Alright folks, Rusty here. Let's have an honest look at what Praia das Macas is serving up over the next couple of weeks. I gotta be straight with you – it's a tough outlook. The first real surfable wave shows up on Sunday the 12th, but honestly, it's nothing to write home about. We've got a small 2ft swell from the west, but with a light cross-offshore breeze it cleans it up a bit. The water's sitting at 65°, about a degree and a half colder than usual for this time of year, so you'll want a spring suit. The combined energy is only 142, so it's weak. That Sunday morning window is the only half-decent moment for a while, and it's a beginner-friendly break, so a longboard or foamie would be the call. Crowds are possible here.
After that Sunday morning, things get grim. From Sunday afternoon all the way through to Tuesday the 14th, it's a mix of cross-on and onshore winds with tiny, weak swell. Then from Wednesday the 15th, the wind really picks up and stays nasty. By Friday the 18th, the swell starts to build – we're talking 6ft to 8ft from the NNW over the weekend, but the wind is a solid 22-25 mph cross-onshore. The combined energy jumps up to 355, then 800 by Sunday the 19th, but with that wind, it's just a messy, lumpy, blown-out mess. The waves are there, big and powerful, but the quality is zero. This is more of a kite-surfing setup than a paddle-surfing one.
The second week rolls in, and it doesn't get any kinder. From Monday the 20th through to the end of the forecast, we're stuck with persistent northerly cross-onshore winds and solid NNW swell, mostly between 6ft and 8ft. The energy gets massive – 1080 on Thursday the 23rd, and 1490 on Friday the 24th – but it's all cross-on junk. The period is a short 8-10 seconds, so it's windswell, not clean groundswell. For a beach break like this, that combination is a recipe for closeouts and choppy walls.
Honestly, there are no standouts here. The best on offer is that first Sunday morning (12th July) for a tiny, clean 2ft wave. After that, it's a two-week stretch of wind-affected, poor conditions. If you're desperate, you could paddle out on a big board when the wind eases a bit, but don't expect any magic. Forecasts can change, but as it stands, this is a blank run for the area.
Rusty.
