afternoon drops to 6ft with light cross-off wind, still clean and fun.

We hit a flat spell from Tuesday the 8th through to Thursday the 10th. Onshore winds and tiny swell, with energy dropping to just 36. Not worth paddling out.

Things start to look up again on Friday the 11th with a 6ft E swell showing up in the morning, but the wind is onshore and it’s not clean. That one’s a miss.

Saturday the 12th is totally flat – forget it.

Then we get a bit of a wildcard on Sunday the 13th: 4ft E swell with a moderate offshore wind, clean, but the period is short at 9 seconds. It’s surfable, but ordinary. The standout, though, comes on Monday the 14th. Monday morning has a 3ft S groundswell with a 13-second period, gentle offshore wind from the SW, and clean conditions. The combined energy is strong (607). That’s a classic groundswell – long period, good shape, clean. This is the pick of the two-week window for me. After that, it fades into small, clean but weak surf through to the 18th, with nothing else really firing.

So, the one to circle on the calendar is Monday the 14th for that S groundswell with clean offshore wind. Monday the 7th is a solid runner-up if you want a bit more size.

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.
