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 ahead. The first proper surf worth paddling out for doesn't really show until the morning of Saturday, July 19th, and even then, it's a struggle. We've got a solid week of flat, wind-affected dribble from Wednesday, July 15th right through to Friday, July 18th, so don't even bother getting the wax out for that first week.
This spot, a beginner-friendly beach break, is exposed to the NW, and that's the direction we need to see. The water temp is sitting about average for this time of year, so no wetsuit drama there.
The whole 16-day window is a bit of a write-off, to be honest. The wind is nearly always cross-onshore, and the swell is almost always coming from the NNW, which is not the optimum direction. The combined swell energy is weak for most of the run, with only a few days tipping into moderate energy (203 on the 19th, 248 on the 20th, 589 on the 26th), but it's always accompanied by choppy, lumpy conditions.
The closest thing to a standout, if you can call it that, is Sunday, July 26th. The morning will see a 6.6 ft swell from the NNW, with the combined energy hitting a strong 589. That's a decent push of water, but it's coming with a short period of 8 seconds and a moderate cross-onshore breeze. The swell is just over the 5 ft mark, so it's starting to get a bit much for complete beginners, and the wind won't be doing it any favours. It'll be a messy, lumpy affair. For the more experienced crew, there might be a few closeouts, but it's not going to be pretty.
The rest of the month is a blur of similar conditions: more swell, but always with that cross-onshore wind messing it up. By the time we hit Wednesday, July 29th, the wind is howling at 25 mph, and the swell drops back to under 3 ft. That's kite-surfing territory, not paddle surfing. It's a pretty bleak outlook, but it's what we've got. For a spot that's usually consistent, this is a long, blank run.
Short Range ForecastMostly dry. Warm (max 21°C on Thu morning, min 18°C on Thu night). Winds increasing (calm on Tue night, fresh winds from the NNW by Fri afternoon). | Days 4-6 Weather SummaryMostly dry. Warm (max 20°C on Mon afternoon, min 18°C on Fri night).
