The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Praia das Macas and, honestly, it’s a tough stretch. The next couple of weeks are looking pretty average, with a lot of poor conditions and cross-onshore winds messing things up. There’s a glimmer of hope right at the start of August, but you’re gonna have to be patient.
The swell energy is mostly moderate, hanging around in the 100 to 500 range, but it’s almost always paired with a messy wind. The water temperature is about average for this time of year, nothing unusual to report.
This weekend, Saturday the 25th and Sunday the 26th, is a write-off. Swell is up around 6 ft to 7 ft from the NW and NNW, but it’s short period (7 to 8 seconds) and the wind is a stiff cross-onshore. It’s just lumpy, choppy, and no fun. The combined energy is moderate (311 to 447), but it’s wasted.
Monday the 27th through to the end of the month is a real grind. Swell drops to 2 ft to 4 ft, still mostly from the NNW, and the wind stays cross-on or onshore. The energy drops right off, down to 103, and it’s just a bunch of small, messy waves. Not worth paddling out for.
Now, here’s your one genuine highlight. On Saturday morning, August 1st, the conditions finally line up. The swell is 4 ft from the WNW (10 seconds), which is a decent, long-period groundswell that’s right in the optimum direction for the break. The best part? The wind goes glassy. Absolutely flat calm. The wave comment says “glassy” and the combined energy is a moderate 312. This is your window. The swell is clean, the waves will have real shape, and it’s a beginner-friendly spot, so it won’t be too heavy. Just be aware that crowds are possible here.
After that one morning, it’s back to the grind. Sunday the 2nd and Monday the 3rd see a bump in swell to 6 ft-6 ft from the NNW, but the wind is back to a cross-onshore, making it choppy again. The rest of the week into August 9th is a mix of onshore winds and small, weak swell from the NNW. The period stays short, mostly 6 to 9 seconds, and the energy is usually below 300. Not much to get excited about.
So, the plan is simple. Save your energy for that Saturday morning, August 1st. It’s the only proper stand-out in the whole 16-day window. The rest is a waiting game.
Rusty.
