The Lowdown
Alright, Rusty here, checkin' in from the beach. Let's get straight into what the ocean's got cookin' for us over the next couple of weeks.
Overall, it’s a bit of a mixed bag to start. The first week is going to be a real struggle with messy, onshore conditions and a lot of choppy water. We've got a real standout window tucked away in the second week though, so don't lose hope.
Thursday the 10th is actually a bit of a tease. The morning at Ferrugem is looking glassy, with a clean 3 ft S swell, a period of 12 seconds, and moderate wave energy (449). That's the kind of start that gets your hopes up. The water is sitting at 62°F, which is a solid 4°F colder than normal for this time of year, so you'll want a good thick wetsuit. The afternoon stays small at 3 ft from the SSE, but the wind turns cross-on and it gets a bit messy.
Then the wheels fall off a bit. Friday the 11th brings rain and a short period, weak 5 ft swell from the NE. By Saturday the 12th, the swell jumps to a powerful 8 ft from the S with a combined energy of 1521, but a strong 16 mph cross-shore wind is going to chop it up something fierce – that’s a kite-surfing setup, not a paddle-surfing one. The rest of the first week (through to around the 17th) is a write-off: onshore winds, rain, and generally poor conditions. It’s a long, frustrating gap with nothing worth paddling out for.
Now, let's talk about the real deal. Friday the 18th of September is where it gets interesting. After all that mess, we get a clean 4 ft SSE groundswell rolling in with a 12-second period. The wind is a crisp cross-offshore breeze from the N at 9 mph, leaving the waves tidy. The combined energy is solid at 711. This is the standout of the whole outlook.
But the true gem is Saturday the 19th of September. The wind drops right out for a glassy morning session. A long-period SSE swell of 14 seconds wraps in at 3 ft, and that combination of total glass and quality groundswell is going to turn Ferrugem into a beautiful, lined-up sandbar. The wave energy is still decent at 537. For a sandbar break, that very long period (over 15 seconds) can make it break a bit straight, but with the glassy conditions, it'll be well worth a look. This is your session. Mark it on the calendar.
After that, the momentum fades. Sunday the 20th stays clean with the same cross-off wind, but the swell drops to a weaker 4 ft from the E. The last few days of the outlook (the 21st through the 25th) are back to poor, small, and onshore again, finishing off with a tiny 1 ft swell.
So, to sum it up: a couple of decent, clean windows early on the 10th and a big, beautiful payoff on the 18th and 19th. The rest of the time, you might be better off cleaning the wax off your board at home.
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.
