The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu.
First things first, the big picture. We’ve got a solid pulse of southerly swell hitting Praia do Aventureiro over the next couple of weeks, but the wind is going to be the main character in this story. The water is sitting at 73°, which is a touch warmer than average for this time of year – nice, a little bit of a bonus.
The standout session is hands down Wednesday morning, 26 August. It’s not a massive day for the experienced crew, but the conditions are pure magic. We’ve got a 6ft Southerly swell, dead calm wind, glassy as a mirror. The wave energy is strong at 1417, and the period is 12 seconds – that’s a proper groundswell with some decent shape. For a beginner-friendly point break that’s very consistent, this is as good as it gets. The swell direction is coming from the south, which matches the optimum swell direction for this spot. Crowds are possible here, so get in early.
The afternoon of the 26th sees the swell bump up to 7ft Southerly with a very long period of 15 seconds. That’s a lot of water moving – combined energy hits 2047 – but the wind shifts to a light cross-onshore, putting a bit of a wrinkle on the face. This is more of a look for the experts; 7ft with that long period will be bowling, and at a point, it could be a real treat, but the wind is a shame.
Thursday morning, 27 August, is still big with a 7ft Southerly swell and a 14-second period, but again, that cross-onshore wind keeps it from being perfect. The energy is still high at 1850. The rest of that week and into the next is a bit of a write-off. The wind is onshore or cross-onshore, the swell drops, and the scores reflect that. There’s a consistent run of poor to marginal conditions from Thursday afternoon right through to the end of August.
We hit a bit of a gap in quality. The first week of September looks a bit more promising wind-wise, but the swell is smaller. On Wednesday morning, 2 September, we get a 4ft Southerly swell with a light cross-offshore wind, and the energy is 294. Not a standout, but it’s clean. The afternoon of that same day is even better: 5ft Southerly, glassy wind, energy at 343. That’s a solid session for a fun, smaller wave.
The real potential for a late-period standout is Thursday, 10 September. The morning shows a 5ft Southerly swell with a 13-second period and a light cross-shore wind, energy at 819. The afternoon, however, is the big one: 7ft Southerly swell, period 12 seconds, and the combined energy is a massive 2722. The wind is a light cross-onshore, which is a bummer, but for an experienced surfer, that’s a lot of power on offer. This one is promising, but we’re a long way out, so keep an eye on it.
Overall, if you’re a beginner, Wednesday morning the 26th is your day. If you’ve got the skills, the afternoon of the 26th and the 10th of September are the ones to circle.
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.
