The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Ferrugem.
Right off the bat, it’s a bit of a mixed bag. The first few days are pretty ordinary with a lot of marginal and poor conditions, but there’s a real standout window brewing for the start of September. The water temperature is sitting at 64°F which is about average for this time of year, so no surprises there.
The first real glimmer of hope comes on Saturday the 29th of August, afternoon. The breeze goes glassy, and while the swell is only 5ft from the east-northeast with a short 8-second period, it’s clean and the energy is moderate (311). Not a world-beater, but it’s surfable.
Sunday the 30th has a similar story, but with light rain and light winds. The morning sees 4ft east-northeast swell, period still short at 8 seconds, and moderate energy (225). It’s clean, but nothing to write home about.
Monday the 31st stays consistent with 4ft east-northeast swell, period creeping up to 9 seconds, and moderate energy (341). Light winds in the morning keep it clean.
Now, the real standout. Wednesday the 2nd of September, morning. This is the one. The swell jumps to 8ft from the south-southeast with a period of 11 seconds, and the energy is strong (1346). The wind is glassy, making for excellent conditions. This is a proper groundswell, and it’s going to be clean and powerful. This is only for experienced surfers, though – 8ft is solid and the long period means it’ll have some punch. Keep an eye on it.
The rest of the second week is a bit all over the shop. Thursday the 10th of September, afternoon, looks promising with 5ft SSE swell, 9-second period, moderate energy (666), and clean conditions. It’s a solid option.
Friday the 11th of September morning brings a bigger swell – 7ft from the east, 8-second period, strong energy (790) – but the wind is onshore and choppy, so it’s not the best call.
Overall, there’s a lot of average days, but the Wednesday the 2nd morning window is the one to circle. The rest of the second week has some decent pulses but the wind is often against you. Keep your hopes up, though – it’s not all bad.
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.
