The Lowdown
Alright, grab a coffee and have a listen. I'm lookin' at the next couple of weeks here at Praia das Macas, and honestly, it's a bit of a rough stretch. The setup is exposed, and the winds are workin' against us for most of the run. The water temp is sittin' right around 68°, which is dead average for this time of year, so that's one thing you don't have to worry about.
We kick off Sunday the 2nd, and it's not pretty. We've got a tiny 2-foot swell from the west with a short period, and a cross-on breeze from the NNW at 12 mph. The energy is weak at 125, and the conditions are just choppy and messy. That's basically the story for the first week and a half. Monday the 3rd is a little smaller, Tuesday the 4th sees a slight bump to 3-foot from the WNW with a light onshore wind, but the energy is still low (142) and the quality is described as poor. The wind stays on the nose or cross-on for days, with the swell struggling to get past 3 feet and the period staying short. Thursday the 6th and Friday the 7th see the swell jump up to 6 - 6 feet from the NNW, but the wind is a fresh 19-22 mph cross-on, and the period is a terrible 6-8 seconds. The energy picks up a bit (406 on Friday morning), but it's lumpy, choppy, and just not for paddling. This kind of wind and size makes it look more interesting for a kite session than a surf session, to be honest.
We get a bit of a lull through the 9th and 10th, with the swell dropping back under 3 feet and the wind still howling. Then, on Wednesday the 12th, we finally see a little hope. The early morning session shows a clean window with a light cross-offshore breeze from the south at 6 mph. The swell is small, 2 to 3 feet from the WNW, and the energy is light (117), but it's the first time the report says "surfable waves" and "clean." It's not a standout, but it's the best we've seen.
After that, the wind picks up again. Thursday the 13th has a bit more size (3 feet, energy 271) but the wind is on it. We see a bigger spike on the 15th and 16th, with swell hitting 6 to 7 feet from the NW and NNW, but the wind is strong, 25-28 mph cross-on, making it a total mess. The energy is strong (434 to 661) but it's for experts only, if anyone is crazy enough to paddle out. The period is short, 6-8 seconds, so it's just a wind-blown shambles.
So, the honest truth for you here: there's no standout day. The best shot at a wave is the very early morning of Wednesday the 12th, when the wind finally swings offshore and the conditions are clean, even if the swell is small. Everything else is a battle against the wind. If you're not desperate, maybe give it a miss until the forecasts change, because it's a long stretch of poor surf.
