The Lowdown
Alright folks, Rusty here. Let’s get into this one. We’ve got Ferrugem to look at, and for the first few days it’s a bit of a mixed bag, but there are some real gems hiding in the forecast if you pick your moments.
The pattern starts off Monday the 7th with a bit of a sad note. The swell is there at 5ft from the south, period hitting 10 seconds, but the wind is a mess – cross and cross-on with ripples. The wave energy is moderate at 504, but it’s just not clean. You’d be fighting chop. Don’t bother.
Tuesday morning the 8th is where it starts to get interesting. The swell drops a touch to 4ft, still from the SSE, but the wind goes cross-offshore from the NNE. That’s a light breeze, and the forecast says clean. The energy is still moderate (388). This is a solid option for a smooth, intermediate session. The afternoon goes downhill with strong cross-shore wind, so go early if you want in.
Now, Wednesday the 9th morning is a real standout. The swell is 3ft from the SSE, nothing huge, but the wind is glass – absolutely zero. The ocean is calm, and the energy is back up to 502. This is about as good as it gets for a clean, fun wave on a longboard or a mid-length. The water temp is about average for the time of year, so no surprises there.
Thursday the 10th is another beauty. Morning brings 3ft SSE swell, cross-offshore wind, and clean conditions. The energy is 504 – solid for the size. But the afternoon is the real winner. The swell picks up to 3ft, the period stretches to 15 seconds, and the wind goes light offshore from the NW. That’s a long period groundswell, and it’s going to reel down the sandbar with some real push. Clean, glassy, and the energy is 593. This is your best bet for the first week.
The next few days are a bit of a letdown. Friday the 11th still has clean waves in the morning – 2ft, cross-offshore – but it’s small. By Saturday the 12th, the wind swings onshore and the swell gets short and weak. We’re in a lull.
Then we get a big pulse. Sunday the 13th brings a 8ft swell from the SSE, with a period of 11 seconds and a massive energy of 1434. But the wind is a howling cross-onshore, and it’s choppy. That’s a lot of power, but it’s messy. Only for the hardcore.
Monday the 14th is the big one. The swell is still 7ft from the SE, period 10 seconds, and the wind is glass. The energy is 942. This is a powerful, clean swell. The wind is calm, so it’ll be glassy. This is a standout for experts – that size is too much for beginners. The water temp is still about average.
The run continues through the week with solid, clean swells in the 5ft to 7ft range, but the wind is a bit more mixed. The periods drop to 8-9 seconds on some days, which is shorter. Thursday the 17th has a 6ft swell from the south with a cross-shore wind, so it’s not perfect.
The second week gets a bit iffy. Friday the 18th has a 7ft SSE swell, period 14 seconds, and energy of 1661. That’s a lot of energy, but the wind is cross-onshore. It’s promising but not a lock. Saturday the 19th is cleaner with cross-offshore wind, but the swell drops to 5ft.
Sunday the 20th is another big pulse – 8ft from the NE, but the period is short at 8 seconds and the wind is a strong cross-shore. That’s more of a wind swell, and it’s going to be choppy.
The last real highlight is Monday the 21st. The swell is 5ft from the ENE, period 8 seconds, but the wind is glass. Calm conditions. The energy is 342. It’s not the biggest, but it’ll be clean. Then Tuesday the 22nd morning brings a 5ft ENE swell again, cross-offshore wind, and clean conditions. A good way to finish the run.
So, the standout here is Thursday the 10th afternoon for the clean, long period groundswell with offshore wind. The second best is Monday the 14th morning for the glassy, powerful swell. After that, pick your clean windows.
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.
