The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's get into it for Praia das Macas. The water is sittin' at a warm 70°, which is about what you'd expect for this time of year, no big anomaly.
Honestly, we're lookin' at a pretty grim stretch of days ahead. The whole 16-day window is a bit of a write-off, with no real standout surf to get excited about. The wind is mostly a problem, and the swell is just not cooperative. We've got a solid gap with no real recommendations, so let's just walk through what's happening.
The trouble starts right away. Saturday, July 25th, we've got a 6 ft NW swell with a short 7-second period, but a cross-on NNW wind at 16 mph is choppin' it all up. The combined energy is moderate (311), but it's just messy. That carries on through Sunday, July 26th, with a bigger 7 ft swell from the NNW, period still a short 7 seconds, energy jumpin' up to strong (443), but that fresh 22 mph cross-on wind will have it lookin' like a washing machine. Nothin' for the beginner crew here.
Monday, July 27th, the swell drops to 4 ft, wind lightens up a bit to 3 mph from the north, but it's still cross-on, and the forecast calls it marginal. The afternoon sees a shift to onshore wind from the west, which is a killer. Still nothin' to paddle for.
The rest of the month and into early August is a tough slog. The wind is relentless, mostly a moderate to fresh cross-onshore breeze from the NNW. Swell sizes yo-yo between 1 ft and 4 ft with weak energy values (between 49 and 288), but the poor wind conditions mean the surface will be lumpy, choppy, or rippled. It's a lot of "poor surf conditions" in the data, and I'm not gonna sugarcoat it.
There's a flicker of hope on Tuesday, August 4th. The morning shows a 4 ft WNW swell with a longer 9-second period, the wind is a light cross-on from the NNW at just 6 mph, and the energy is moderate (276). The forecast calls it marginal, but that light wind could make it the cleanest wave of the whole period. It's not a standout, but it's the best of a bad bunch. The afternoon stays clean-ish with an onshore wind, but the swell energy jumps to 422.
Then the wind cranks back up. Wednesday, August 5th, has a solid 7 ft to 7 ft NW swell with a 10-second period, energy is very strong (754-783), but it's cross-on with a moderate to fresh breeze, so it'll be a fast, lumpy mess. That wave size is gettin' a bit much for the beginners, too.
The final week from August 6th to 9th is just more of the same: strong winds, messy conditions, and swell dropping off. The combined energy stays moderate (107-453), but with strong cross-onshore winds, it's a no-go for a good paddle session. If you're a kite surfer, this setup might look interesting, but for a surfboard, it's a pass.
To sum it up, the only date that looks even slightly worth a look is the morning of Tuesday, August 4th, at Praia das Macas. The swell is small, but the wind will be light, makin' it the cleanest wave on offer. Everythin' else is blown out, choppy, or just plain weak. A tough forecast, mates. The beach is a consistent spot, so it won't stay this poor forever, but this run is a long one.
Rusty.
