The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. We’ve got a 16-day window for Praia das Macas, and honestly, the surf is just not cooperating. The whole period is a write-off for any kind of decent paddle surfing. The wind is mostly cross-onshore, the swell is small and messy, and the wave energy is weak. The poor surf conditions are a constant theme, and this is a spot that faces a real battle with the wind. For a beginner, this is a frustrating blank run, but it’s a normal reality for this beach when the wind is on it.
The first half of the outlook, from the 3rd of August right through to the 10th, is a complete dead zone. The swell is tiny, often under 3ft, with a short period around 8-9 seconds, and the combined energy is weak to moderate (73-304). The wind is a constant cross-onshore, making for a choppy, lumpy surface. The water temperature is about average for the time of year. There’s just nothing to get excited about, and definitely no standouts. The surf is poor all the way through to the 11th, with a light breeze on the 11th morning, but that’s just a tease.
The second week is a little more interesting, but still no good. From the 12th to the 18th, the swell picks up a touch, pushing to 5ft and 6ft, with the combined energy climbing into the 400s (292-478). This is moderate wave energy, but the wind is still a problem. It’s a fresh cross-onshore on the 14th and 15th, making it lumpy. The period is short (6-8 seconds), so you’re getting a weak, choppy wind swell, not a proper groundswell. The swell is mostly from the NW, which is the optimum direction for the spot, but it’s wasted. The setup here is a beach, so with the strong wind and poor surf quality, this looks more promising for kite surfing than paddle surfing. There’s nothing here worth paddling out for.
Rusty, signing off.
