The Lowdown
G’day, this is Rusty. The forecast for the Aventureiro region is a bit of a mixed bag over the next 16 days, but there are a couple of windows that’ll get your heart pumping. The best of the bunch is way out early on, but there’s a few other moments worth paddling for.
The first proper action worth mentioning is Wednesday 10 September. That’s the standout. The morning session at Praia do Aventureiro is looking prime. We’re seeing a clean 6 ft south swell, period around 10 seconds, with glassy conditions and zero wind. The combined energy is pushing 995 – that’s moderate wave energy, but it’s got a bit of grunt behind it. The swell direction is from the south, which lines up nicely with the optimum east for this break. This is a point break, so expect some nice, longer lines off the points. The water temp is about average for this time of year.
Before that, the early part of the run is a bit of a struggle. You’ve got a big, solid swell from the 26th of August into the 27th, with some serious 15-second period groundswell pushing 7 ft and combined energy over 2000 – that’s strong. But the wind is a mess. Cross-on, onshore, and some rain showers make it a write-off. The size is also too big for beginners, and the conditions are poor. That’s a real shame, because the energy is there.
You’ll have a few days of dribble from the 28th through the 30th of August, with small, weak swells around 3 ft to 4 ft, and short periods. The energy drops to 2-digit numbers at times – weak stuff. The wind is mostly cross-on, so it’s not doing any favours.
A small glimmer shows up on Monday 31 August morning. The swell is only 3 ft from the east, period 9 seconds, but the wind is glassy. The combined energy is just 168 – weak. It’s surfable, but very ordinary.
Tuesday 1 September morning brings a bit more life. A 5 ft south-southwest swell, but the period is a short 7 seconds, so it’s a bit crumbly. The wind is cross-off and clean, and the energy is 345 – moderate. It’s a more promising session, but the short period means it won’t be holding as much shape.
Wednesday 2 September morning is another one to circle. A 6 ft south swell, 9-second period, and glassy conditions again. The energy is 558 – moderate. It’s a good, clean option, but it is a point break, and with a period under 11 seconds, it’s not a classic groundswell.
There’s a big gap of poor conditions from the 3rd to the 8th of September. The swells are small, the wind is either onshore or cross-on, and the energy is weak. A few sessions are glassy but the swell is tiny – 1 ft on the 6th afternoon, for example, with a very long 15-second period that’s going to be too straight and fat for this beachy setup. It’s more of a kite-surfing scene during those days than a paddle one.
Then we hit the jackpot on Wednesday 10 September morning. That’s the one. 6 ft south swell, 10-second period, glassy, calm air, and the energy is 995. It’s going to be clean and consistent. The break is a point, so it should handle the size well. This is your best bet in the whole 16-day window. Crowds are possible here, so get in early.
Honestly, the rest of the second week is a write-off. The 9th of September afternoon has a 6 ft south swell with a short 8-second period, but the wind is cross-shore, so it’s messy. The 10th is the only real standout. Keep an eye on the forecasts, but as it stands, mark your calendar for the 10th.
Rusty.

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 Praia do Aventureiro 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.
