The Lowdown
Alright, surfers, Rusty here. Let's get into what’s comin’ down the pipe.
Alright, so right off the bat, Wednesday the 5th is a bit of a pooch. There’s surf, but honestly, it’s pretty ordinary with a light rain and a cross-off breeze. Not one to get excited about yet.
Things start looking up on Thursday morning, the 6th. We’ve got a tiny 2ft swell from the SSE, but the wind is glassy. Absolutely dead calm. For a spot like Ferrugem, a sandbar break, that’s a rare treat and the cleanest it’ll be all week. The wave energy is weak, just 107, so don't expect power, but for a longboard or a groveler, that morning session will feel like a private lake.
The rest of the week is a bit of a write-off, honestly. Friday through Sunday, the wind gets ugly, swinging cross-on and onshore, chopping everything up. There’s a bit of size, with a 6ft S swell on Friday afternoon rocking some moderate energy (435), and a bigger 6ft to 7ft SSE groundswell showing up Saturday with a long 14-second period and serious energy (1885), but the wind just ruins it.
Now, let’s talk about the standout. That Saturday the 8th session is the one I’d circle. The morning has 7ft of SSE groundswell with a 14-second period. That’s a proper groundswell with a huge 1885 combined energy reading. The wind is a clean cross-off from the NNE, keeping the faces tidy. This is a high-performance wave, but keep in mind, 7ft is solid. It’s getting into that expert-only territory, especially on a sandbar. The long period means the sets will be powerful and a bit more walled up, but the offshores should keep it from closing out completely. Crowds could be a factor – it’s _Ferrugem_, and anytime it’s good, it gets busy, so be prepared for that.
Sunday morning (the 9th) the wind shifts back onshore, so don’t sleep through Saturday.
Glancing further ahead, we get another short window on Thursday the 13th. The morning has a 4ft SSE swell with a gentle cross-off, but the real winner is Thursday afternoon. We get glassy conditions again, with a slight 5ft SSE groundswell and a combined energy of 615. It’s not huge, but that glassy surface will make it feel much better than the size suggests.
The following weekend into the new week gets bigger but messier. Saturday the 15th has a big lump of 8ft ESE windswell (period of only 8 seconds), which is a bumpy mess with onshore winds – that looks more like a kite-surfing day than a paddle day. Sunday the 16th is the same story, with 8ft of E swell but a howling 30 km/h cross-off from the NNE. It’s clean but raw and powerful (2298 energy), definitely a day for the experienced crew only.
The last real highlight is Monday the 17th afternoon. The swell drops to a more manageable 8ft from the E, but the wind stays clean cross-off and the energy is still a robust 916. The forecast says "very good surf conditions" for that session. And then we bookend it with Tuesday the 18th afternoon – another glassy session, this time with a 6ft E swell and a 10-second period. That combination of glass and 6ft of E swell will be a fantastic way to finish the run.
So, to boil it down: Get after Thursday morning the 6th for the glass, but the real standout is Saturday morning the 8th for the size and power. The second best is Tuesday afternoon the 18th for the glassy finish.
Stay stoked, and I’ll see you out there.

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.
