The Lowdown
Alright folks, Rusty here. Let’s take a look at what we’ve got coming up for Ferrugem. It’s a bit of a mixed bag, but there are some definite windows of opportunity if you’re patient.
The pattern starts off with a decent pulse of groundswell. Tuesday the 25th is looking like the first real go. Morning is the clear winner here. We’ve got a solid 6ft of SSE swell rolling in with a long 13-second period (979). That’s proper groundswell energy, and with the wind glassy from the NNW at 3 mph, the surface is going to be silky. The water temp is sitting around 66°, which is pretty average for this time of year, nothing weird going on. This is a standout session for the clean, lined-up waves.
That afternoon, the wind swings NE and picks up, putting a bit of a cross-chop on the face, so it’s not as good. Wednesday the 26th sees the swell bump up to 7ft from the SSE, but the period stretches out to a very long 15 seconds (1927). That’s a ton of energy, but at a beach break like Ferrugem, a swell that long can tend to jack up and close out. The morning is clean with a cross-offshore NNE breeze, making it look tempting, but it’s really one for experienced surfers only at that size. The afternoon gets messy with a strong NE crosswind.
Thursday the 27th is still fun, with 5ft of SSE swell (1040) and clean cross-off winds in the morning. It’s a step down in size, making it more manageable. Friday the 28th, the swell direction shifts to a short-period ENE windswell (8 seconds, 406). It’s clean but weak and won’t have much push.
We hit a bit of a lull from Saturday the 29th through to Monday the 1st of September. The swell is small and onshore winds make conditions poor to marginal. Not worth paddling out unless you’re desperate.
Then things get interesting again. Wednesday the 3rd of September brings a return of clean conditions. The morning is glassy with a 6ft SE swell (599) and a 9-second period. That’s a great combo for a playful, punchy wave with no wind to mess it up. Solid clean conditions.
The next standout is Sunday the 6th of September. This is the biggest swell of the forecast. We’re looking at 8ft of NE swell (1358) with a 9-second period. The morning shows clean, cross-off winds from the NNE at 9 mph. This is a beefy swell, definitely for the experienced crew. It’s going to be powerful and the long period could make it a bit tricky at the beach, but the conditions are right. This is a top-tier session for the confident surfer.
Tuesday the 8th of September is another good clean morning call with a 6ft NE swell (861) and light offshore winds. A very solid option for a broader range of surfers.
At Ferrugem, the crowds are often there, so don’t expect much solitude. For the standout sessions, especially the glassy Tuesday the 25th and the big Sunday the 6th, expect company.
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.
