The Lowdown

Alright folks, Rusty here. Let's have a look at what's coming down the line for Praia das Macas. Gotta be straight with you – it's a tough start. The next week and a half is looking pretty grim with onshore winds and messy conditions. The only real glimmer of hope is a window right at the very end of this 16-day run. So, don't get your hopes up until we're well into September.

We've got a big stretch of poor surf from now all the way through to around the 7th of September. The wind's just not playing ball, nearly always blowing from the cross-on or cross-shore directions, so it's going to be choppy and lumpy. There will be some decent swell pulses, especially around the 28th of August when a NW groundswell hits with a long period of 11 seconds, but with 18 mph cross-on winds, it's just a messy mess. The combined energy on the 28th morning hits 2005 (strong energy), but you wouldn't want to be out there. The water's about average for this time of year, sitting around 66.6°.

Finally, on Monday the 8th of September, things take a sharp turn. Tuesday morning the 8th looks like the standout. We've got a clean, clean forecast. Winds swing around to a light SSE at just 6 mph, blowing cross-offshore. That's the golden ticket. You'll see a clean 5.6ft groundswell rolling in from the west with a very long period of 15 seconds, packing a punch with moderate-to-strong energy (1527). This setup is excellent for experienced surfers. The waves will be well-shaped and powerful, perfect for a point break or reef set-up. Keep in mind that crowds are possible here at Praia das Macas.

Tuesday afternoon the 8th looks like the wind will turn cross-on and it'll get choppy again, so that Tuesday morning window is the one to circle on your calendar. Trust me, it's been a long wait, but that should be a proper session.
