The Lowdown
Alright, let’s look at what’s cooking at Ferrugem.
We’ve got a quiet start. Don’t bother getting the board wet for the first few days – the surf is poor. There’s a gap of a couple of days with nothing to get excited about.
Saturday, August 22, things start to wake up. There’s a decent S swell at 8ft and 9 seconds in the morning, with combined wave energy of 1629 (moderate to strong). That’s good energy, but the wind is cross-shore from the SW at 9 mph. It’s not perfect, but it’s rideable for the experienced. This is a standout – the biggest push of the period, and Ferrugem is an exposed sandbar that can take it. However, at this size, it’s not a friendly day for beginners.
The real standout is Monday, August 24. Early morning, we’re looking at a solid 8ft swell from the SSE with a very long period of 16 seconds – true groundswell. Combined energy is a heavy 3293 (strong). The wind is light and cross-shore from the SW at just 6 mph, leaving the surface pretty clean. That’s the one: powerful, long-period swell for the more experienced surfer. Just remember, with such long period, it can get a bit straight at beach breaks, but Ferrugem’s sandbar might still give you some decent walls.
Later in the week, the mornings of the 27th and 28th also look good. Friday the 28th is glassy with a 6ft ENE swell at 8 seconds, and combined energy of 499 (moderate). Clean and glassy – that’s a nice, relaxed session for those who don’t want the big stuff.
Water temp is about 67°F, which is pretty standard for this time of year. No need for a thick wetsuit.
A couple of mornings in early September could also deliver if the forecasts stick, especially the 3rd with glassy conditions and a 6ft NE swell. But that’s far out and less reliable.
Overall, expect moderate to strong energy on the weekend and early next week, with the best conditions on Monday morning. Crowds are “often” at Ferrugem, so you won’t be alone on the good days.

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.
