The Lowdown

Alright, Rusty here, let's look at what's on the menu for our local break, Ferrugem.

First up, I gotta be straight with you – the next few days are pretty flat. We’re looking at a real slow start. From the 30th of July all the way through to the 2nd of August, there’s just nothing worth paddling out for. It’s a proper dead spell. The water temp is sitting about average for this time of year at 66°, so that’s not the issue.

Now, we finally get a little flicker of life on the morning of Monday the 3rd of August. We’re looking at a clean, 4ft swell from the NE with a short period of 7 seconds. The wind is light and cross-offshore, so the surface will be clean. The combined energy is moderate at 318, but honestly, it’s a short-period swell, so it’s not going to have much push. It’s surfable, but nothing to get stoked about.

Things stay pretty ordinary for a few days. Tuesday the 4th and Wednesday the 5th offer some small, knee-to-waist high waves. The best of that patch is Wednesday morning the 5th of August – it’s only 2ft from the SSE with a 10-second period, but the wind is glassy and the water is clean. That’s a good window for a longboard or a foamie, but it’s not a standout.

The real story, the one that’s got me a little fired up, is the second week. We’ve got a serious pulse of swell arriving on Monday the 10th of August. The afternoon session is looking primo: 3ft from the SSE, but with a long 14-second period pushing a hefty 615 units of energy. The wind is light and cross-offshore, so it’ll be clean. That’s a solid day for a point break or a reef, but at a sandbar like Ferrugem, don’t expect the world from a long-period swell.

But the absolute standout, the day you want to circle on the calendar, is Tuesday the 11th of August. We’re talking a solid 10ft groundswell from the S with a 10-second period in the morning. The combined energy is a massive 3418 – that’s some serious power. The wind is glassy, and the conditions are described as excellent for experienced surfers. This is a big, powerful swell. At over 8ft, this is for the crew who know what they’re doing. It’s going to be a heavy, challenging day, but for the experts, it’s the best on offer. The afternoon drops to 8ft, still glassy, still a lot of grunt.

The 12th and 13th of August keep the energy high, but the wind gets a bit messy. The 13th of August morning has an 12ft swell from the SE, but it’s flagged as too big for this break. The afternoon of the 13th, though, with 8ft from the ESE and glassy wind, is another excellent window for the experienced crew.

To wrap it up: the first week is a write-off. The second week delivers the goods. The absolute best day for a proper surfer is Tuesday the 11th of August, with the morning being the pick of the pick for big, powerful, clean waves. Get your board waxed for that one.

Rusty.

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.
