The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
We’ve got a slow start, but things really kick off this Sunday morning, August 23rd, at Praia do Aventureiro. The water is sitting at 74°, which is a solid 4° warmer than usual for this time of year – that’s a real treat, feels like a late summer gift. Sunday morning is the standout early call. We’re looking at a 5ft south swell, with a nice 10-second period, and the wind is glassy from the ENE. That’s clean, beginner-friendly, and the combined energy is moderate at 444. It’s a point break that’s very consistent and fairly exposed to the south swell, which is exactly what we want. It’s best for the beginner crew, but the conditions are so clean everyone will be having fun. Just a heads up, it can get crowded sometimes.
The surf builds through Monday and Tuesday, but the wind and rain mess things up. The swell gets bigger – up to 7ft to 8ft with a very long period of 13 to 14 seconds from the south, and the energy goes through the roof (over 1600 and 2000). But the wind is onshore or cross-onshore, and there’s light rain, so the quality drops. The larger sizes (over 5ft) are getting a bit much for beginners, and the conditions are marginal.
The next real bright spot is Thursday morning, August 27th. The swell drops back to a clean 6ft from the south, with a long 14-second period and glassy conditions from the SE. The energy is still strong at 1401. This is excellent for experienced surfers – the point break will handle that long-period groundswell beautifully. This is likely the best session of the whole run, with clean waves and light winds.
After that, the swell fades away. Friday the 28th drops to 4ft, and by Saturday the 29th it’s all small, crummy windswell from the east around 3ft with a short 8-second period. The energy is weak (under 200). We’re looking at a big gap of poor to flat conditions. From the 29th of August all the way through to the morning of the 3rd of September, there’s really nothing worth paddling out for. It’s all small, weak, and blown out.
Then, on the 3rd of September, we see a pulse of 7ft south swell with a 12-second period, but the wind is onshore, and the quality is poor. The energy is strong at 1169, but it’s not going to be clean.
The final hope comes on Friday, September 4th. The morning and afternoon both look promising. We’re back to a 5ft to 5ft swell from the SSE, with a 10-second period and glassy conditions. The energy is moderate (487 and 434). This is a solid, clean end to the window. The water temperature won’t be as warm as the start, but it’s a good option for a surf.
So, to wrap it up: the best on offer is hands-down Sunday morning, August 23rd, for the clean, warm beginners’ waves. The absolute standout for technique and quality is Thursday morning, August 27th, for the experienced crew. The second week looks very quiet, but the 4th of September offers a final glassy chance. It’s a run of two halves – a strong start, a long lull, and a quiet finish.
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.
