The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the table for Praia das Macas over the next couple of weeks.
To be straight with you, the next week and a half is looking pretty grim. It's a long, dry spell with hardly anything worth paddling out for. The wave energy is mostly weak, with values like 149, 150, down to 62 in the coming days, nothing to get excited about. The winds are either onshore or cross-onshore, keeping the ocean messy and uninviting. For a beginner break, even the small stuff is being blown out.
Now, the one bright spot – and I mean the *only* one – shows up on the morning of Tuesday, 28 July. That morning, the wind swings around to the southeast at just 3 mph, and it's glassy. Absolute glass. The swell is a clean 5 ft from the NNW, with a period of 8 seconds, and the combined energy is a moderate 348. The water temp is sitting at 69°, which is about average for this time of year, so no surprises there. This is your window. It's a small, beginner-friendly spot, so that 5 ft will be punchy but manageable. The catch? Crowds are sometimes a thing here, so get out early to grab a few clean ones before the wind shifts and the afternoon onshore kicks in.
After that glassy morning, it's back to the grind. The onshore winds return, and the whole thing just fades away. The next week, from 29 July right through to 5 August, it's all poor surf conditions – cross-onshore winds, choppy water, and lumpy, messy waves. Swell energy drops to 88, 76, 69, even 42 at one point. The wave heights are tiny, rarely cracking 2 ft, and the periods are all over the place, but nothing that's going to make you miss work. The weekend of 2-3 August sees a bit of a bump in height to 5 ft, but the wind is howling from the north at 19-25 mph, making it a rough, blown-out mess. That's more for the kite surfers than anyone with a paddle.
So, in short: it's a long, quiet stretch. The only real chance for a surf is that Tuesday morning, 28 July. If you can get out, do it. Otherwise, the ocean is just not playing ball for the rest of the forecast. Stay patient, keep an eye on the charts – things can change.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia das Macas may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
