The Lowdown
Alright, let’s get into it. The first call is for Wednesday morning at Praia do Aventureiro. There’s a clean, glassy start with a small 3ft south swell, and that long 10-second period is giving it a little push. The water temp is feeling about average for this time of year, which is normal. It’s not big, but the conditions are right – it’s a good one to get the wetsuit on for a few smooth ones.
The wind stays light but swings cross-shore in the afternoon, and the surf gets a bit churned up. Not worth the paddle then. Thursday morning is blown out by a cross-on wind, but the afternoon is a different story. That S swell holds at 3ft and the cross-off breeze cleans it right up. It’s a much better window, though it’s still on the smaller side.
Friday brings a bit more size, around 4ft, but the cross-on wind keeps it messy. The swell is starting to feel more powerful, though, with the energy jumping up. We see that building into Sunday, where the swell gets real – pushing 6ft in the morning, but the wind is straight onshore. That’s a mess. Then it jumps over 7ft in the afternoon with stronger onshore wind, so that whole day is a write-off unless you're an expert looking for a battle, and even then, you're fighting the wind.
The start of the following week stays onshore and bumpy. Monday’s not worth it. But things turn around Tuesday morning, with the wind dropping to glassy and a knee-to-waist high 4ft south swell rolling through. It’s clean and fun again, just like the start of the forecast. Wednesday the 16th looks like a proper pick, too. We’ve got a 5ft south swell in the morning with a cross-off wind keeping the face smooth, and then it backs off a touch in the afternoon with the wind turning offshore. That’s the standout window right there – clean, long-period energy, and the point should be reeling.
Now, here's where it gets interesting. The swell goes on a serious run. A big, long-period groundswell shows up on Thursday the 17th, hitting 5ft with a 16-second period. The energy reading is massive. But the wind is cross-on in the morning and then comes straight onshore in the afternoon, which ruins it. It’s a tease, seeing that much juice with nowhere to go with it.
Friday the 18th has a decent 4ft S swell but it stays a bit lumpy. Saturday the 19th drops back down to 3ft, but it's glassy in the morning and perfect for the point, just small. Sunday the 20th get super small, back down to 2ft. The surf gets pretty lean for a few days.
But then the outlook picks up again. Monday the 21st has a few fun ones, with a clean 2ft in the morning and a better 4ft in the afternoon, even if the direction shifts a bit. The real highlight, though, is Wednesday the 23rd. Clear skies, dead calm wind, and a 5ft east swell that’s reeling down the point. The period is short, but the conditions are perfect – it should be a ripper morning.
So, you’ve got two real standout windows: Wednesday the 16th for that clean, good-sized S swell, and Wednesday the 23rd for the biggest, cleanest waves of the period. The gap in between is small and messy, but those two mornings holding decent size with clean conditions are worth the wait. It’s a classic case of pick your moment, and those are the ones. The surf never fully dies, but it gets small and choppy for a stretch. Stick to the early morning windows for the best chance.
