The Lowdown
Alright, let me break it down for you. The next few days at Ferrugem are a mixed bag, but there's some real potential hiding in the second week. The water's sitting at 66°F with a tiny anomaly of 0.5°F, so it's pretty much what you'd expect for this time of year—nothing to write home about, but not a shock to the system either.
The week starts slow. Wednesday the 19th is a write-off with poor surf conditions and a weak 4ft ENE swell at 8 seconds, coupled with a cross-shore wind. Thursday morning the 20th cleans up a bit with a cross-offshore breeze and a 3ft ENE swell, but the energy is still low. Friday morning the 21st is the first real glimmer: a clean 5ft SSW swell, period 7 seconds, and light cross-off winds. It's not huge, but it's rideable and the conditions are tidy. The afternoon gets chopped out, though.
Saturday the 22nd brings a bigger pulse—7ft S swell Saturday morning, but it's lumpy with a cross-shore wind and a marginal forecast. The energy jumps, so there's some push, but the quality is questionable. Sunday the 23rd is a bit of a letdown with onshore winds and a messy 5ft S swell in the afternoon. There's a gap in quality here until Monday.
Now, Monday the 24th is the standout. Monday morning is glassy, with a solid 8ft SSE groundswell at 13 seconds and massive energy. That's serious power. With the period that long, it'll be a proper groundswell, best suited for experienced surfers—too big for beginners. The wind is glassy, so it'll be clean, but watch out for those long-period lines at a sandbar; they can be a bit wonky. The afternoon goes cross-on, so hit the morning.
Tuesday the 25th holds fun 5ft SSE swell with cross-off winds and clean conditions, especially in the afternoon. Wednesday the 26th stays clean with a 5ft NE swell in the morning, but the period drops to 7 seconds, so it'll be a bit weaker. The rest of the week into early September is a mix of small pulses and messy winds, with a few clean sessions on the 30th and 31st.
Looking ahead, Thursday the 3rd of September is another gem. Both morning and afternoon are glassy with 6ft and 5ft SSE swell, period around 12 seconds, with solid energy. That's a classic setup—clean, decent size, and offshore vibes. It's a long way out, but it's promising.
Overall, the best bet is Monday the 24th for the biggest and most powerful swell, with Thursday the 3rd as a backup glassy session. Crowds are often a thing at Ferrugem, so expect company on the good days.

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.
