Alright, I’m just gonna be real with you. Praia das Macas isn’t looking too flash right now.
There’s nothing worth riding at the start. The first time we see anything surfable is early Sunday, July 12th. You’re looking at 0.7m of NW swell, a 9-second period, and a clean cross-offshore breeze from the SSE. Wave energy is moderate (139). It’s small, but a beginner might get some fun little waves. That afternoon, it goes south again.
Monday July 13th morning is worse – tiny, messy, only 77 energy. Don’t bother.
Then we hit a real dry stretch. From Monday afternoon all the way to early Tuesday July 21st, nearly every session is cross-onshore, choppy, or just flat. A week or more of nothing good. It’s that kind of frustrating run where the beach just doesn’t deliver.
But then, on Tuesday July 21st morning, things line up. The wind goes glassy out of the ESE at only 5 km/h. Swell is 0.9m from the NNW with a period around 8 seconds. Wave energy at 162 (moderate). It’ll be clean, smooth, and the best conditions of the whole outlook. That morning is the standout window.
The swell jumps to 1.7m on Wednesday July 22nd from the NNW, period 9 seconds, energy strong at 485. But the wind comes onshore and choppy again, so that size gets messy. Probably too big for beginners anyway.
The rest of the second week just keeps the same story: building swell to 1.2m–1.6m from the NW/NNW, but wind stays cross-onshore at 25–35 km/h. Short periods (6-7 seconds) mean poor shape. Energy climbs, but the quality never does.
Bottom line: if you want to surf, that Tuesday July 21st morning is your window – clean, small, glassy. Everything else is blown out or flat. Praia das Macas can turn around, but this run looks grim.
