The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of onshore and cross-onshore winds, and the ocean’s going to be messy more often than not. If you’re desperate for a wave, you might find something small and gutless, but it’s going to be a fight against the chop. Honestly, for the first week, you’re better off finding something else to do. The swell energy is weak to moderate, but the wind is ruining any chance of clean waves. I’m talking readings like 154 and 161 on Saturday, which is just not worth the effort for the slop on offer. There’s a real gap here for the first several days where I wouldn’t even bother waxing up.
Come Monday the 3rd, things ease off a bit with a lighter breeze, but it’s still cross-shore, and the surf is dribbly – around 2ft to 3ft. Not good. That pattern holds through most of the week. We get a bit more juice around the 8th and 9th, with the swell pushing up towards 5ft, but that’s accompanied by a fresh 19 mph cross-onshore wind, so it’s going to be lumpy and blown-out. For a beginner spot like Praia das Macas, this is not your day. The energy does climb, but it’s all for nothing if it’s messy.
The only time you might want to look at the ocean is around the 14th and 15th, when the swell really kicks. We’re talking 6ft to 7ft from the NNW. But the wind is howling – 25 to 28 mph cross-onshore. That’s not surfable for most; it’s way too big and wild for the beginners, and for the experts, it’ll be a frothing, blown-out mess. The combined energy spikes on the 15th, but with that wind, it’s more of a kitesurfing setup than a paddle. This is a long way out, so it might change, but as it stands, I’d be looking elsewhere. All in all, a pretty bleak outlook. I’d keep the board in the car, but maybe not the wax. This is Rusty, signing off.
