The Lowdown

Alright folks, Rusty here, letting you know what's on the menu for the next couple of weeks at Praia das Macas. Gotta be straight with you – it's a tough stretch. The forecast is pretty grim for a solid week, with hardly any surf worth paddling for. There's a real gap, about a week of nothing, before we see a late pulse of energy, but even that comes with a catch.

Right now, the water is sitting at 65°, which is a bit colder than normal for this time of year, so you might want a spring suit for the first few days if you're even thinking about getting wet.

The first real chance of anything surfable doesn't show up until Wednesday morning, July 15th. We're looking at a tiny 1ft swell from the WNW with a period of 9 seconds, so pretty weak energy (42). The wind is glassy though, which is a major positive. It'll be surfable, but only just – it's really ordinary. For a beginner, it doesn't get much smaller than this, so it's a goer for a learner on a foamie, but don't expect much.

That's it for a while. The rest of the week and into the next is a write-off. We get a slight bump in size on the 18th and 19th, with the swell hitting 4ft to 5ft from the NNW, and the energy picks up to moderate – 238 and 250 on the 19th. But the wind is a cross-onshore mess, keeping conditions poor. It's just not worth the paddle out.

Then the 26th of July, a Sunday, things get interesting. The swell jumps to 5ft from the NW, breezing through to 6ft by the afternoon, with solid energy readings of 279 and 372. The period is short though, only 7 seconds, and the wind is onshore, so it's gonna be a messy, lumpy close-out. Not good for the paddle surfer, but this setup looks way more interesting for kite surfing than paddle surfing.

The one standout, and I mean the only one that gets a bit of a buzz, is the morning of Monday, July 27th. We get a chunky 7ft swell from the NNW with a period of 8 seconds, and the combined energy hits 523 – that's strong wave energy. The wind is a light cross-onshore from the WSW at 10 mph, which is very close to glassy. It's going to be a powerful, chunky day at the beach. However, at 7ft, it's over the 5ft mark, so it's not for beginners, and with the short period, it'll be a bit of a close-out freight train. The morning is the only chance before the wind kicks up. This is the best on offer, but it's a tricky one.

The rest of the 16-day window is pretty bleak. We're looking at a long blank run of poor surf. I'd keep an eye on the forecasts, though – it tends not to stay this poor for long.

Rusty.
