The Lowdown
Alright folks, Rusty here. Let's have a look at what Praia do Aventureiro has in store for us over the next couple of weeks.
First off, the water temp is sitting at 72°, which feels a touch warmer than normal for this time of year. That's a nice little bonus if you're paddling out in just a shorty.
Right now, there’s nothing to get excited about. We're looking at a long, flat gap. The first decent window doesn't open up until Wednesday the 26th of August. Until then, it's mostly small, weak, and messy, with swell energy barely registering. There's a brief spike of moderate energy on the 22nd, but it's crossed up and lumpy.
Let's talk about the standout, and it's a good one. Wednesday the 26th into Thursday the 27th. That's the real deal. We've got a solid S swell pushing through, about waist to chest high. What makes it special is the wind. You're looking at glassy conditions Wednesday afternoon and again Thursday morning. Absolutely clean. The swell period is a long 13 to 14 seconds, which brings in proper groundswell energy. The combined energy readings are solid, not overwhelming, but enough to give you a good push. For a point break like this, that long period is perfect. It'll wrap in nicely and offer some quality lines. Aventureiro is a beginner-friendly wave, and this swell is right in that sweet spot, not too big, just fun.
Thursday afternoon the wind shifts a little onshore, but it’s still light. The waves hold through the morning of the 28th, though the size starts to drop and the wind goes cross, turning things a bit scratchy.
After that, the energy fades away quickly, and we’re back to small, weak dribble right through the end of the month. The second week looks pretty ordinary, with nothing worth planning a session around from that point. A couple of glassy mornings with tiny waves, but nothing with any weight.
So, mark your calendar for Wednesday the 26th and Thursday the 27th. That’s your window. The rest of the run is mostly a write-off, but when it's clean and lined up at a consistent point like this, it makes the wait worthwhile.
Rusty.

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.
