The Lowdown
Alright, Rusty here. Let's have a look at what Ferrugem has in store for us.
Right off the bat, we’ve got a solid stretch of Southern Ocean groundswell rolling in, and the water is sitting at 67°, which is pretty much bang on average for this time of year. The consistency here is usually very good, so you know there’s always something to work with.
The pick of the entire outlook is going to be Tuesday morning, August 11th. We’ve got a clean 7ft swell pushing in from the SSE with a long 12-second period, and the wind is practically dead – glassy. That’s about as good as it gets for an intermediate-level crew. The wave energy is strong at 1140 (moderate to strong), meaning there’s plenty of push behind those lines. This one is for the experienced surfers, as it's a bit too big for beginners.
Wednesday the 12th is also a good call. Both morning and afternoon see a clean 5ft to 6ft SSE swell with light offshore winds from the North. The energy is still decent (931 and 711), so you’ll get some nice, lined-up sandbar waves.
Friday the 14th is another standout with two glassy sessions. The swell drops a touch to 6ft from the SSE, but that long 13-second period keeps things punchy and well-shaped. Energy is strong at over 1200. Again, this is beefy enough to be for experienced surfers only.
The next few days after that drop off in size and energy. The swell shrinks down to around 3ft to 4ft over the weekend of the 15th and 16th, and the period shortens to 8 seconds. It becomes a bit weak – combined energy drops to between 207 and 477 (low to moderate) – and a bit messy. Not really worth getting wet for.
Then we hit a rough patch from Monday the 18th through to Saturday the 22nd. We get strong onshore winds from the SSW and S, whipping up lumpy, choppy conditions. The swell stays small and the period is short. This is messy, junky stuff – honestly, this setup looks more interesting for kite surfing than paddle surfing.
The week after shows a glimmer of hope. Monday the 24th afternoon brings a bigger pulse of SSE swell back in at 6ft with a long 13-second period. The wind is cross-off, keeping things clean. The energy is strong at 1204. This is a solid session.
And the final real highlight is Tuesday morning, August 25th. We get another excellent session with a clean 5ft S swell, a long 13-second period, and light offshore winds. Energy is very strong at 1419. Perfect for experienced surfers looking to score some proper lines on the sandbar. Just be aware that crowds are often here, so get out early.
So, the long and short of it: jump on Tuesday the 11th, Friday the 14th, Monday the 24th afternoon, and Tuesday the 25th morning. The rest is either too small, too wind-affected, or a complete write-off.
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.
