The Lowdown
G’day, Rusty here. Let me level with you—this coast is going to keep you honest for the next couple of weeks. Praia do Aventureiro is a point break that likes clean lines, but the ocean’s going to throw a lot of junk at it. There’s some fun to be had, but you’ll need to dodge a heap of poor days to get it.
Right off the bat, Tuesday afternoon is nothing flash. A little south swell at about 3ft, 10-second period, with a cross-off breeze and light rain—moderate energy at 233, so it’s just average. Wednesday morning is a bit cleaner with a light offshore, but still small. Later on Wednesday, it gets interesting: the breeze goes light, the period stretches to 12 seconds, and the energy bumps to 300. That’s the first clean, well-shaped window, and it’s coming from the south, which is right for the point.
Then things turn ugly. Thursday through Friday, the wind swings onshore out of the east, blowing 15–25 km/h. The swell builds a bit—up to 5ft on Thursday—but with that wind and shorter period, it’s messy. Energy jumps to 399 and 578, but it’s not doing anyone favors. Saturday stays poor, with cross-onshore winds and a swell that builds to 5–6ft, but the period drops to a weak 7 seconds. That’s just wind-slop. Sunday morning brings the biggest swell of the run at 6ft from the east, but it’s cross-onshore and the energy is a hefty 671—too much push with bad winds. By Sunday afternoon, it backs off to 4ft and cleans up, but it’s still only average.
Monday is messy with cross-shore winds. Nothing worth chasing. Tuesday, though, is flat—glassy and calm, but the swell is tiny, only 2ft, with weak energy around 79. Surfable if you’re desperate, but mostly it’s a bumpy, flat day. Wednesday morning stays small and clean, glassy even, but still just 2ft.
Now, the good stuff. Thursday the 24th, that morning is glassy with a south swell at 3ft, 10-second period, and energy at 228. Clean, but small. The real gem is Friday morning, the 25th. Clear skies, glassy, with a 4ft south swell at a solid 12-second period, and energy at 484. That’s proper groundswell direction, clean as a whistle, and for this point, that’s the standout of the whole forecast. Water temp is sitting at 73°, which is a touch warmer than normal for mid-September—a nice little bonus.
The weekend isn’t bad either. Saturday the 26th has some of that south swell, and the afternoon turns cross-off and clean, with 3ft at 12 seconds, energy at 289. Sunday morning is glassy too, but the swell is smaller at 2ft and from the east—less ideal. Then Monday the 28th brings it back: 5ft south swell at 9 seconds in the morning, light cross-off winds, energy at 551. That’s a solid, clean session, though the period shortens a bit. That’s your second-best window.
After that, it fades again. Tuesday the 29th has cross-onshore issues, but Wednesday the 30th—the last real day worth paddling out—is glassy in the morning with a clean 4ft south swell at 11 seconds. Energy at 394, clean faces. If you can get out early, that’s a cracker.
One thing to remember: this spot is “very consistent” but also “fairly exposed,” and crowds can show up sometimes. When it’s clean and the swell is from the south, it lines up perfectly. But a lot of this run is too small or too messy. The two standouts are Friday the 25th morning and Monday the 28th morning—those are your best bets. The longer-range stuff, like Wednesday the 30th, is promising but less certain, so don’t bet the farm on it yet.
All in all, it’s not a total dud, but it’s far from firing. You’ll get a few clean sessions if you’re patient, but there’s a lot of wind and chop in between. Keep your eyes on those south swells with light winds, and you’ll find some fun waves.
Rusty.

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.
