The Lowdown
Alright folks, Rusty here. Let’s get into it.
The next couple of weeks are a bit of a mixed bag for us, honestly. The early part of the outlook is pretty quiet, with some small, clean waves but nothing to get too excited about. The real action looks like it’s building towards the end of the first week and into the second week, with a couple of standout windows that could be worth clearing your schedule for.
We start off on Tuesday the 4th of August. The morning at Ferrugem has a small, clean 3-ft SSE swell pushing in with a solid 12-second period – that’s a nice groundswell. The wind is a light cross-offshore from the north, so it’ll be pretty clean. Combined wave energy is moderate (331). Water temp is sitting at 66.9°, which is about normal for this time of year. Not a day for a big swell, but for a quiet paddle, it’s a decent start. The afternoon gets a bit tricky with a risk of thunderstorms and a glassy cross-shore, but the surf is marginal.
Wednesday the 5th is smaller again, with 2.5-ft waves. The morning has glassy conditions with no wind at all, so it’ll be a mirror out there. The swell is a bit weak (165 combined energy), so it’s just a cruisy, small-wave session. The afternoon turns cross-shore and a bit messier.
Thursday the 6th and Friday the 7th are in the same boat: small, clean waves with the wind holding cross-offshore. Thursday has a short period 7-second ENE swell, so it’s not a lot of push. Friday morning sees a 3-ft ENE swell with a nice offshore wind, but the afternoon gets a bit of a cross-onshore breeze and a short period S swell, making it choppy.
Now, Saturday the 8th of August is where things start to shift. A solid 6-ft SSE groundswell rolls in for the morning, with a 12-second period. The wind is a clean cross-offshore from the north-northeast, so the waves will be looking good. The combined energy jumps to a strong 1205, so there’s some real power behind it. This is a proper size for experienced surfers, but it’s not out of control for a confident intermediate. The afternoon stays clean with a similar size, though the energy dips a little. This is the first real standout of the forecast.
Sunday the 9th is a bit of a step down, with 4-ft to 5.5-ft SSE swell, but the wind goes cross-shore and then cross-onshore, so it’s a fair bit messier. Not a write-off, but not the best.
Monday the 10th sees a bigger S swell, peaking at 6-ft in the afternoon with a long 13-second period. The wave energy is massive (1973). The wind is a cross-shore, so there’s a bit of chop on it, but the power is there. This one’s for the crew who don’t mind a bit of texture.
Tuesday the 11th is a proper standout. The morning is a bit messy with a cross-shore wind, but the afternoon at Ferrugem turns on. The wind swings to a cross-offshore from the southwest, and the 5-ft S swell has a nice 11-second period. The combined energy is still healthy at 621. The conditions come together for a really clean, fun session. This is the best of the first week.
Wednesday the 12th and Thursday the 13th are a mixed bag. Wednesday morning goes glassy with a 4-ft SSE swell, a great session for a quieter board. Thursday brings a bigger 5.5-ft swell, but the wind is side-shore, so it’s a bit bumpy.
Friday the 14th of August is a big one. The afternoon sees a glassy, 4.5-ft SSE swell with a 12-second period and a light north-northeast breeze. The wave energy is strong (1036). The conditions are described as excellent for experienced surfers, and I’d agree. The swell is solid, the period is long, and it’s glassy. That’s a rare combo. This is a top-tier session.
Saturday the 15th has a good morning with a 6.5-ft E swell and glassy conditions, but the period is a short 8 seconds, so it’s a bit crumbly. The afternoon gets a cross-shore wind that chops it up.
Sunday the 16th through Tuesday the 18th is a bit of a return to smaller, cleaner conditions. Not a lot of energy, but the wind is favourable for a clean ride.
Wednesday the 19th of August is the final big standout. The morning brings a solid 10-ft S swell, with a 9-second period and a strong cross-offshore wind from the north-northeast. The wave energy is massive (2314). This is an expert-only day. The swell is over 8-ft, so it’s big and powerful. The wind will keep it clean, but you need to know what you’re doing. The afternoon drops to 7-ft but the wind picks up to a fresh breeze, still cross-offshore.
So, to sum it up: the best windows

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.
