The Lowdown
Alright, let’s get into it. This is Rusty, and I’m lookin’ straight at the Ferrugem stretch for the next couple of weeks.
We’ve got a bit of a slow start, but don’t let that fool ya. The first real surf worth paddling out for hits on the morning of Saturday the 25th of July. It’s a clean 5 ft swell from the SE, with a period of 9 seconds, and the water’s sitting at a comfortable 66°F, which is about normal for this time of year. The wind’s a light NNW cross-off, so the waves should be holding shape nicely. The combined energy sits at 372 (moderate), so there’s a bit of push behind it. The break is a sandbar, very consistent, and it’s exposed to the swell, so it’ll be picking up that SE energy as intended. Crowds are often a thing here, so expect company.
Moving into Sunday the 26th, the swell drops off to 3 ft in the morning, still clean with a cross-off N wind, but the size is a lot more modest. The period stretches to 12 seconds, which is a proper groundswell, but it’s a small one. The energy drops to 377 (moderate). By afternoon, the swell gets even smaller and the wind picks up, so it’s not a standout.
Monday the 27th morning is glassy—dead calm, 3 ft from the ESE, but the period is a short 8 seconds, so the waves might be a bit weak and crumbly. Energy’s low at 164. Not a ripper.
From there, we run into a dry spell. Tuesday the 28th through Thursday the 30th are all small, messy, or just weak. We’re looking at waves around 1 ft to 2 ft, with poor conditions and low energy. It’s a gap of a few days where you’re better off doing something else.
Now, Friday the 31st of July morning looks like a solid return. The swell bumps back up to 4 ft from the SSE, 12-second period, and a clean cross-off NNE wind at 9 mph. The energy jumps to 401 (moderate), and it’s graded as good surf. That’s a nice little window to start the weekend.
The absolute standout, though, is the morning of Wednesday the 5th of August. This is the one to circle. The swell hits 5 ft from the E, with a period of 8 seconds, but the wind is dead calm—glass. That’s a rare treat. The wave energy is strong at 549, and the conditions are flagged as very good. This is the best on offer, no question. It’s a clean, punchy setup for intermediate surfers, though the 5 ft height might be a touch much for absolute beginners. Crowds will be likely, but the glassy conditions make it worth the squeeze.
Looking further out, the afternoon of Sunday the 9th of August brings another very good window. Swell builds to 5 ft from the NE, period 8 seconds, and a cross-off wind. The energy is strong at 565. This is a promising one, but it’s over two weeks out, so treat it as a hopeful call—forecasts can shift.
So, bottom line: the best surf is the morning of the 5th of August with glassy conditions and a solid 5 ft of E swell. The morning of the 31st of July is a solid runner-up, and the 9th of August could be a banger if it holds.
Stay sharp, and I’ll catch ya in the water.

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.
