The Lowdown
Alright, fellow surfers, it’s Rusty here, and I’ve been staring at the charts for our stretch of coast. Let’s get into it.
We’re looking at a real mixed bag over the next 16 days. There’s a bit of a wait for the first real surf, and then we’ve got a few windows where it could get good, but you’ve got to be patient. The early part of the run is a total write-off, so don’t bother paddling out until we get past the first week of August.
The first real chance to get wet comes on Monday morning, the 3rd of August. Ferrugem is the only option, and it’s a sandbar break. The water is sitting at 66°F, which is pretty average for this time of year. We’ve got a clean 4ft swell from the NE with a short period of 8 seconds, and the wind is a light offshore from the NNE. The combined energy is moderate (280). It’s not huge, but it’s clean and rideable. This is a decent warm-up. The afternoon turns a bit messy, so hit the morning session.
The next standout is a cracker. On Tuesday morning, the 4th of August, the wind goes glassy, dead calm from the south. The swell is a clean 3ft from the SSE with a long period of 12 seconds, giving it some real grunt and shape. The energy is moderate (338). This is the kind of morning that makes you forget about the flat spell. Ferrugem will be a bit of a gem, but given it’s “often” crowded, expect some company for those clean lines.
The surf stays small and marginal for a few days after that, with a mix of light winds and cross-shore chop. Keep your eyes on Friday morning, the 7th of August. We’ve got glassy conditions again with a 5ft swell from the S, but it’s a short 7-second period. The energy is getting stronger (415). It’s a bit of a lumpy, powerful close-out for a beach break, but if you’re an experienced surfer, the raw power might be fun.
Now, the real heavyweight of the whole forecast lands on Monday morning, the 10th of August. This is the one. Ferrugem gets a solid 7ft groundswell from the SSE with a very long 13-second period. The combined energy is massive (1268). The wind is a light offshore from the SW, keeping it clean. This is expert territory for sure, over 8ft, and for a sandbar, that long period means it’s going to be powerful and possibly a bit straight. But for the charger, this is the best session on offer. Seek it out if you’ve got the skills.
The following week sees a few more clean windows. Wednesday morning, the 12th of August, has a nice 6ft NE swell with a clean offshore wind. The period is short (7 seconds), but the energy is strong (550). It’s a solid, fun size for intermediates. And on Thursday morning, the 13th of August, there’s a clean 4ft ENE swell with light offshore winds.
Overall, the clear winner is Monday the 10th of August for the big, clean, powerful groundswell. The Tuesday the 4th and Wednesday the 12th are your best bets for a more user-friendly, clean session.
Rusty, out.

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.
