Table - best surf conditions forecast for Praia das Macas over the next 16 days.
Alright folks, Rusty here. Let’s have a honest look at what Praia das Macas has on offer over the next couple of weeks. I gotta be straight with you – this is a tough one. The forecast is pretty grim for a long stretch, and we’re not looking at any proper windows for a good paddle.
The pattern is dominated by small, weak swell and poor winds. For the first week and a half, from Wednesday the 8th right through until Monday the 13th, the wave energy is very weak, sitting between 27 and 145 on the energy scale, with heights barely breaking the 3 ft. The wind is mostly cross or cross-on, putting a chop on the surface. You won’t find a single rideable moment in there.
We finally get a tiny glimmer on Tuesday morning the 14th. For a brief moment, the wind goes glassy with a light westerly. The swell is tiny at 1 ft from the NNW, with next to no energy (42). The notes call it “surfable waves but very ordinary conditions.” Honestly, that’s the best we get in the whole outlook. For a beginner-friendly spot, that’s just about the only time a longboard might catch a knee-high ripple without getting blown to bits. That’s your only look.
After that, it gets worse again. The second week brings more size, but it’s all bad news. From Friday the 17th through to Wednesday the 22nd, the swell builds rapidly, hitting over 8 ft from the NNW by Monday the 20th. The combined energy jumps into the 400s, then 900s, and even over 1000 (strong to very strong energy). But the wind stays strong and cross-on from the north or NNW, 30 to 40 km/h (19 to 25 mph). That’s a messy, lumpy, blown-out mess. With that much wind and that much swell, and the fact this is a beach setup, the conditions are going to be more suited to kite surfing than a proper paddle session. It’s just not surfable for a traditional board.
So, to sum it up: there’s one morning, Tuesday July 14th, that might give you a tiny glassy crumble. The rest of the 16 days is either too small and choppy, or too big and blown out. It’s a lean run.
Rusty.
