The Lowdown
Alright, this is Rusty. I’m looking at the next 16 days for your local surf, and I’m calling it like I see it—there’s nothing good on offer. The entire window is a bust for any decent waves.
At Praia das Macas, the outlook is all “poor surf conditions” from start to finish. The wind is cross-onshore nearly every session, and most of the time it’s a moderate or fresh breeze, which means the water’s chopped up and lumpy. The swell energy builds at times, like 167 on the 2nd of August morning, but it’s all for nothing with that wind.
The water temp is around 20°, just about average for the season with an anomaly of -0.4°. No surprises there. Swell heights range from 1ft to 5ft, with the bigger stuff coming later in the period, but it’s all messy. Directions are mostly NW and NNW, which is what this break likes, but it doesn’t matter when the wind’s ruining it.
There’s a massive gap with no recommendations at all. This kind of blank run is normal for this spot when the wind patterns lock in like this. No wave is worth the paddle. Hang tight and check back—forecasts can turn around.
