The Lowdown
Alright, Rusty here, let’s break it down for the imperial crew.
We kick off on Tuesday, August 11th, with a solid SSE swell running about 7 ft, 12-second period. That’s got some nice energy pushing in at 1140. The water’s sitting at 66°, right around normal for this date. Tuesday morning has a light cross-shore from the SSW, but the afternoon glass-off from the ENE is the real gem – clean, chest-to-head-high waves at 6 ft. That’s the first standout: glassy, lined up, and ready to go.
Wednesday and Thursday see the swell holding around 6 to 6 ft, but the wind stays up from the NNE, making it a little bumpy. Still surfable, but not the cream of the crop.
Friday the 14th morning gives us another glassy window. Offshore wind from the NW, swell at 5 ft from the SSE, 13-second period. Clean and tidy. That’s your second nice session, though the swell is smaller.
Saturday the 15th drops to 4 ft, and by Sunday the 16th, the swell goes short and weak. Energy drops into the 300s. From Tuesday the 18th through Saturday the 22nd, we hit a flat spell. Waves are under 3 ft most days, weak period, onshore wind. Not worth the drive.
Sunday the 23rd sees a little bump from the south, 4 ft at 8 seconds, with glassy morning conditions. Soft but possible.
Then comes the big one. Tuesday, August 25th. Swell hits 8 ft from the SSE with a 16-second period. The combined energy jumps to 3151 – that’s serious power. The wind is cross-off from the north, light, keeping the faces clean. This is a groundswell for experienced surfers only. Long waits between sets, but when they come, they’re bombs. It holds into Wednesday the 26th at 7 ft with a 14-second period and light offshore wind.
Don’t waste your energy on the flat middle part. Aim for the 25th and 26th. That’s the real deal.
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.
