The Lowdown
G’day, Rusty here. Looking at the 16-day stretch ahead for Ferrugem, and I’ve got to be straight with you—there’s a bit of a slow start, then a few moments that’ll get the heart pumping, but nothing that screams “drop everything and go.” The first proper recommendation doesn’t kick off until Monday morning, July 20th, so don’t bother checking before that.
We start Monday morning, July 20th, with a clean 5 ft swell out of the ENE, period a short 8 seconds, and glassy conditions—wind’s barely a whisper from the NNW at 3 mph. It’s surfable, but the energy’s moderate (274) and that short period means mushy, weak waves. Not a standout, but a decent warm-up if you’re keen. The afternoon turns into a bit of a mess with rain and onshore wind from the SE, so skip it.
Tuesday, July 21st, looks tidy. Both morning and afternoon offer clean surf around 4 ft to 4 ft from the ENE, still short period, but cross-off winds from the N and NNE at 6 mph keep things workable. The energy’s around 210–262, nothing special, but it’s a quiet, consistent day—good for a long session.
Then Wednesday, July 22nd—pay attention. The afternoon brings offshore wind from the NNW at 9 mph, clean and glassy, with a 4 ft ENE swell. The energy’s still moderate (214), but that offshore breeze makes it feel like more. This is one of the better windows for a relaxed, clean surf before things get weird.
Thursday, July 23rd, the swell jumps up. Morning has 7 ft from the S with a 9-second period, but the wind is cross-shore from the SW at 12 mph, creating a chop. Energy is up to 1209—strong—but the conditions are marginal. The afternoon’s similar at 7 ft with cross-onshore wind. This is more for the experienced crew; beginners will struggle with the size and bump.
Friday, July 24th, drops back a bit to 5 ft in the morning from the SE, but onshore wind from the ESE ruins it. Afternoon’s 5 ft with cross-shore wind and a light chop. Not recommended.
Saturday, July 25th, is a write-off—heavy rain, cross-onshore winds, poor surf. Sunday, July 26th, brings a decent 7 ft swell from the ESE but cross-shore wind at 12 mph creates a rough sea.
Now, hold onto your leash—Monday, July 27th, is the real standout. Morning has 6 ft from the ESE, period stretching to 10 seconds, and glassy conditions with NW wind at 3 mph. The energy’s 599—moderate but building. The water temperature is about average for this time of year, nothing unusual. This is the cleanest, most promising session of the whole run. Afternoon turns cross-shore and choppier, but that morning will be magic.
Tuesday, July 28th, the wind picks up hard—NNE at 16–19 mph, cross-off but blowing strong, making the 5 ft to 4 ft swell messy and unappealing. Wednesday, July 29th, lightens up to 3 ft with clean cross-off wind from the N at 6 mph—small but fun.
From July 30th, things fade. Thursday morning offers a short-period 5 ft from the NE, clean, but the energy’s low (329). Then we hit a long gap: from Thursday afternoon through to Saturday, August 1st, it’s all poor conditions or very small surf—2 ft to 4 ft—with messy winds. Sunday morning, August 2nd, pops up with a clean 2 ft from the S, period 11 seconds, energy 225—tiny but glassy, maybe worth a paddle if you’re desperate.
The last blip is Monday, August 3rd, with 4 ft from the SSE, clean but cross-off wind at 12 mph, energy moderate at 349. Not a standout.
Overall, the best bet is Monday morning, July 27th—clean, glassy, consistent, with a solid ESE swell. Wednesday afternoon, July 22nd, is a close second for that offshore glass. The rest is small or choppy. Keep an eye on the forecast—these things can change.
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.
