The Lowdown
G’day, Rusty here, dialin’ in from the local sandbar. We’ve got a bit of a mixed bag stretchin’ out over the next couple of weeks, but there’s a couple of windows that’ll get the blood pumpin’. Let’s break it down.
Right now, we’re sittin’ in a quiet spell. The first real chance to wet a line comes on Wednesday the 15th of July, but honestly, it’s a bit of a write-off. Ferrugem is showin’ a 4 ft ESE swell with a 10-second period, and cross-off winds from the NNE at 19 mph. The water’s 60°, which is a solid 6° colder than normal for this time of year, so you’ll want a thick wetsuit. The combined energy is weak (296), so it’s flat and poor. Thursday the 16th and Friday the 17th are more of the same—small, choppy, and not worth paddlin’ out for.
Now, Saturday the 18th of July starts to get interestin’. The swell bumps up to 7 ft from the NE, but it’s short-period at 8 seconds, so it’s a messy windswell. The combined energy hits moderate (1130), but with cross-off winds, it’s still just marginal. Sunday the 19th is similar with 7 ft NE swell and 900 energy. This is more for the experienced crew—over 8 ft and it’s expert-only, so keep that in mind. The water’s still cold, but nothin’ stand-out yet.
The standout in the first week? Monday the 20th of July afternoon. Ferrugem gets a clean 6 ft NE swell, with glassy offshore winds from the ESE at 3 mph. The combined energy is moderate (727), and that clean face will have some peelers. It’s a sandbar, so it’s consistent, but crowds can be likely here—it’s “often” busy. Still, for a Monday arvo session, you might snag a few empty ones.
The next few days are a bit of a lull. Tuesday the 21st morning has 5 ft NE swell and 534 energy, with light cross-off winds, but it’s just okay. From Wednesday the 22nd through to Friday the 24th, it’s small and messy—3 ft to 4 ft, weak energy, and poor wind. There’s a three-day gap of nothin’ worth mentionin’.
Then we hit the second week, and it gets tasty. Saturday the 25th of July morning brings a 6 ft S swell with 9-second period, combined energy of 963. Light cross-on winds, but it’s a solid, punchy wave. Sunday the 26th morning is the real gem: 5 ft SSE swell, 10-second period, light offshore winds from the N at 6 mph, and clean conditions. The energy is moderate (556), and it’s labeled as “very good.” That’s your session for the week.
But hold onto your board—Monday the 27th of July afternoon is the big one. A 8 ft SSE swell with a 15-second period, and combined energy of 2991—that’s strong energy. This is a long-period groundswell, so at a beach break like Ferrugem, it might break a bit too straight. It’s really better for a point or reef. With cross-off winds, it’s clean, but this is expert-only territory. Only the skilled crew should be out there.
Tuesday the 28th morning is still good with 6 ft SSE swell at 13 seconds, 979 energy, and light offshore winds. Wednesday the 29th morning and afternoon are both clean and glassy, with 5 ft and 5 ft SSE swell, 11 seconds, and light winds. Solid, fun waves. The last few days of the month, the 30th, fade out with small, choppy slop—3 ft to 3 ft, poor conditions.
So, the best on offer? Sunday the 26th of July morning for a clean, fun session, and Monday the 27th of July afternoon for the big swell, but only if you’re experienced. Crowds are likely at Ferrugem, so get there early. Stay stoked, and I’ll catch you in the lineup.

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.
