The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for us. We’ve got a solid 16-day window to work with, but it’s gonna be a bit of a slow burner this time. There’s a few days of nothing much before things start to turn on, so don’t rush out there just yet.
The opening few days are a write-off. Nothing worth paddling out for until things start to shape up on Thursday the 17th. That’s when we get our first real taste.
Thursday the 17th is your first proper standout. Morning session at Ferrugem is looking clean. We’ve got a 5ft SSE swell running with a nice 11-second period – that’s proper groundswell energy, giving the waves some good shape and grunt. The wind is a light NNE cross-offshore, so the faces will be clean. The combined energy is decent at (551), so there’s plenty of push. If you can get out there, it’ll be worth it. The water temp is sitting around 62°, which is a couple of degrees cooler than usual for this time of year, so a bit nippy – don’t forget a decent wetsuit.
Friday the 18th isn’t as punchy, with the swell dropping to around 3ft, but it’s still clean both morning and afternoon with a nice cross-off breeze. A good option for a quieter, smaller board.
Things get a bit messy over the weekend with some rain and cross-shore winds, but the energy builds. Then we get to Sunday the 21st of September. This is the other real standout of the whole run. Monday morning, the 21st, is looking absolutely magic. The swell picks up to a solid 6ft from the ENE, with a 9-second period. The wind goes completely glassy (0 mph). That’s as good as it gets. The water will be like a mirror. This is quality for a solid intermediate session. The combined energy is strong at (635), so expect some fun, punchy walls. Get on it.
After that, the swell settles down again. There are some cleaner, smaller mornings around the 22nd and 24th of September, but nothing that will blow your hair back. The very end of the forecast, on Tuesday the 29th of September, we get another glassy morning with a waist-high 5ft SSE swell. It’s a good, clean option to close out the run.
Overall, keep your eyes on Thursday the 17th morning and especially that glassy Monday the 21st. That’s where the gold is.
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.
