The Lowdown
Alright, Rusty here. Let’s get into it for Ferrugem.
Right off the bat, Monday the 14th kicks things off, but the early part of the week is pretty average. The surf picks up nicely toward the middle of the week, with a couple of real standouts.
Tuesday the 15th morning is looking like the best on offer if you want clean conditions. The sun’s out, wind is glassy, and we’ve got a solid 6ft swell mixing in from the east-northeast with a period of 9 seconds. The wave energy is strong at (759), which means there’s some push behind it. The water feels pretty cold compared to normal, sitting at 62°F, which is a few degrees colder than usual for this time of year.
The next real highlight is Thursday the 17th morning. Glassy conditions again, with a 5ft swell from the south-southeast at 11 seconds. That’s a nice groundswell with longer gaps between sets, making it easier to get out the back. Wave energy is still solid (746). The swell direction lines up well with Ferrugem’s optimum from the southeast.
Thursday afternoon gets a bigger bump in size: 6ft from the south-southeast, and the period jumps to 14 seconds. The combined energy climbs to (1507) – that’s strong, powerful surf. Wind is cross-shore from the northeast at 12 mph, so it won’t be as clean as the morning, but the size and energy for the more experienced crew could be worth a look.
On Friday the 20th, the morning session cleans up with light cross-offshore breezes from the north-northeast. The swell drops to 5ft from the east, 8-second period, with moderate energy (276). It’s nothing special, but still good fun for a paddle.
Later on, Tuesday the 22nd morning brings glassy conditions again with 5ft from the south, 7-second period. The combined energy is moderate (264). Clean but not firing.
All in all, the standout window is Tuesday the 15th morning and Thursday the 17th. The Thursday afternoon has more size and grunt, but the morning glass-off on Thursday is the real gem. Crowds at Ferrugem can be a problem – it’s often busy – so getting out early on those days is key.
There are gaps here and there with no real recommendations, especially after the 22nd the quality drops off.
Stay stoked, 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.
