The Lowdown
Hey, Rusty here. Let’s talk about Ferrugem in feet and Fahrenheit for the next couple of weeks.
Right now it’s a bit of a slow start. Friday the 21st is messy – small, choppy, and not worth the paddle. Saturday the 22nd jumps up to around 8ft from the south, but the wind is cross or cross-on and the period is short. Combined energy is moderate (1826) but it’s still rough. Not a good call unless you like getting worked.
Sunday the 23rd drops to 5-6ft, with a little more period (11-12 seconds), but the wind is still not cooperating – cross and cross-on. Light breeze on the morning helps a bit, but it’s still a marginal day.
Monday the 24th is the standout. We get a long-period groundswell – 16 seconds – from the SSE, pumping at 8ft. Combined energy is a strong 4287. Wind is light and cross in the morning, so it’ll be glassy. This is over 8ft, so experts only. Best session of the run by far. Afternoon turns onshore and choppy, so you want the early slot.
Tuesday the 25th through Wednesday the 26th clean up with offshore to cross-off winds from the NNE, around 9 mph. Waves settle to 5-6ft with 12-14 second period. Combined energy is solid (954 to 1240). Clean, lined up, great for intermediate and above.
Thursday the 27th stays clean but drops to 4ft, still with long period from the SSE. Wind stays cross-off but picks up to 18 mph in the afternoon. Morning is your time.
From Friday the 28th through the end of the month, the swell mixes with short-period ENE waves, mostly under 5ft. Saturday the 29th morning is glassy, with 5ft from the ENE – “expect good surf conditions.” That glassy window is a nice little session.
The first week of September gets small. Swell stays under 5ft with short period. Friday the 4th and Saturday the 5th show a new SSE swell, 5ft to 6ft with 11-second period, and cross-off winds. Saturday the 5th morning is rated “very good” – clean, light winds, and 5ft from the SSE. That’s your best bet in the second week.
Water temp is 66°F, about average for late winter – nothing unusual.
Bottom line: Monday the 24th is the big one for pros. Tuesday the 25th and Wednesday the 26th are the clean, fun days for everyone else. And if you’re patient, Saturday the 5th looks solid.
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.
