The Lowdown
Righto, let’s have a look at what’s on the cards for Ferrugem.
The next week and a half is a mixed bag, with a few real windows of quality wedged between some pretty average spells. We kick off this Sunday the 19th with a bumpy 6ft NE windswell but a cross-off wind, so it’ll be a bit grotty and only worth a 2/10 – nothing to get excited about. Monday the 20th morning looks much better: glassy conditions and clean 6ft NE swell. That’ll be your best chance early on, but the afternoon gets crossed up.
Then we hit a quiet, messy stretch from Tuesday the 21st right through to Friday the 24th. Wave heights drop, winds get onshore or cross-shore, and the combined swell energy hangs around a weak 254 to 560 – not much push. Rain and poor conditions make it a bit of a write-off.
Saturday the 25th stays small with just 3ft SE swell but clean in the morning. Sunday the 26th has a glassy 2ft S swell (12-second period) which is super long-period and will be best on the point – but it’s small. The break’s a sandbar, so that long period might wall up straight at the beach.
Monday the 27th and Tuesday the 28th are tiny again, with long period south swell but barely a pulse, and the combined energy drops to a weak 148. Not worth the paddle. Wednesday the 29th is a write-off too.
Here’s where it gets interesting. We’ve got a total stand-out on Thursday the 30th morning: glassy conditions and a solid 7ft S swell. That’s a moderate energy reading (652), and the water temp is about average for July. This one’s got clean lines and good push, but at over 5ft it’s pushing the limits for beginners – better for your intermediate crew. It’s a very consistent spot (Ferrugem), and the swell direction is right out of the south, which matches the optimum SE direction on the sandbar, so expect some proper barrels if you’re on it. The morning will be glassy, so that’s a major plus.
After that, Friday morning the 31st has clean 5ft S swell with a 498 energy reading – not a standout, but a solid session.
Then we get the real highlight of the whole 16-day window. Saturday the 1st of August morning is absolutely firing: glassy calm, 6ft SSE groundswell with a very long 15-second period, and a massive combined energy reading of 1405. That’s strong, powerful swell. This one is excellent for experienced surfers. The long period means it’ll hold shape beautifully on this sandbar break, and the offshore wind (calm) will keep it glassy all morning. Expect clean 6ft faces, plenty of energy, and longer lulls between sets making the paddle out easier. Crowds are often around here, so get there early – it’ll be worth it.
Sunday the 2nd of August morning is almost as good: glassy, 6ft SSE groundswell with a 15-second period and 1420 energy. Another cracker, and still best for the experienced crew.
After that, Monday the 3rd sees the energy drop back to 846 with a smaller 4ft SSE swell and clean but moderate cross-off wind – still surfable but not a standout.
Bottom line: the real gold is on Thursday the 30th morning, but the absolute best is Saturday the 1st of August morning followed by Sunday the 2nd. Everything else is either small, messy, or just average. Don’t sleep on that first weekend of August – it’s going to be a ripper.

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.
