The Lowdown

Alright, let's get into it. The next couple of weeks at Ribanceira are a bit of a slow burn, but there's a massive payoff coming if you're patient. The first week is mostly small, messy, or blown out, but hang tight because the second week brings some serious size and power.

We start off with just about nothing. Sunday the 30th is flat with a tiny 0.7ft swell from the SSE and poor surf. Monday the 31st is a write-off too – heavy rain and onshore winds making a mess of the 8ft swell. It's not until Tuesday the 1st of September that we get a bit of a glimpse. The morning is glassy with a clean 6ft swell from the ESE. It's not huge, but it's rideable and the conditions are right. That's a small window though, as the afternoon turns stormy.

Wednesday the 2nd morning is the first real highlight in this first week. A solid 5ft swell from the SE, but what makes it is the strong offshore wind from the SW and the wave energy is pumping at 670 (moderate). That's clean, offshore, and fun. The afternoon gets bigger at 7ft, but the wind shifts cross-offshore, knocking the quality down a notch.

The rest of the first week is a bit of a mixed bag. Thursday the 3rd and Friday the 4th are small and ordinary, with the best being Friday morning's glassy 3ft SE swell. Saturday the 5th afternoon is worth a mention – a 6ft S swell with a gentle offshore wind, giving you clean, lined-up waves with moderate energy (470).

Now, here's the big one. The standout is Sunday the 6th of September morning. We're talking a 10ft S swell with a 11-second period, strong offshore winds from the SW, and the combined swell energy is a massive 2474 (very strong). This is expert territory – over 8ft and powerful. It's going to be clean, raw, and only for those who know what they're doing. The afternoon gets even bigger at 12ft, but the wind turns cross-off, so the morning is the pick.

Monday the 7th is an absolute monster. The morning holds 12ft S swell, with a light cross-offshore wind and a 14-second period, energy at 4467 (very strong). The afternoon is the absolute peak of the forecast: 12ft from the SSE, a massive 16-second period, and the energy hits 6008 (very strong). This is a rare, long-period groundswell. For a beach break like Ribanceira, that long period can make it a bit too straight, but the size and power will be incredible. This is definitely for experienced surfers only.

The rest of the second week is a letdown after that peak. Tuesday the 8th and Wednesday the 9th are onshore and messy, with the swell dropping from 10ft to 5ft. Thursday the 10th and Friday the 11th are poor with cross-onshore winds. There's a tiny window on Saturday the 12th afternoon with a glassy 5ft easterly swell, but it's ordinary.

The final weekend, Sunday the 13th and Monday the 14th, sees another big pulse of swell, 10ft to 12ft from the east, but the wind is cross-onshore or onshore, so it's a messy, blown-out mess. The energy is high (over 2000), but it's not a paddle-friendly setup. Honestly, for those days, it looks more interesting for kite surfing than paddle surfing.

The water temp is about average for the time of year, nothing unusual.

So, there you have it. The early days are a grind, but that Sunday the 6th and Monday the 7th are the real deal. Don't miss it.

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.
