The Lowdown
Alright, this is Rusty. Let’s talk about what’s coming up for Ferrugem.
First up, we’ve got a bit of a slow start, but don’t be fooled – there are some real gems in the mix. The standout session is hands down Tuesday the 21st of July, first thing. We’re looking at 6ft of NE swell with a moderate 8-second period, and a light 6 mph N breeze giving us cross-off conditions. The water’s about average for this time of year, nothing wild. The combined energy is a solid 608, so there’s plenty of push. It’s going to be clean, punchy, and very consistent – this is the one to aim for.
The rest of the first week has some decent windows. Wednesday morning the 22nd is glassy with 4ft from the ENE and no wind at all. That’s a beautiful setup for a long session, but the energy is a bit lower at 215. Friday morning the 24th is another glassy morning, with 6ft from the SE, energy at 527 – that’s a bigger, cleaner wave, but it’ll be a bit more lined up. Saturday morning the 25th has 4ft SE swell with a light offshore from the NNW, making it clean and fun, but the period is short at 8 seconds.
After that, we hit a bit of a lull from Sunday afternoon through the middle of the following week. The swell drops off, and the wind picks up, making things messy or small. There’s a few small windows, like Wednesday morning the 29th with 3ft and glassy conditions, but it’s pretty ordinary.
Then, towards the end of the forecast, on Wednesday the 5th of August, we get a big spike. The morning shows 10ft of S swell with a 9-second period, and the combined energy is a massive 2194. That’s a lot of power. But the wind is a light cross-onshore, so it’ll have a bit of texture. That size is well into expert territory – not for the faint of heart. Still, a promising, if distant, standout.
Overall, if you can get out Tuesday morning, that’s your best bet. The long-range stuff on the 5th is worth watching, but it’s a ways off.
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.
