The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for our local stretch.
Right off the bat, I gotta be straight with you – it’s a bit of a rough patch ahead. We're looking at nearly a week of pretty average conditions before anything decent pops up. The water is sitting at 70°, which is pretty much what you'd expect for this time of year, nothing unusual there.
From Friday the 24th through to Saturday the 1st of August, it’s a write-off. We've got solid swell coming in, with wave energy in the moderate range (114 to 321), but the wind is just ruining it. It's mostly a cross-onshore breeze, and on the 26th and 27th it picks up into a fresh breeze creating lumpy, choppy conditions. A couple of mornings, like the 27th, we get a bit of a reprieve with lighter wind, but it's still cross-onshore and the wave comment just says "poor surf conditions". There's nothing to get excited about.
The real story here is a single window of hope. It comes on Sunday morning, the 2nd of August. This is the standout. We’ll have a clean 4ft NW groundswell with a decent 10-second period. The combined energy is a solid 307, so there's some punch. But the big tick is the wind – a light SSE breeze going cross-offshore. The report says "clean", and for Praia das Macas, that's as good as it gets. This is the one session to pencil in. Keep in mind, the swell direction is NW, right in the goldilocks zone for this spot. The winds will be light, so the crowds might be out, but it'll be worth it for the clean faces.
After that brief moment of glory, we slide back into the poor stuff. From Sunday afternoon the 2nd through to the 8th of August, it’s back to cross-onshore winds and lumpy surf. The swell gets bigger, hitting over 7ft on the 3rd and 4th, and the wave energy jumps up to strong territory (over 600). But with a strong onshore breeze, it’s going to be a washing machine. Honestly, for a spot like this, that sort of wind and swell combo looks more interesting for the kite surfers than for us paddle guys.
So, to sum it up: you've got a long wait, but Sunday morning the 2nd of August is your shot. Gear up for that one.
Rusty.
