The Lowdown

Alright, let’s get into it. The next couple of weeks are a bit of a mixed bag, but there’s a window worth your time if you’re patient.

Right off the bat, things are looking pretty average at Praia das Macas. The water’s sitting around average for this time of year, nothing crazy. But the surf just isn’t there for the first week. From Sunday the 9th through the 16th, it’s all cross-onshore wind and small, weak swell. Sizes are mostly under 5 feet, with periods all over the place, mostly short. The energy in the water is weak to moderate at best – we’re seeing values like 132, 149, and even 312 on the 12th, but it’s all messy and chopped up. You’d be fighting an onshore bump for nothing. Honestly, it’s a good time to do something else.

The real story starts on Monday the 17th. That’s when things finally line up. The morning is still a bit iffy with a cross-shore wind, but the swell is building – 7ft from the NNW. The energy jumps up to 661, which is a solid, strong push. But the afternoon is the standout. The wind drops to glassy, dead calm. The swell holds at 7ft from the NNW with a 9-second period, and the energy is 680. That’s clean, powerful surf and it’s going to be worth the wait. This is the best day on offer, no doubt.

The setup is a beach break, so with that 7ft swell and a period around 9 seconds, it should have some punch. It’s not a giant day, but it’s got enough to be fun. The glassy conditions are the key. This is your window. After that, Tuesday the 18th still has some size in the morning – 6ft – but the cross-shore wind messes it up, and it deteriorates from there.

After that, it fades back into the same old story. The rest of the week and into the next one is mostly small, cross-onshore slop. The swell drops back under 5 feet, the winds pick up, and we’re back to choppy, uninviting conditions. There’s a little bump on the 21st and 22nd, but the wind is on it, so it’s not going to be clean.

So, plain and simple: if you’ve got a free afternoon on Monday the 17th, that’s your call. It’s the one true standout in a period that’s otherwise pretty flat and messy. The rest of the time, you’re better off checking the wind apps and hoping for a shift.

Rusty out.
