The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Ferrugem.
Alright, so we’ve got a bit of a mixed bag ahead. The week starts off pretty rough, with Friday and Saturday looking poor for a paddle. Friday morning sees a weak 3ft swell from the ENE with a short 8-second period and a cross-on southeasterly wind, making for choppy, messy conditions. The combined energy is weak at 126. Afternoon picks up to 6ft but the same cross-on wind and a southerly direction just keep things ugly. Saturday morning sizes up to 7ft from the SSE with a long 14-second period – that’s groundswell, and the energy jumps to 1574, which is strong. The wind is a cross-off from the north, so it’s clean, but the report says marginal surf or tricky tide. The swell is over 5ft, so it’s getting a bit much for beginners, and that long period means it might be a bit straight for the sandbar setup here. Saturday afternoon stays similar.
Sunday is a write-off: onshore winds and a messy S swell, 6ft to 8ft, with cross-on wind and poor conditions. Monday and Tuesday morning are still marginal, with cross-shore winds and moderate energy around 944 to 707. Not worth rushing out.
The standout window starts Tuesday afternoon, 11th August. The wind drops to glassy – zero wind – and you’ve got a 5ft swell from the SSE with a 12-second period, giving moderate energy (756). The report says “expect very good surf conditions.” This is the pick of the first week. Clean, glassy, fun waves. It’s intermediate-friendly at that size, but the period is long enough to give some punch.
Wednesday morning, 12th August, is another highlight. Swell bumps to 6ft from the SSE, 12-second period, strong energy (1030), and a light cross-off north-northeast breeze keeping it clean. The report calls it “excellent for experienced surfers” – that 6ft is getting up there, so it’s probably handling better for the more skilled crew. Wednesday afternoon stays clean but smaller at 5ft.
Thursday morning, 13th August, is glassy again, with a 5ft SSE swell and 12-second period. Energy is 974, strong, and the report says “very good.” This is a solid, clean session.
We then hit a bit of a dry spell. Friday and Saturday (14th-15th) see onshore or cross-shore winds and a drop in quality, with the swell hanging around 6ft to 4ft but the wind angles turning poor. Sunday morning, 16th August, offers a clean 6ft from the E with a short 7-second period – that’s windswell, but the cross-off wind keeps it rideable, and energy is moderate (701). The report says “very good.” Short period, so it’ll be a bit lumpy, but clean.
The second week picks up again. Tuesday, 18th August, is the next real standout. Morning swell is 5ft from the ENE, short 7-second period, but a clean cross-off wind gives it a “good” rating. Energy is light at 270. But the afternoon gets glassy – zero wind – with the same 5ft ENE swell, now 8-second period, and energy at 314. That’s clean, glassy, and fun. Best of the second week.
Wednesday 19th is clean again but smaller at 5ft to 4ft. Thursday morning, 20th August, is glassy again with a 4ft SE swell, long 12-second period, and moderate energy (560). The report says “very good.” That’s a sneaky good session for the longboard or a fun shortboard.
Friday afternoon, 21st August, goes glassy and clean with a 4ft SE swell, 12-second period, and energy 532 – “very good” again.
The water temperature anomaly isn’t given, so no comment on that.
Best on offer: Tuesday afternoon, 11th August (5ft, SSE, glassy, 12s) and Thursday afternoon, 18th August (5ft, ENE, glassy, 8s). The Tuesday session is the top pick for quality and conditions. The Thursday session is a close second.
Keep in mind, Ferrugem is a sandbar so it can shift, but with these clean winds and decent groundswell, it should be good. Crowds are “often” here, so expect company.

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.
