The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Praia das Macas. Gotta be straight with you, the next 16 days are a bit of a mixed bag, and honestly, for a lot of it, you might be better off finding something else to do.
The first real chance of anything surfable doesn't pop up until Monday morning, July 27th. Up until then, it's a write-off – Thursday the 23rd through Sunday the 26th are all a mess of cross-on winds and lumpy conditions, with swell heights all over the place but zero quality. Just a look at the combined energy on Saturday the 25th (303) and Sunday (495) tells you there's power, but it's ugly power.
So, the standout window is Monday morning, July 27th. This is the only time in the whole run that things line up. We’ve got a 5 ft swell from the NNW, with a period of 8 seconds. The magic here is the wind. It's glassy, dead calm from the NNE at only 3 mph. That’s a major positive. The combined energy is a solid 287, so there's a decent push. For a beginner spot like this, the 5 ft swell is a great size – not too big, not too small. The water temperature is sitting at 68°, which is about average for the time of year, so no shocks there. You’ll likely have company as crowds are listed as "sometimes," so expect a few others with the same idea.
But that's where the good news ends. Monday afternoon the wind swings back onshore, and from Tuesday the 28th all the way through Friday, August 7th, it's back to the same story: cross-on winds, choppy, lumpy conditions. The swell keeps coming, with some big numbers on the energy scale – check out August 3rd with 370, and August 5th hitting a massive 723 and 650. But the wind is just relentless. By August 7th, we’re looking at 8 ft swell with 22 mph cross-on winds. The wave energy is through the roof (953), but for a beginner-friendly beach break, that’s way too big and messy. It's one for the experts only, and even then, the wind is going to trash it. Honestly, with that much wind and swell, this setup looks more interesting for kite surfing than paddle surfing.
So, to sum it up: you've got one real shot, and it's a brief one. Set your alarm for the 27th, get out there early, and enjoy the glass. After that, it's a long wait for a change in the weather.
Stay salty,
Rusty
