The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Ribanceira over the next couple of weeks.

Right off the bat, it’s a rough start. The first few days are a write-off – tiny, weak swell and onshore winds, just nothin’ worth paddling out for. You’re lookin’ at a blank run from the start of the period all the way through to the 3rd of August. Don’t bother.

Things finally start to show a pulse on the 4th of August Tuesday morning. We’ve got a small but clean 3 ft southerly swell, period around 12 seconds – that’s some real groundswell energy. The wind is glassy, dead calm. The wave energy is moderate at best (261), but it’ll be a fun little session for the intermediate crew. It’s a sandbar setup, fairly consistent, and it’s sheltered from the south, so it catches that S swell nicely. Water temp is about average for the time of year at 67°. The afternoon stays clean with cross-off winds and a touch more size at 3 ft.

The 5th of August Wednesday morning is worth a mention too – glassy again with 3 ft from the SSE, moderate energy (145). It’s not gonna blow your mind, but it’s clean and rideable.

Now, here’s where it gets interesting. The real standout is the 12th of August Wednesday. That’s the one you want to circle on the calendar. Morning brings a solid 7 ft southerly swell with a 11-second period, very strong energy (1993), and clean cross-off winds. That’s big, powerful, and well-shaped. By the afternoon, it jumps to 8 ft from the south, 12-second period, and the energy is through the roof (3025). This is excellent, heavy surf – strictly for experienced surfers only. It’s too big for beginners. The swell direction matches the optimum S direction for the break. This is the best on offer for the whole window.

The 11th of August Tuesday morning is also a good one – 6 ft S swell, 10-second period, clean offshore winds, strong energy (647). That’s a solid, clean day for the intermediates.

Later in the second week, the 15th of August Saturday morning is a nice surprise. 6 ft S swell, 12-second period, glassy calm. That’s a big, clean, beautiful day with very strong energy (1031). Promising, but it’s a ways out so keep an eye on it.

A quick heads-up: the swell on the 13th and 14th of August gets big, over 8 ft, but the wind turns cross-onshore and choppy, so it’s messy and only for the experts. For the rest of the period, it drops off again.

So, to sum it up: the first week is mostly a slow grind, but the 12th of August Wednesday is your absolute best bet – big, clean, powerful southerly groundswell. The 11th Tuesday and 15th Saturday are also solid. Get on it.

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.
