The Lowdown
G'day, Rusty here, looking out for you at Praia do Aventureiro. The next couple of weeks are a bit of a mixed bag, with some real clean gems hidden in there, but you'll have to dodge some lumpy days to find 'em. The standouts are Monday the 7th and Tuesday the 10th of September – talk about glassy perfection.
Alright, let's kick things off. We've got a few small, pretty ordinary days to get through first. Saturday and Sunday the 5th and 6th are a write-off with tiny waves and messy cross-shore wind. Not worth paddling out. Sunday the 6th actually has 7ft swell, but it's got a short, weak period of only 8 seconds and is all cross-chop from a strong breeze. That's more of a windsurfing or kite day, to be honest.
Now, here's where it gets good. Monday the 7th September is the first real standout. The morning sees a clean 7ft southerly swell with a solid 10-second period and light offshore wind from the west. The wave energy is strong at 999. By the afternoon, it goes absolutely glassy with 6ft surf – that’s the session you want to be out for. The water's sitting at a touch warmer than usual for September, around 73°F.
Tuesday the 8th is a bit of a letdown after that, with smaller swell and onshore winds creeping back in. Then we get another little gem on Thursday the 10th of September. The morning is glassy again with 3ft of long-period (12 seconds) southerly swell, and the combined wave energy is a solid 356. The afternoon stays clean with a light offshore breeze. Same deal on Friday the 11th with glassy 3ft waves from the south, packing a very long 14-second period – real groundswell. That longer period means it'll wrap in nicely at this point break setup, with good shape and long lulls between sets.
The weekend of the 12th and 13th is a bit of a fizzer with tiny, weak swell, though Sunday afternoon blows up with a big 12ft swell from the SSW (1396 wave energy), but it's messy with strong cross-offshore wind. The following week gets interesting, but it's not perfect. The swell really jacks up from the 14th of September onwards, with the 14th Monday seeing 12ft of southerly groundswell (13 seconds) and massive wave energy at 3671, but it's coming with a light cross-onshore wind. That size is only for the experts; 12ft is well above what beginners can handle. Tuesday the 15th stays big at 8ft to 7ft from the SSE (12 seconds, 1782 energy), but still with a cross-onshore element.
Look, for the rest of that second week, we get some cleaner windows. Friday the 18th September morning is glassy with 5ft from the southeast, but it's a short period of 7 seconds, so it'll be a bit crumbly. Sunday the 20th September morning is another glassy session with 6ft from the east-southeast (8 seconds, 449 energy) – that's a decent option to end the outlook on. Crowds at this spot are listed as "sometimes," so you could have some company, but it's not a guarantee.
Overall, the best bet is hands down Monday the 7th, with Thursday the 10th as the top backup. The big stuff in the second week is powerful but needs cleaner wind.
Stay stoked,
Rusty

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.
