The Lowdown
Alright, Rusty here. Let's have a look at what's coming up for Ferrugem.
First up, the water temp is sitting at about 67°F, which is roughly 2°F warmer than usual for this time of year, so nothing too wild, just a touch on the mild side.
Honestly, the next week or so is pretty grim. We’ve got a long stretch of small, weak swell with poor conditions. The first few days, from Sunday the 2nd through to the end of the first week, are mostly a write-off. The swell is tiny, around 2ft to 4ft, with a short, weak period of 7-8 seconds coming from the ENE. The wind is mostly onshore or cross-shore, and the wave energy is pathetic, in the 100-140 range (139). You’re looking at about 6 days of this kind of slop. It’s just not worth paddling out for.
We finally see a shift on Tuesday the 4th. A new SSE swell pushes in with a solid 12-second period, and the energy jumps to 333. That’s a proper groundswell. The Tuesday morning session looks like the first real window of the whole forecast, with some clouds and a light NNE cross-offshore breeze at about 6 mph. The waves will be around 3ft, but that long period will make them punchy and clean. It's a short-lived window though, as the wind swings around by the afternoon.
The real standout, the one to circle on the calendar, is Tuesday the 11th of August. This is for the experienced crew. We’ve got a solid SSE swell rolling in with a 8ft to 8ft face, a very long 13-14 second period, and the wind is forecast to be glassy – zero to 3 mph from the SW and S. The wave energy is massive, hitting 1777 to 2219. This is powerful, clean groundswell. The longer period means it will barrel and hold its shape, but at this size, it’s strictly for the experts. The beach break setup could see it shutting down a bit, but for the right surfer, Tuesday the 11th is the best bet in the entire 16-day window. Keep in mind this is a long-range call, so it’s promising but not locked in yet.
The swell backs off again after that, but we get some moderate, cross-off conditions on the 15th and 16th with smaller 4ft to 5ft swell from the SSE and ENE, though the wind gets stronger, making it a bit of a battle.
So, to sum it up: a long, flat spell to start, a brief clean-up on the 4th, and then a big, heavy, glassy session for the experts on the 11th. That's your best shot.

Information about the Ferrugem Surf forecast
The above surf forecast table for Ferrugem provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ferrugem can be found by selecting the local surf guide option on the grey menu. Our Ferrugem 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 (Ferrugem) 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 Ferrugem 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.
Ferrugem is 18 km (11 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.
