The Lowdown
Alright, grab your wettie, let's have a look at what’s coming our way for the next couple of weeks.
Right off the bat, Thursday and Friday this week are looking a bit average. The water’s sitting at a balmy 74° – that's much warmer than normal for this time of year, so you can leave the booties at home. Thursday morning has a 6ft south swell running, but the wind is cross-on from the NE at 6 mph, making it messy. That cross-on breeze is not doing us any favours, and the energy feels moderate at 801. Not great. Thursday arvo gets worse with onshore easterly wind – a write-off. Friday morning, however, is a nice little window. The wind goes glassy, flat calm, with a clean 3ft south-southeast swell. It’s small, but it’ll be clean as a whistle, perfect for the beginners. The energy is moderate (381). That’s the pick of the early days, but only for those on a longboard or a foamie.
The weekend is a write-off. Saturday has a tiny 2ft bump with onshore winds, and Sunday gets a bit of size back to 4ft with offshore wind, but the score is low and conditions are ordinary. Not worth paddling out for.
Next week starts slow. Monday and Tuesday look poor – messy cross-onshore wind and wind ripples, with the swell sitting around 5-6ft but just ugly. The combined energy is moderate to high (554-631), but the wind is killing it.
Now, look ahead – Tuesday the 15th of September is where it gets interesting. We’ve got a solid 8ft south swell rolling in with glassy conditions on the morning. The wind is a whisper, and the wave energy is strong (1060). That is the standout of the entire outlook. The water should still be warm, and the point break at Praia do Aventureiro will handle that size well. It’s a consistent spot, and with the offshore direction being west and the swell coming from the south, it’s going to be firing. Expect clean, powerful lines. That’s the day to call in sick.
Thursday the 17th of September also has a little gem in the afternoon. The wind goes completely glassy, flat calm, and there’s a nice 4ft south swell, but the period is a very long 13 seconds. That means it’ll be a proper groundswell, with energy (968) and nice shape on the point. Sets will be spaced out, making paddling easy, and the waves will reel down the point. Very clean.
Then on Friday the 18th, we get a proper pulse. A 7ft south swell with a very long 16-second period. The combined energy is very strong at 2874. But the morning wind is a cross-off 12 mph, so it will be clean but a bit onshore on the face. By the afternoon, the wind swings cross-shore and gets choppy. This size (7ft) is pushing expert territory, and the period is so long that it might stand up a bit too straight for the beach, but the point at Praia do Aventureiro should handle it beautifully. If you’re an experienced surfer, Friday morning is a solid option, but Tuesday the 15th is still the king.
So overall, the pick is Tuesday the 15th of September, followed by Thursday the 17th afternoon. The rest is pretty average. Stay patient, and you’ll get some gems.

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.
