The Lowdown
G'day, Rusty here, checkin' in from the beach. We've got a bit of a mixed bag ahead for Ferrugem, but there's a couple of absolute ripper sessions on the horizon if you play your cards right.
The first real action kicks off on the morning of Sunday, the 23rd of August. We see a drop in the swell to 6 ft from the south, but it's a clean 11-second period. The real story here is the glassy conditions thanks to the SSW wind at just 3 mph. The water's sitting at 67 °F, which is about average for the time of year, nothing to write home about. The wave energy is solid at 762 (moderate). It’s a good warm-up, but not the highlight.
The standout session is the Monday morning of the 24th of August. The swell pumps up to 8 ft from the SSE, with a long 14-second period that’s got some serious grunt—the combined energy is a massive 2740 (very strong). That’s a proper groundswell, and it's going to be powerful. The wind is glassy again from the WSW at 3 mph. This is a punchy wave, so it's one for the experienced crew. The period is long, so it might be a bit too straight for the beach break, but the sandbar at Ferrugem should handle it better than most.
The Tuesday morning of the 25th of August is another solid option. The swell has eased to 6 ft from the SSE, but it's still a quality 13-second period. The wind is a light cross-off from the north at 6 mph, keeping things clean. The energy is 1009 (moderate), making for a really fun, manageable session.
The period from the 28th of August through to the 1st of September is a bit of a lull with smaller swells and mixed wind. The 30th of August has some glassy conditions on the Sunday morning, with a 5 ft easterly swell, but it's a bit weak. The 1st of September afternoon sees a return of glassy conditions with a 5 ft south swell, but the energy is low.
From the 2nd of September onwards, things get messy. The swell drops off and the wind turns onshore. By the 6th of September, the swell is building again with a 7 ft easterly swell, but it's a short 7-second period driven by a fresh NNE breeze at 16 mph, creating a messy, blown-out affair. That's more of a kite-surfing setup than a blissful paddle session.
So, to wrap it up: if you've got the experience, the Monday and Tuesday of the 24th and 25th of August are your best bets. The surf is clean, the swell is solid, and the energy is there. The rest of the run is a waiting game for the next proper pulse.
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.
