The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for Ribanceira over the next couple of weeks.

Right now, things are looking pretty grim. We've got a long, quiet run to start. Monday afternoon is flat with a messy onshore breeze, and Tuesday is even smaller. We're talking waves you'd struggle to stand up on. The water temp is sitting right on the seasonal average at 65°, so no surprises there.

Wednesday and Thursday don't get any better either, with tiny swell and the wrong wind directions. Friday morning looks glassy but still barely a ripple. Then Friday afternoon, we finally see a pulse of real swell – a 6ft south swell with a clean offshore wind. The combined energy is still moderate (377), but it's surfable. Saturday morning keeps that going with a 5ft south swell and gentle offshore wind, clean and rideable.

But the standout – the one you've been waiting for – hits on Sunday the 23rd. That morning, we've got a 8ft south swell with a 10-second period and light offshore wind. The combined energy is strong at (2549). That's excellent surf for experienced surfers, no doubt. It's big and powerful. The wind stays clean through the afternoon, though the swell drops a touch to 8ft. For most, that's the pick of the whole forecast.

Monday the 24th also delivers. A 6ft south swell in the morning with offshore wind, and the afternoon sees a 8ft south swell with a long 14-second period and light cross-offshore breeze. The energy is very strong (2068) – excellent conditions again, but that long period will make it a bit straight at the sandbar, so better for a point or reef.

After that, the quality fades quickly. Tuesday the 25th is messy with onshore winds, and the rest of the week drops off into smaller, choppier waves. A few glassy mornings return, like Thursday the 27th, but the swell is tiny. By the end of the month and into September, it's mostly flat or weak and wind-affected.

So, the bottom line: if you're an experienced surfer, clear your schedule for Sunday the 23rd and Monday the 24th. That's where the magic is. The rest is a waiting game.

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.
