The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for the stretch ahead. I'm going to be straight with you – it's a tough run for Praia das Macas. The whole 16-day window is a bit of a struggle, with cross-onshore winds and a lot of sloppy, choppy conditions. The swell energy is mostly moderate, so nothing to write home about from that perspective. The water temp is sitting at 67°F, which is about 1°F cooler than normal for this time of year, so pretty average.

We kick off on Wednesday, August 5th, with a small 2ft NW swell and a 9-second period, but the moderate cross-onshore breeze from the NNW is making it a messy morning. The afternoon doesn't get any better. Thursday, August 6th, sees the swell bump up a little to 4ft to 5ft from the NNW, but the wind picks up to a fresh 19 mph, making it lumpy and poor. Friday the 7th is more of the same with 4ft NNW swell and cross-on wind. Saturday and Sunday (August 8th and 9th) drop back to tiny 2ft to 3ft waves, still cross-onshore and choppy.

The first week of August is a write-off, folks. The winds just won't let up, and the swell is too small or too blown out to offer anything decent. It's a long gap of poor surf.

Now, things get a bit more interesting, but not really for us as surfers. Around Friday, August 14th, we see some proper energy... a 7ft to 8ft NNW swell rolling in, with the combined energy reaching strong levels. But the wind is howling from the North at 28 mph, with strong cross-onshore conditions making it an absolute mess. This is heavy, messy, and blown-out. For a beach break, that's going to be a disaster. Honestly, this setup looks more interesting for kite surfing than paddle surfing. The same goes for the weekend of August 15th and 16th, with that big but ugly swell.

The story doesn't change much as we close out the period. The strong winds persist, and the swell eventually drops back down to 3ft by the end of the week of August 19th, but it's still strong and messy. There simply isn't a single standout session in this forecast. The only break we have to look at is Praia das Macas, and it gets no love from the wind. It's a consistent spot, so it tends not to stay poor for long, but this run is a test of patience. Check back in a few days, the forecasts can change.

Rusty, signing off.
