The Lowdown
Alright, folks, let's look at this 16-day stretch for Praia das Macas. I'm not gonna sugarcoat it – it's a long, frustrating grind of messy conditions. The swell shows up, but the wind is almost always ruining it. The only real bright spot, the only window that's worth paddling out for, is way out there on Tuesday, August 4th.
From Thursday the 23rd of July all the way through the end of the month, the wind is onshore or cross-onshore, and it's just choppy and lumpy. The swell gets some size, like Saturday the 25th with 5 ft from the NW (combined energy of 233 to 279), but with a fresh 19 mph cross-onshore, it's a blown-out mess. Sunday the 26th is even worse, with a 7 ft NNW swell (combined energy of 495) but a strong 22-25 mph cross-onshore wind. That's "strong cross-onshore and messy" territory, and it's not for beginners. The water temp is about 68°, which is pretty average for this time of year.
The first week of August is more of the same. The wind doesn't let up. It's cross and cross-on, day after day, with the swell dropping off. The energy is weak, often under 100. It's a tough run.
But then, on Tuesday, August 4th, we get a break. For the morning session, we see a 2 ft WSW swell with a period of 11 seconds. That's a bit of groundswell, and it's coming from the direction this spot likes. The key is the wind – it's a glassy 3 mph from the south. The combined energy is 123, so it's not a big day, but those waves will be clean. This is the only window in the whole 16 days where the conditions are described as "surfable waves but very ordinary conditions" and the wind is "glassy". It's a small day, but for a beginner spot, a clean 2 ft wave is perfect. The crowds are listed as "sometimes" here, so you might have a few others, but it's worth it.
The rest of that week after the 4th? The wind swings back to cross-onshore and it's all over again. The 5th and 6th of August have some NW swell, with energy up to 238, but the wind is just too strong and onshore.
So, the honest truth is this: the whole 16-day window is a bust for good surf, except for that one morning on Tuesday, August 4th. If you're a beginner, that's your window. Get down there early for the glassy conditions and some tiny, clean peelers. For everyone else? It's a frustrating wait. The forecasts can change, but based on what we have now, it's a tough one.
