The Lowdown
Alright, Rusty here, and I’ve got the outlook for the next couple of weeks at Praia das Macas.
To be straight with you, it’s a pretty grim stretch for surfing at this spot. The first recommendations don’t even kick in until well into the run, and even then, it’s a tough sell. For the entire period, the conditions are mostly a write-off. The wind is almost always cross-onshore, and the wave height stays small for days, bouncing between a tiny 1ft and a mediocre 4ft for the first week. The combined swell energy is weak, hanging in the 28 to 75 range for a long time, with short-period, choppy waves. You’d be fighting a losing battle.
The water temp is sitting at 66°, which is about normal for this time of year, so no surprises there.
The only day that even flirts with being worth a look is Thursday, July 30th. The morning brings a bit more size at 5ft from the NNW, with a period of 7 seconds and a light breeze that might clean things up a touch. The combined energy bumps up to a moderate 227. Then the afternoon gets interesting: the wind swings around to the south at 12 mph, going cross-offshore, and it cleans up nicely. The wave height pushes up to 6ft from the NNW, with a decent 288 combined energy. The model calls it a marginal surf forecast, but with that clean wind, it’s the only window in the whole 16 days where you might get a few halfway decent waves. The swell is under 8ft, so it’s not just for experts, but at 6ft, it might be a bit too much for total beginners to feel comfortable. Crowds are possible here.
Other than that one afternoon, the rest of the run is a bust. The first week is a total dud, and the second week offers nothing better than lumpy, cross-onshore junk with wind speeds kicking up to 28 mph—more of a kite-surfing setup than a paddle session.
So, if you’re keen, mark the calendar for the afternoon of Thursday, July 30th. That’s your best bet, but it’s a long way off and I wouldn’t bet the house on it.
Rusty.
