The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Ferrugem over the next couple weeks.
Right off the bat, it’s a slow start. We’ve got cleanish little 4ft waves from the ESE on Tuesday morning, but the swell energy is weak at 277 and the wind is a bit of a cross-off, not glassy. Not worth paddlin’ out for.
The pattern through the rest of the week and into the weekend is mostly messy. Wednesday morning has 6ft from the SE with a bit more energy at 692 and a light cross breeze, but the quality is only marginal. The real issue is the afternoon clockwork of onshores, kicking up chop and killing the shape. This repeats day after day until we hit a dead zone Friday and Saturday with tiny, weak, and poorly winded waves.
Now, there is a true standout to get excited about. Tuesday the 8th of September – that morning and afternoon are absolute glass. The wind drops to nothing, glassy, and we’ve got 5ft to 5ft of SSE groundswell with a period of 11 seconds. The combined swell energy is 620 and 528, which is moderate but solid enough. That sort of long period groundswell will wrap into Ferrugem’s sandbar setup nicely, offering clean, lined-up walls. This is the best on offer by a mile. Crowds can be *often* here, so get there early for a piece of that.
Another moment to watch: Friday the 11th of September morning has 7ft of ENE swell with moderate energy at 824, but the cross-breeze spoils it. Not a goer.
Then we get another glassy gem on Saturday the 12th of September morning: 4ft from the SSE with a very long period of 12 seconds and glassy conditions. That’s a sneaky clean session if you like smaller, longer-period runners. Swell energy is high at 978.
Hold on for Sunday the 13th of September morning – that’s a big 10ft from the south with 13 seconds and a massive 5099 energy reading. That’s strong. But with onshore wind, it’s gonna be a messy, heaving mess. Only for the experts if anyone’s out, and even then, it’s not clean. The afternoon is worse.
Beyond that, the second week fades back into smaller, cross-breezy conditions with nothing to write home about.
So, for my money, Tuesday the 8th of September is the standout day – glassy, clean, waist to head high SSE groundswell. Saturday morning the 12th is the backup for a quieter, smaller glass session. The rest? Leave it.
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.
