The Lowdown
Alright, Rusty here, lookin’ at what we’ve got on the cards for the next couple of weeks at Ferrugem.
We’re kicking off straight away. The first few days are looking alright, not epic but a solid start to the run. Tuesday the 8th, the morning’s the pick, clean little chest to head high waves with that 4ft from the SSE. Wind’s light out of the NNE, cross-off, so the face should be nice. Swell energy’s on the moderate side (354), but it’ll be fun. The water’s sitting at 64°, almost a full degree cooler than usual for this time of year, so you’ll feel that slight chill in the air.
Wednesday the 9th morning is where you want to be. Glassy conditions with a slight S breeze, and the swell holds at 4ft but from the ENE. The energy is solid moderate at 513, and that period is a short 8 seconds, so it’ll be a bit more crumbly and less pushy, but that clean surface makes up for it. You could get some really fun ones.
Now, things get a bit messy from late Friday the 12th into Monday. The swell builds – Saturday the 12th gets up to 7ft from the S but the wind is swinging onshore and it’s choppy. Not worth paddling out. Sunday the 13th has some solid 7ft SSE swell with healthy energy (1357), but cross-shore wind and questionable conditions mean it’s not firing. That’s a wait-and-see.
The real standout I’m watching is Sunday the 20th of September. That morning is shaping up to be a beauty – 10ft of NE groundswell, clean face with a light offshore breeze from the NW (10 km/h). Now, that’s a serious size, only for the experienced crew, but the energy is very strong (2104) and the wind is perfect. This one’s a promise at the moment, something to keep an eye on as it gets closer.
Then, to close things out, Tuesday the 22nd has a glassy afternoon session. Swell’s a bit smaller at 7ft from the SSE, but the period stretches out to a very long 14 seconds. That’s proper groundswell energy (1494), and with the wind dead flat, those waves will be peeling with real purpose. Perfect for a point or reef setup, but at a beach break that long period might make them a little straight, so pick your spot.
Overall, don’t get too excited about the middle of the run with the wind shifting. Hit the early mornings and definitely mark that Sunday the 20th and Tuesday the 22nd on the calendar.
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.
