The Lowdown
Alright, Rusty here, checking in on the local waves.
Alright, it’s been a bit of a slow start here at Ferrugem, with the last few days of the week looking pretty average and only a few windows where it’s worth paddling out. For a spot that's usually very consistent, we’ve got a bit of a lull on the cards, especially early on. Things start to pick up in the second week, with one absolute standout session looking like the best bet by a long shot.
For the first few days, from Thursday the 3rd through the weekend, it’s mostly a write-off. There’s some small, short-period swell around, but winds are mostly cross or cross-onshore, making for choppy, poor conditions. There’s a bit of a bump on Saturday morning, with a 4 ft S swell, but it’s crossed up and messy. The standout window doesn't start to appear until next week.
The real magic window opens up on Monday, September the 14th afternoon. This is the best bet. We’ve got a clean, glassy 4 ft swell from the SSE, but here’s the kicker: the period is 13 seconds and the combined energy is pushing strong at 1101. That’s proper long-period groundswell energy. The wind is glassy (less than 5 km/h from NNE), so it’s going to be clean as a whistle. This wave will break with fantastic shape and lots of power. The water temp is about average for this time of year, so just a standard springsuit or shorty. The crowds can be a thing here, and with quality like this, expect plenty of company. This is for experienced surfers, as the long period will create some serious welter.
Then, the following day on Tuesday the 15th is a bit more mixed, but the Wednesday the 16th morning is another glass-off gem. The wind is calm, absolutely zero, and the swell is a nice, clean 5 ft from the south. The combined energy is moderate at 525. The period is a shorter 9 seconds though, so it's more of a fun, rippable windswell than the grinding groundswell from Monday. It’ll be clean, so it’s a good option for intermediates who want some playful waves.
As we head into Thursday the 17th afternoon, we get another shot of glassy conditions. The south swell is 5 ft with a 10-second period, combined energy at 516, and winds dropping to a glassy 3 mph. This will be another very good session, clean and consistent, with good shape for the lineup.
Finally, on Friday the 18th morning, a clean, cross-offshore breeze from the north cleans up a 4 ft south swell. It’s a smaller day but with good conditions for a fun session before the wind kicks up.
So, to wrap it up, the standout is that Monday the 14th afternoon – glassy, long-period SSE groundswell. That’s the one to circle. The rest of the ten days offers a few more clean windows, but that’s the cream of the crop. The first few days are a flat-out miss, so don't bother until Monday.
Stay stoked,
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.
