The Lowdown
Alright, crew, Rusty here layin’ it out for Ferrugem for the next couple weeks. We got a slow start, but there’s some juice if you’re willin’ to wait.
This spot is a sandbar, breaks real consistent, faces the swell and wants it from the southeast. Water temp is 62° right now, which is 4° colder than normal – that’s a big chill, so bundle up when you finally get wet. Tuesday the 15th is a total dud: weak, short-period swell of 3 to 3ft from the SSE, light cross-shore breeze, and just weak wave energy. Not worth your time.
Wednesday the 16th morning is your first chance – 5ft of SSE swell with glassy conditions. Wave energy is moderate (298). Afternoon you get a choppy onshore mess. Thursday and Friday stay small, knee-high surf with average conditions.
Sunday the 20th is where we go. Morning is meh, but Sunday afternoon is a real standout. Swell jumps to 6ft from the ENE, wave energy hits 750 (strong), and the wind is cross-offshore – clean. Best session of the first week. It’s a little heavy for beginners, and crowds are possible. Monday the 21st morning is also choice – 5ft ENE, glassy, moderate energy. That’s two back-to-back clean windows.
The middle of the week gets smaller and choppier, but Wednesday the 23rd morning is clean with 4ft ENE swell. Towards the end of the forecast, from Monday the 28th through Wednesday the 30th, we get a long-period groundswell. On the 28th afternoon, wave energy is massive at 1331 with a 16-second period from the SSE, but it’s onshore and messy. Tuesday the 29th has 5ft SSE swell at 13 seconds (energy 1001) and the wind goes cross-offshore by afternoon – clean. That’s a promising long-range call, but beware – those super long period swells can close out on a beach break. Wednesday the 30th afternoon has offshore wind and clean 4ft ENE swell.
Bottom line: skip the first four days. Sunday the 20th afternoon is your best bet early. The final days of September throw some serious power, but it’s only for the experienced set when it’s over 5ft.
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.
