The Lowdown

Hey folks, Rusty here. Let’s talk about what’s coming up for Ferrugem.

The next couple of days are a bit of a mixed bag, but there’s some real firepower on the horizon if you’re patient. The water temp is sitting about average for the time of year, nothing too wild.

Sunday the 30th morning is all about the glass. The wind is dead calm, and the swell is 3 ft from the east at 8 seconds. It’s surfable, but the energy is weak (155) – more of a longboard cruise than a proper session. By Sunday afternoon, the wind swings onshore and messes things up, so get it early.

Monday the 31st is where it starts to get interesting. Monday morning looks like a standout: glassy conditions, 7 ft of east swell, and the combined energy jumps to 501 (moderate). The waves should be clean and fun. Monday afternoon holds up with 7 ft east swell, light cross-off winds, and energy climbing to 705 – a solid afternoon session.

Tuesday September 1st morning is still clean with a glassy 6 ft from the ESE (energy 430), but the afternoon sees the wind turn cross-onshore and the quality drops off.

Wednesday and Thursday are a write-off for good surf. The swell is up but the wind is messy, with cross-shore and cross-onshore conditions making for chop. Not worth your time.

Friday September 4th morning offers a small, glassy 3 ft swell from the SE with a longer 10-second period, but the energy is weak (155). It’s a flat, clean morning for a quiet paddle.

The weekend into early next week is a bit of a gap. There’s nothing really recommendable until Sunday September 7th.

Now, here’s the big one. Sunday September 6th morning sees a massive 12 ft south swell (11 seconds) and energy readings of 4903 – that’s very strong. But the wind is a strong cross-shore, and the swell is too big for this break. It’s more of a spectacle than a session. Monday September 7th morning, however, is a true standout for experienced surfers only. You’ve got a 10 ft swell from the SSE, a very long 14-second period, and light cross-off winds. The energy is 3703 (very strong). The waves will be powerful and clean, but this is not for beginners – it’s solid, heavy groundswell. The long period means it’ll be better shaped but with long lulls between sets. Tuesday September 8th morning is also excellent for the same crew: 8 ft from the SSE, 14-second period, light cross-off winds, and energy at 2853. Still big, still clean.

After that, the swell drops gradually. Wednesday September 9th morning offers a much more manageable 5 ft SSE swell (12 seconds) with clean cross-off winds and energy of 547 – a good session for a wider range of surfers. The rest of the week into the second week is smaller, with mostly clean conditions but limited energy. Saturday September 13th brings a pulse of 8-10 ft east swell, but the wind is onshore and choppy, so it’s not the pick.

The absolute best windows are Monday and Tuesday mornings (September 7th and 8th) – big, clean, powerful, and for experts only. The Monday morning of September 14th has a 13 ft east swell with calm winds, but it’s too big for this break, so give it a miss.

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.
