G’day, Rusty here. Look, I’ve gotta be straight with you – for the next couple of weeks, the surf at Praia das Macas is a tough watch. The entire 16-day window has been a dud for decent waves. We’re looking at a blank run from now all the way through to Sunday the 12th of July before you could even call it marginal, and even then, it’s nothing to write home about.
For the first week, from Saturday the 4th right through to Saturday the 11th, the ocean’s just been a mess. Mixed-up, short-period slop, mostly from the NNW and NW, but it’s all being clobbered by cross-onshore breezes. Swell heights are tiny, mostly around 1.0 ft to 3 ft, with weak wave energy (30 to 190 in the combined energy reading). The water temp is sitting at 66°, which is about normal for this time of year, so no complaints there, but the quality is just poor – choppy, lumpy, and no real push.
The first tiny flicker of something happens on Sunday the 12th of July in the morning. We get a pulse of 4 ft swell from the NW, with a period of 9 seconds and a jump in combined energy to 291. That’s moderate energy for a moment, but it’s still cross-onshore with a light breeze, and the conditions are described as marginal at best. By the afternoon, it’s already dropping.
Through the second week, from the 13th to the 19th of July, the story doesn’t change. Swell stays weak, under 3 ft most of the time, with more cross-onshore chop. By the last couple of days, the wind really cranks up to 22–28 mph from the N and NNW, pushing messy, lumpy 5 ft to 6 ft swell through. That’s messy, strong wind, with moderate to strong wave energy (up to 297). Honestly, with that much wind and poor surf quality, the setup at this beach-and-reef spot looks more interesting for kite surfing than paddle surfing. Beginners should steer clear of anything over 5 ft, and that swell is rough.
There’s simply no standout, no clean day, no good window. It’s a quiet, frustrating stretch – the kind where you leave the boards in the car and go for a coffee instead.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
