The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Praia das Macas, and honestly, it’s a bit of a tough stretch. The whole 16-day window is basically a write-off for any decent surf. We’ve got a long dry spell from now, all the way through to the afternoon of Tuesday, 5th of August, before we even see a flicker of possibility.
From Tuesday the 21st of July right through to the morning of Tuesday the 5th of August, every single session is labelled with poor surf conditions. The energy in the water never really gets its act together, and the wind is almost always cross or cross-onshore, chewing up any chance of a clean face. You’ll see bursts of moderate wave energy – like 509 (moderate) on Sunday the 26th of July morning, but it’s straight into a fresh cross-shore breeze, so it’s just lumpy garbage. The swell direction is swinging around from NNW to NW, which is the opposite of what this place needs – it wants a proper NW swell. The period is short too, mostly 6 to 8 seconds, so it’s all weak windswell, no grunt or shape.
There’s one tiny glimmer right at the end. On the morning of Wednesday, 5th of August, the wind finally drops to a light onshore breeze, and the swell picks up to 6ft from the NNW with a short 6-second period (combined energy 305 – moderate). The wave comment even calls it “marginal surf” with a score that’s the first non-zero of the whole run. For a break that is consistent and exposed, this is a poor showing. It says a lot that the one “marginal” day is our best shot. At a beach setup like this, with that short period and cross-onshore wind returning by the afternoon, it honestly looks more interesting for kite surfing than paddle surfing during the bigger, windier days in the middle of the run.
Water temp is sitting at a typical 69°F for the time of year, so no need for a thicker suit, but you won’t need it because you won’t be in the water long.
For this spot right now, wait and see. The forecasts can change, but this is a long, quiet run. Rusty signing off.
