The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks at Praia do Aventureiro.
First thing you’ll notice is the water is sitting at 73°F, which is a touch warmer than normal for this time of year – a nice little bonus for the session.
The overall pattern is slow to start. There’s really nothing worth getting excited about until we hit the weekend of the 9th. The first few days are a bit of a write-off, with small, weak swell and poor winds. We’ve got a bit of a gap in solid surf here.
Tuesday 4th August is a no-go. The morning is glassy with tiny 3ft swell from the ESE, but the combined energy is weak (133) and the period is a short 7 seconds. Not worth the paddle.
Wednesday 5th and Thursday 6th are similar – small, messy, and uninspiring. The wind is all over the place, and the swell is just too small and weak to do anything with.
Friday 7th afternoon finally shows a little life. The wind goes offshore from the W at 15 km/h, cleaning things up, but the swell is only 2ft. It’s ridable, but barely.
Saturday 8th morning is clean with a light offshore, but again, only 2ft on offer. The afternoon sees a pulse of 4ft from the S, but it’s onshore and messy.
Now, Sunday 9th August is where we start talking. The morning is the standout of the weekend. We’ve got a clean 5ft swell from the S, with a solid 13-second period – that’s real groundswell energy (719). The wind is offshore from the W at 15 km/h, keeping it glassy. This is a proper point break session, and with that long period, it’s going to hold up well here. The afternoon gets a bit windier and bigger at 5ft, but the morning is the pick.
Monday 10th August – absolute glass! The morning is dead calm, wind from the W at only 5 km/h, with a 6ft S swell. The combined energy is strong (734), and the period drops to 11 seconds, which is still very solid. This is a top tier morning for a point break, super clean. The afternoon drops off a bit in quality.
Tuesday 11th August – another glassy morning, wind is calm, and the swell is 5ft from the S with a 12-second period (644 energy). This is consistent, clean, and powerful. A real treat.
Wednesday 12th gets messy. The swell jumps to 6ft, but the onshore ESE wind at 15 km/h is going to chop it up. The energy is very high (1051), but it’s not going to be pretty for paddle surfing. The afternoon is even worse with 20 km/h onshore. This one might be more interesting for the kite crew.
Thursday 13th is a step down in size and quality. Not worth a special trip.
Friday 14th August – look out. The morning is glassy again, with a 4ft S swell and a long 13-second period. The energy is pumping (864). This is going to be another clean, long-running groundswell session at the point. The afternoon gets a bit cross-shore, but the morning is gold.
Saturday 15th is clean in the morning and afternoon, but the swell drops a little. Still a solid 4ft to 5ft with good period. A good day, but not the highlight.
Sunday 16th is marginal, with onshore winds messing up a decent 4ft swell.
Monday 17th – glassy morning again! 3ft from the S with an 11-second period. Clean, but small. A fun little session if you’re out there.
Tuesday 18th is a drop-off, with tiny 2ft swell.
And then Wednesday 19th August – this is the real standout for the whole forecast. The morning is dead calm, glassy, and the swell is 7ft from the SSW with a 10-second period. The combined energy is very strong (823). That’s a big, powerful, clean swell. It’s going to be a heavy day at the point. This one is for the experienced crew only – 7ft is pushing it for beginners. The afternoon gets bigger at 8ft, but the onshore wind spoils it. The morning is the one to circle on your calendar.
So, to sum it up: the best windows are Sunday 9th morning, Monday 10th morning, Tuesday 11th morning, Friday 14th morning, and the absolute standout is Wednesday 19th morning. The rest is a mix of small, onshore, or just average. Get in the water while it’s glassy.
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.
