The Lowdown

G'day, Rusty here. Look, I've got to be straight with you – this is a tough outlook for Praia das Macas. We're looking at a full 16-day window, but honestly, there's nothing in the first two weeks that I'd even call a surf. It's a rough run.

The pattern starts off flat and stays that way for a long stretch. From Friday the 17th right through to Thursday the 30th of July, it's just a constant stream of "poor surf conditions." The swell is small and weak, with a combined energy that barely gets out of the double digits for the first week, hitting a moderate 158 on the 20th, but it's all junk. The wind is a relentless cross-onshore, blowing from the NNW and NW at 12 to 22 mph, making everything choppy and messy. There's a period of "fresh cross-onshore and lumpy" from the 25th onwards, which is just ugly. The water temperature is sitting at 67°F, which is about average for this time of year, so no surprises there.

The only real standout comes right at the very end of the forecast, on Friday the 31st of July. We get a proper pulse of swell – 12 ft from the NNW in the morning, dropping to 10 ft in the afternoon. The combined energy jumps to 1819 (strong to very strong wave energy), and the wind finally drops to 12 mph, still cross-on, but it's a "moderate cross-onshore." The wave comment even says "wind and tide favorable." But here's the kicker: at 12 ft, this is expert territory only. It's simply too big for beginners, and even for experienced surfers, it's a beast. The period is 9 seconds, so it's a wind swell, not a clean groundswell. For a beach break, that size with that wind will be a washing machine. Honestly, this setup looks more interesting for kite surfing than paddle surfing.

The following Saturday the 1st of August, it's back to strong cross-onshore winds and messy conditions with 10 ft to 8 ft sets. It's a no-go.

So, the bottom line? There's a huge gap of nearly two weeks with absolutely no recommendations. The only day with any potential is the 31st of July, and that's only for the brave and the expert. For everyone else, it's a write-off. Forecasts can change, but this one looks grim.

Rusty.
