The Lowdown

Alright folks, Rusty here. Let’s have a look at what Ribanceira’s got cookin’ for us over the next couple of weeks. It’s a bit of a slow burn to start, but there’s some real juice lined up if you’re patient.

The first week is a mixed bag. We kick off Sunday the 6th with a solid pulse of 8 ft southerly swell, but that 25 km/h SW wind is straight offshore. That’s clean, yeah, but it's a bit of a battle to get out. The combined energy’s chunky at 831 (moderate wave energy) and the period is only 8 seconds, so it’s a bit weak and choppy. By Sunday afternoon, the swell bumps up to 10 ft from the south with 1478 energy (moderate), but the wind swings cross-offshore and it gets messy – a real grinder for experienced cats only.

Monday the 7th morning cleans up with lighter 10 km/h cross-offshore winds and a cleaner 6 ft south swell, 10-second period and 551 energy (moderate). That’s a much nicer, workable wave. But then the onshores kill it for a few days. Tuesday the 8th is a write-off with NE winds. Wednesday the 9th morning is a beauty though – glassy, 4 ft south swell with a long 12-second period pushing 415 energy (moderate). That little window is a gem for the sandbar.

Thursday the 10th morning is also dead glassy, but the swell drops to 2 ft. The period is a very long 16 seconds with 434 energy (moderate), so those sets will be fat and slow – best for a longboard or a point break kind of setup, not so much for a quick beachie. After that, we hit a dry spell. Friday the 11th through to Saturday the 12th morning is tiny and onshore – absolute flat spell for nearly two days.

The Standout

The real standout is the Ribanceira sandbar on Tuesday the 15th. The morning session kicks off with a clean 7 ft swell from the SSW, a short 8-second period, but 1278 energy (strong). The wind is a clean 15 km/h cross-offshore. It’s got punch and shape. The afternoon holds at 7 ft from the south, goes fully offshore with 15 km/h winds, and 877 energy (moderate) – that’s a solid, rippable afternoon. If you can only pick one day, Tuesday the 15th is the one.

The Long-Range Glimmer

Look ahead to Wednesday the 16th morning – glassy again, 6 ft from the SSE with 597 energy (moderate). Clean and fun. Then Friday the 18th morning and afternoon both show a decent 5 ft to 5 ft south swell with a long 12-second period, clean offshore winds, and 842 energy (moderate). That’s a promising little window for a late-week paddle, but it’s a long way out, so keep an eye on it.

The Other Stuff

The water temperature anomaly isn’t given here on this first day, so we’ll just call it average for the time of year for our first mention of Ribanceira. Crowds are listed as “sometimes” here, so you might have a few locals out on the good days, but nothing mental.

Overall, forget the first week’s blowy bits. Hold out for Tuesday the 15th for the best quality, and keep the 18th in the back of your mind.

Rusty, signing off.

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.
