Alright folks, Rusty here. Gotta be straight with you – this is a tough one for our stretch of coast. Looking at Praia das Macas, the whole 16-day window is a bit of a struggle. We start off Sunday the 5th with tiny, weak swell and a persistent cross-onshore breeze that's just messing things up. That onshore wind is pretty much a constant for the first two weeks, locking in choppy, lumpy conditions. The wave energy stays low for days, so there’s nothing worth paddling out for. This poor run keeps up right through to Saturday the 18th. There’s a build of swell mid-month, with some 7ft sets on Sunday the 12th, but it’s paired with a fresh 22 mph cross-onshore wind – that’s a washing machine, not a surfable wave. That kind of size with those winds is more of a kite-surfing setup than a paddle session.
But there’s a small window that saves the whole outlook. It’s gotta be Sunday morning the 19th of July. That morning, the wind flips to a light 3 mph from the NNE, making it glassy – total magic. We get a 6ft groundswell from the NNW at 8 seconds, with strong energy. It’s the only time in the whole forecast where the wind, swell, and energy come together. The water temp is 67°, which is bang on average for this time of year - no surprises there. The downside? This spot gets crowded sometimes, so expect company if the word gets out. But for beginners, 6ft is at the top end of comfortable – more for the experienced intermediate crowd. After that sunny morning window, the wind swings back onshore, and we’re back to slop for the final days of the outlook.
So, if you’re hanging on for a wave, your one real shot is the morning of Sunday the 19th at Praia das Macas. Get it early before the wind turns.
Rusty.
