The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks at Praia das Macas.

Honestly, it's a tough stretch ahead. The first few days are a write-off. Tuesday the 25th through Thursday the 27th is just messy with onshore winds and weak, short-period windswell. The water is sittin' at 67°, which is a bit colder than normal for this time of year, so you'll want a decent spring suit.

We’ll see a bit of a pulse arrive on Friday morning the 28th. The swell is picking up to 8ft from the WNW, and the period stretches out to 11 seconds, giving it some real grunt. The combined energy is a solid 1474, which is strong. But the wind is a cross-shore N breeze at 12 mph, making it lumpy. The surf report calls it marginal, and honestly, with that size, it's pushing into expert territory if it's closing out. Not the cleanest, but it's the first real swell we've seen.

The pattern doesn't let up. Saturday the 29th and Sunday the 30th drop back down in size, but the wind stays on it, so it’s still choppy.

Now, here's the one that has my attention. It's a long way out, but Monday the 7th of September morning has a real beast showing up. We're looking at an 8ft groundswell from the NW, with a very long period of 12 seconds. The combined energy is a massive 1878 – that’s pumping. The wind is forecast to be a cross-shore N breeze at 19 mph, so it’ll be lumpy again. The report calls it marginal. At that size and period, it’s going to be a proper expert-only wave, likely closing out across the beach. It's a promise of power, but it’s a wild card.

Other than that, the rest of the outlook is a grind of onshore winds and messy conditions. The 8th of September has a similar setup but a touch smaller, and the 9th of September brings a choppy 7ft NW swell. There's a lot of energy in the water (the 8th has 1635 combined energy in the afternoon), but the wind is just ruining it.

So, for the standouts: if you're a confident expert, Friday the 28th of August is your first chance to get on something solid, but don't expect perfection. The real highlight, if the forecasts hold, is the morning of Monday the 7th of September. That's a big, powerful groundswell but it's a long way off and the wind is a big question mark. It's a gamble.

Rusty.
