The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' at Ferrugem for the next couple of weeks.
Right off the bat, I gotta be honest with you: the next few days look pretty grim. We're starting off with a lot of cross-shore wind and messy, chopped-out surf. Saturday the 12th is a write-off with a sloppy 5ft south swell, and Sunday the 13th isn't much better with poor conditions. There's a bit of a wait before things start to clean up.
The first real glimmer of hope comes Monday morning, the 14th of September. We get a clean, 3ft south groundswell with a nice 11-second period and a light cross-offshore breeze. The water's about 62° and feels much colder than normal for this time of year, so you'll want a thick wetsuit. It's not huge, but it'll be clean and rideable. The combined swell energy is moderate (350), so there's some push behind it.
Now, the standout window – and I mean the absolute *best* on offer in this whole stretch – is Thursday the 24th of September. Thursday morning is looking like an absolute gem. We've got a solid 6ft south swell, with a 10-second period and glassy conditions. That’s flat calm and glassy in the books, and you and I both know what that means: perfection. The combined energy is a strong 1363, so there's plenty of power. This one's a treat for experienced surfers; at 6ft it's gonna be a bit much for beginners. The Thursday afternoon isn't too shabby either, with a 4ft drop to a longer 11-second south swell, staying glassy.
Before that standout, there are a couple of other mornings worth paddling out for. Thursday the 17th of September morning has a clean 5ft south swell with an 11-second period and cross-offshore wind (combined energy 626). Monday the 21st of September morning is another clean one, with a 7ft east swell, but the 8-second period means it'll be a bit lumpier and more for the experienced crew at that size. And then the morning of Wednesday the 23rd looks like a sneaky little window with a 6ft south swell, but it's a bit of a wildcard with onshore wind.
As we roll into the second week, the pattern holds with clean morning windows if the wind plays nice. The 25th and 26th of September mornings show good 4-5ft south and SSE swells with longer periods (12-13 seconds) and cross-offshore winds. After that, it looks like we're back into a more mixed, onshore pattern toward the 27th.
The Bottom Line: The first few days are a frustrating wait, but if you can hold out, the morning of Thursday the 24th of September is the clear stand-out – glassy, solid south swell, and all the quality you could ask for. Monday the 21st morning and Thursday the 17th morning are also solid secondary calls.
Stay stoked, and keep an eye on that Thursday morning.
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.
