The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
To be straight with you, the next sixteen days are a tough watch for surfing. The pattern is dominated by a persistent cross-onshore wind that just won’t let up, and the vast majority of the period gets written off with "poor surf conditions." We’re looking at a long stretch of lumpy, choppy, and generally uninviting water. The only real glimmer of hope is a single, brief window of glassy conditions, but even that is paired with small, weak swell.
The first surfable moment comes up on Tuesday the 4th of August. The morning is the standout, and really the only highlight in the whole outlook. Praia das Macas wakes up to a clear sky, glassy wind from the west at just 3 mph. That’s a major positive – it’ll be clean. The swell is small at 3ft from the WNW with a period of 9 seconds, and the combined energy is a modest 142 (moderate wave energy). The water temp is sitting at 68°, which is pretty much normal for this time of year. This is a beginner-friendly break, and that small, clean swell will be perfect for a longboard or a foamy. Keep in mind, crowds are possible here.
After that Tuesday morning window, it’s back to the grind. From Tuesday afternoon right through to the end of the 16-day window on the 18th of August, the wind stays cross-on or cross-onshore, mostly from the NNW. The wind picks up, with speeds regularly hitting 12 to 22 mph, making for choppy and lumpy conditions. The swell does push up over 5ft from Thursday the 6th onwards, and even hits 7ft on the morning of Saturday the 15th of August, but with the wind ripping straight across it, it’s just messy. While the combined energy climbs into the three and four-digit range (like 465 on the 17th of August), the wave quality is consistently rated as poor. With that much cross-onshore wind and a beach setup, this is honestly looking more interesting for kite surfing than paddle surfing. There’s a gap of nearly two weeks of poor conditions after that Tuesday morning, so don’t hold your breath.
