The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Ferrugem over the next couple of weeks.
We’re starting off a bit sluggish, but there’s a real standout waiting for us if we’re patient. The first few days are pretty average, with small, weak swell and only a brief window of clean conditions. The real magic looks like it’s building towards the end of the first week and into the second.
The water is running a touch warmer than normal for this time of year, sitting at 68°F.
Monday the 3rd is a write-off – small 3ft swell from the ENE with a short 7-second period and a cross-shore wind. Not worth paddling out for.
Tuesday the 4th is where things start to look promising. The morning session is the pick of the early days. We’ve got a glassy, clean surface and a 3ft SSE groundswell rolling in with a lovely 12-second period. The combined energy is moderate (323). The wind is virtually nothing, just a slight air from the north, making for some seriously clean lines. The swell bumps up to 3ft in the afternoon with a light cross-offshore breeze, so the afternoon is also looking good. This is a solid session for a sandbar, and the consistency is very consistent, so you won’t be waiting around. Crowds are likely, though.
Wednesday the 5th starts clean with a 3ft SSE swell (10 seconds), but it’s nothing special. The afternoon gets a bit messy with a cross-onshore wind, so better to get in early.
Thursday the 6th and Friday the 7th are rinse-and-repeat days with weak, short-period swell (8 seconds) and clean but ordinary conditions. The energy is low (158-197). Surfable, but you’ll be working for it.
Now, here’s the real headline. Saturday the 8th is the standout. This is the one to circle on the calendar. We’ve got a strong, long-period groundswell from the SSE, pushing 5ft in the morning with a very long 16-second period. The combined energy is massive (1462). This is powerful, quality swell. The wind is a light cross-offshore, keeping the surface clean. The afternoon stays just as good, with 5ft swell and a 15-second period. The energy is still very strong (1057). This is excellent surf for experienced surfers. The swell is a bit heavy for beginners, but for anyone with a bit of experience, this is going to be a proper session. This is a sandbar, and with a long-period swell like this, it might be a bit straight, but with the right tide, it’ll be world-class.
Sunday the 9th takes a step back. The swell drops, and the wind swings onshore and cross-shore, bringing chop. Not your day.
Monday the 10th through Wednesday the 12th are all marginal. The swell hangs around 4ft to 5ft, but the wind is either cross-shore or light cross-onshore, and the consistency is calling it “questionable tide conditions.” You could get a wave, but it’s nothing to get excited about. The energy is moderate (384-574).
Thursday the 13th offers a little reprieve. The morning has a clean, offshore wind from the NW with a 5ft NE swell. The period is short (6 seconds), so it’s a bit weak, but the glassy afternoon with 4ft from the ENE and a 7-second period is clean and easy. A good option for a mellow session.
Friday the 14th sees another size increase, but the wind is onshore. The 5ft SSE swell (12 seconds) in the morning has a lot of energy (1009), but it’s choppy. The afternoon gets bigger, up to 7ft, but it’s still onshore and messy. This one is for the experts only, and even then, it’s a battle.
Saturday the 15th is clean again in the morning with a 4ft S swell (11 seconds) and a light cross-offshore breeze. Good, solid, fun waves.
Sunday the 16th is a write-off with strong winds and small, weak swell.
Monday the 17th looks promising again. The afternoon has a 6ft swell from the east with an 8-second period, and the wind is a clean cross-offshore. The energy is moderate (484). Good, punchy waves for the sandbar.
Tuesday the 18th brings a big, stormy swell. The afternoon sees a 8ft SSW swell with an 11-second period, and the energy is through the roof (2145). This is a massive, powerful swell. The wind is a moderate cross-onshore, making it choppy and wild. This is for experts only, and honestly, with that wind and size, it might be more interesting for the kite surfers than paddle surfers.
Overall, the best bet is Saturday the 8th – that’s the session you don’t want to miss. The second-best window is the morning of Tuesday the 4th, and then Monday the 17th afternoon is a solid backup.
Stay wet, stay hungry.

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.
