The Lowdown

Alright folks, Rusty here. Let's have a look at what Praia das Macas has cooking for us over the next couple of weeks.

Honestly, I'm looking at this forecast and feeling a bit bummed for you. We've got a long stretch of poor conditions ahead. The wind is nearly always from the wrong direction for this spot, coming cross-onshore or onshore most days, which is going to chop things up. It's not until Tuesday, the 25th, that we see a real window of opportunity.

The standout session, and really the only one worth paddling out for, is Tuesday morning, the 25th of August. We’re looking at a 5ft swell from the west, with a period of 7 seconds. The real kicker here is the wind – glassy conditions from the SSW at just 3 mph. That’s a major positive, meaning the surface will be clean. The combined swell energy is a modest 208, so it’s not going to be pumping, but for a beginner-friendly beach break, the clean conditions will make it fun and manageable. Expect crowds, as it's a consistent spot and a weekday won't stop the locals from getting in.

After that, it’s a real bummer. From Tuesday afternoon all the way through to the end of the period on the 7th of September, it's just poor surf conditions day after day. The winds are almost always onshore or cross-onshore, gusting up to 25 mph at times, which will create lumpy, messy, choppy waves. There’s a pulse of bigger swell around the 28th and 29th of August, with the combined energy climbing into the 900s and 1000s, but with a moderate to fresh cross-onshore wind, it’s going to be blown out. Even with a 7ft NW swell, the quality just won't be there.

Because of the persistent onshore winds, the setup here looks more interesting for kite surfing than paddle surfing during most of that second week.

So, to put it simply: if you can, hit it on Tuesday morning the 25th for a glassy session. After that, it’s a long wait with no real standouts until the 7th of September, which also looks poor.

Rusty.
