The Lowdown
Alright, Rusty here again, switching to feet and Fahrenheit for you.
We’re looking at Praia do Aventureiro – a consistent point break that’s friendly for beginners. Water temp is about average for the season, nothing to write home about.
The highlight of the whole 16 days is Monday, September 7th. The morning has a clean 8ft S swell, period 11 seconds, with a light cross-off wind. The energy is pumping strong. But the afternoon is the real deal – glassy conditions, 6ft S swell, and the combined energy is still high. That’s the session you want.
Tuesday the 8th is smaller at 4ft, but the afternoon goes glassy again. Wednesday the 9th is tiny but clean with offshore wind. Thursday the 10th is clean in the morning with a 3ft S swell.
Friday, September 11th morning is clean with a 4ft S swell and light offshore wind. The period is a long 14 seconds, so this is proper groundswell, and at a point it’ll wrap in nicely. That’s your second-best call.
Saturday the 12th drops to 2ft and poor. Sunday the 13th, the wind howls and the 7ft S swell in the afternoon is messy – that’s a kite day, not a paddle day.
The second week starts with a messy 6-7ft on Monday the 14th, onshore wind. Tuesday, September 15th morning is clean with a 5ft SE swell and light cross-off – best of that week. It fades after that, with a few small clean days on the 17th and 18th. Then Saturday, September 19th brings a big 6ft S swell with a 14-second period and very strong energy – but the wind is onshore. It’s a long-range hope, not a guarantee.
The last few days are tiny, weak, and not worth paddling for.
So, the clear winner is Monday, September 7th afternoon – glassy and 6ft. Friday the 11th morning is the next best. Second week, aim for Tuesday the 15th morning, and keep an eye on Saturday the 19th if the wind cooperates.
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. 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.
