The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for Praia das Macas.
Honestly, it’s a pretty bleak run for the next couple of weeks. We’ve got a solid gap right at the start with no surf worth paddling out for. The first bit of hope doesn’t show up until Tuesday the 28th of July, and even then it’s a one-morning window. After that, it’s back to the waiting game with another long stretch of nothing until the very start of August.
The only real standout in this whole 16-day window is the morning of Tuesday, the 28th of July. We’ve got a 6ft swell rolling in from the NNW with a 9-second period, pushing a moderate combined energy of 440. The wind is going to be glassy – dead calm – which is a massive plus for clean conditions. The water temp is sitting at 69°, which is pretty much bang on average for this time of year, so no surprises there. The catch? The swell direction is NNW but the optimum for this break is from the NW, so it’s a little off. Still, for a beginner-friendly spot that’s consistent, a morning with zero wind and some chest-high waves is about as good as it gets around here. Keep in mind that crowds are possible, so get in early.
The rest of the period is a write-off. The wind is mostly cross-onshore or onshore, often fresh, and the wave quality stays poor. Even when the swell size picks up later in the first week of August, the wind chops it up something shocking. Unless you’re a kite surfer looking for some breeze, there’s not much for a paddle surfer to get excited about.
Rusty.
