The Lowdown
Alright, grab your board, let's have a look at what's on the cards for Praia do Aventureiro over the next couple of weeks.
To be honest, it’s a bit of a slow-burner. We’ve got a fair few days of so-so conditions before a couple of proper windows open up. The water is sitting at a nice 73°F, which is about a touch warmer than normal for this time of year, so that's a bonus.
The first session worth paddling out for is Thursday afternoon, August 13th. That’s when things look clean. Swell is coming from the south at 6ft with a very long 15-second period – proper groundswell energy (combined energy of 1407). With glassy conditions and the wind swinging offshore from the south, this is the pick of the early run for experienced surfers. That long period might make it close out a bit on a beach break, but for this point, it could be pretty special.
Friday morning, August 14th, also looks good early. Similar south swell, 6ft at 13 seconds (combined energy 996), and it’s dead calm and glassy. A very good, clean surf option for the morning crowd, but don't expect it to last past lunch as the wind shifts onshore in the afternoon.
Then we hit a bit of a flat, ordinary patch for the weekend. There's a few smaller swells, but the wind and period aren’t lining up. Sunday the 16th is a write-off with a short period 5ft ESE windswell.
We get a little spike back on Monday morning, August 17th. The swell jumps back up to 8ft from the east, and it’s dead glassy again (combined energy of 1315). That’s a decent wave, but at that size it might be pushing into expert-only territory at this break. After lunch, it drops off and the wind swings onshore, so it’s a strict dawn patrol window.
After that, it’s mostly a week of small, poor quality waves and a lot of onshore wind. There are some glimmers – Tuesday afternoon August 18th is glassy but with a tiny 4ft swell, and the morning of August 25th has a moderate 5ft south swell with a nice 14-second period (combined energy 1026) but with a light cross-onshore breeze. Not really a standout.
The real highlights are Thursday afternoon the 13th and Friday morning the 14th. The best of the lot is that Thursday afternoon glassy session – the energy is solid, the wind is perfect, and you’ve got that long period swell wrapping into the point. Don’t miss it.

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. Our Praia do Aventureiro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Praia do Aventureiro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
