The Lowdown
Alright, Rusty here. I’ve been staring at the charts for Praia das Macas, and I’ve got to be honest – it’s a rough run. The swell comes and goes, but the wind is a killer, and there’s nothing worth paddling out for.
The water’s sitting at about 66°, which is pretty normal for this time of year, so no surprises there.
Right from the start, it’s flat and weak. The first few days have tiny waves, barely 1ft, with poor wind and barely any energy. The combined swell energy is in the low double digits, like 43, which is just a whisper. Nothing to bother with.
Around the 20th of July, the swell starts to build, with waves up to 4ft and the energy climbing into the moderate range (168). But the wind is still onshore or cross-onshore from the NW, so it’s going to be choppy and messy. Not clean enough for a good session.
The biggest swell of the whole window hits on the 26th of July, with waves pushing 8ft and a ton of energy behind it (891). That’s a serious amount of water, but the wind is blowing straight onshore, and the report says "poor surf conditions." For a beginner break like this, that’s just too big and too ugly. Honestly, with that much wind and that size, you’d be better off rigging a kite than trying to paddle.
The second week stays lumpy, with waves between 6ft and 7ft and energy in the 400 to 800 range. It’s all chopped up by the wind. There’s no clean window, no offshore breeze, no standout day.
So, straight up: there are no good surf options in this 16-day window for Praia das Macas. The break is consistent, so it’s a bummer the conditions aren’t playing ball. But it never stays bad for long around here, and forecasts can change.
Rusty.
