The Lowdown
Alright, Rusty here, let's break down what we’ve got.
Starting off, it’s a bit quiet. Monday is a total loss with the wind blowing straight onshore and the swell all messed up. We’re in a waiting game for a couple of days.
The first real chance to get out comes Tuesday morning, September 15th. The swell is only about 3ft from the S, but it’s got a little bit of period at 11 seconds. The wind is a clean offshore, so Praia do Aventureiro could be pretty fun for the beginners, even if it’s a touch inconsistent. The water’s sitting at 73°, which is a touch warmer than you’d expect for this time of year, so that’s a nice bonus.
Wednesday the 16th stays small but clean. The afternoon session on Wednesday is the pick of the week for the pure beginner. That 2ft S swell has a long 12-second period, and with glassy conditions it’ll be as easy as it gets. Wave energy is moderate (318), so don't expect any power.
Thursday the 17th is a complete mess. The wind swings onshore and howls up to 16 mph, and the swell jumps up to 5ft. The combined energy is strong (795), but the conditions are poor. This is more of a kite-surfing day than a paddle day.
The following week gets a bit more interesting but comes with a big caveat. By Sunday, September 20th, we’ve got a solid 7ft E swell rolling in with moderate energy (964). The morning looks promising with light cross-shore wind. This is the biggest swell of the period, and it’s heading into the 6ft+ range, so it’s not for the faint of heart – definitely for the experienced crew.
Then, a real standout appears. Monday, September 21st, brings a beautiful little window. The swell drops back to a manageable 4ft from the ESE, but the real story is the wind: glassy, dead calm conditions all day. The water will be smooth as a lake. It’s not the biggest, but for clean, fun waves with no crowd pressure, this is the one to circle.
After that, we drop right off again. From Tuesday the 22nd through Saturday the 27th, it’s tiny. The energy is weak, often below 100. A few clean moments but nothing worth getting excited about.
Look ahead to Monday, September 28th. The afternoon brings a promising S swell, 5ft with 11 seconds and a clean offshore wind. The energy is strong (661). This is another good option for the more experienced surfer, but it’s two weeks out, so keep an eye on the forecasts.
So, the bottom line: The absolute best bet for a clean, fun, stress-free session is Monday, September 21st, with glassy conditions and waist-high waves. For the bigger wave crew, Sunday, September 20th offers the most size, but it’s for experts only. The week of the 28th has potential, but it’s a long way off.

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.
