The Lowdown
Alright, you salty dogs. Rusty here, and I'm not gonna sugarcoat it. The next couple of weeks at Praia das Macas look like a total bummer.
We're staring down a pretty bleak run. From right now until about Thursday the 14th of August, the wind is going to be on our faces or from the side, mostly out of the NNW, and it's gonna be relentless. The surf will be choppy, lumpy, and just plain ugly. Even when there's a bit of energy in the water, it'll be blown apart.
For a spot that's normally good for beginners, this period is a washout. You're looking at small, messy waves.
We see a pulse of longer period swell around the 7th of August, coming in at 2 ft. from the NNW, with the combined energy sitting at 260 (strong). But with a 30 km/h cross-onshore wind, that window is totally slammed shut. For a beach break like this, it's going to be a mess – probably a better day for the kite surfers than us paddlers.
The most promising time is around the 14th and 15th of August. The swell bumps up to about 6 ft. from the NNW, but the period is short, around 6 to 7 seconds. The wind does let up a bit, going light and variable from the NNE or W. The forecasts are still calling it marginal, and the short period means the waves will be weak and mushy. You might find a few rideable ones, but it'll be a grind, not a classic.
So, bottom line: lock your longboard in the garage for the first 12 days or so. The second week is a faint hope, but nothing to get excited about. It's a rough patch, but that's the ocean for ya. Stay ready, but don't hold your breath.
Rusty.
