The Lowdown
Alright, let’s break it down. The next few days are a bust – small, weak, short-period junk and bad wind. You’re looking at a three-day gap before anything worth paddling out for shows up.
Monday the 3rd of August morning sees a tiny 0.9m swell from the ENE, period a weak 8 seconds. Combined energy is only 122 (moderate). Wind is a light cross-offshore from the NNE, so it’s clean, but the waves are gutless and ordinary. Barely a session.
Tuesday the 4th of August morning is where it gets interesting. Swell drops to 0.8m but switches to the SSE with a 12-second period – proper groundswell. Combined energy jumps to 290 (moderate). And the wind? Dead calm, glassy. That’s the good stuff. The waves will be small but beautifully shaped, with clean, long lines. Perfect for a longboard or a funboard.
Wednesday the 5th of August morning is similar – glassy conditions again, with a light breeze. Swell holds at 0.8m and 10 seconds from the SSE, combined energy at 180 (moderate). Clean and fun, but still on the small side.
Then things get messy with onshore wind Thursday and Friday. Not worth it.
Monday the 10th of August morning is your first real standout. Swell pumps up to 1.8m from the south, period only 6 seconds (windswell), but combined energy is a solid 330 (strong). The wind is a clean cross-offshore from the NNE, so the surface is good. That’s a fun, punchy session for intermediate surfers.
Tuesday the 11th of August morning is another good one. 1.7m from the south, period now 10 seconds – better quality. Combined energy is 622 (strong). The wind is light cross-shore from the SSW, so the waves will have more shape and power, but the surface won’t be perfect.
After that, the swell keeps building. Wednesday the 12th of August morning sees 2.0m, and by Thursday the 13th of August morning it’s a massive 3.0m from the south with a 13-second period. Combined energy is enormous at 4690 (very strong). That’s big, powerful groundswell. The wind is a light cross-onshore from the ESE, so it’s doable for experts, but at that size and period on a sandbar, it’s going to be heavy and closing out. Stay away if you’re not solid.
Saturday the 15th of August morning is the last real highlight. Swell drops to 1.8m from the SSE, still a nice 12-second period, combined energy of 907 (strong). The wind goes light offshore from the north – clean, lined-up, and powerful. That’s a proper session.
Best bets: Tuesday the 4th of August morning for the glassy, quality groundswell, and Monday the 10th of August morning for the first bit of real size with clean wind.

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.
