The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for our stretch of coast. The only real player on the board for the next couple of weeks is Praia do Aventureiro. It’s a point break, consistent, and it’s going to be the main event. There’s a big gap of nothing after that, so let’s get into it.
The water is sitting at a warm 73°, which is over 4° above normal for this time of year, so you’ll be comfortable in a shorty or even just boardies if you’re tough enough.
We start off with some solid size. Monday the 10th through to Wednesday the 12th have some decent swell, but the wind is a bit of a mess – cross and onshore, with a combined energy in the strong range (1409 to 1887). The waves will be there, around 7 ft to 8 ft from the South, but the surface is going to be choppy. It’s surfable but not the cleanest.
The real standout window hits Thursday morning, the 13th of August. We’ve got a 6 ft S swell with a 12-second period, and the wind goes glassy – dead calm. The combined energy is still strong at 943, but with zero wind, this point break is going to be silky smooth. This is your best bet for the near-term. The morning session is the call.
Friday the 14th and Saturday the 15th are still holding at 5 ft to 6 ft from the South, but the wind is cross-on or light offshore. Not as perfect as Thursday, but still clean enough to have fun. Saturday morning has that light offshore wind from the West, which will clean up the faces nicely.
By Sunday the 16th and Monday the 17th, the swell is dropping and the wind turns onshore. The period drops to 8-11 seconds, and the energy falls off to moderate (275 to 537). It’s getting small and weak.
Then we hit a real dry spell. From Tuesday the 18th all the way through to Sunday the 23rd, the swell is tiny – mostly under 3 ft – and the energy is low (75 to 295). The wind is all over the place. There are a few clean moments, like Tuesday the 18th morning with a light cross-off, but the waves are just too small to get excited about. That’s a solid 6-day gap of poor surf.
We get a flicker of life on Monday the 24th of August. A 6 ft SW swell with a short 6-second period rolls in, but the wind is offshore from the SSW, keeping it clean. The energy is moderate at 349. It’s worth a look if you’re desperate.
The real standout in the second week is Tuesday the 25th of August. The morning session is glassy again with a 6 ft S swell (9-second period) and a combined energy of 604. That’s a solid, clean wave. The wind is dead calm, so it’ll be perfect. The afternoon picks up to 8 ft with a 13-second period, but the wind gets cross, so it’ll get a bit lumpy. If you want a good wave, get out early Tuesday morning.
Overall, it’s a patchy outlook. The first week has a few standout windows, especially Thursday the 13th morning, and then again late in the second week on Tuesday the 25th morning. The middle is a write-off. Don’t expect much consistency.
Rusty.

Information about the Praia do Aventureiro Surf forecast
The above surf forecast table for Praia do Aventureiro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Aventureiro can be found by selecting the local surf guide option on the grey menu.

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.
