The Lowdown
Alright folks, Rusty here. I’ve had a look at the charts for Praia das Macas, and to be honest, mate, it’s a bit of a tough stretch. The whole 16-day window is looking pretty grim. I’m not seeing a single standout that’s worth getting excited about.
The overall pattern is dominated by persistent cross-onshore winds, mainly from the NNW and N, which are just going to keep the surface messy and choppy. The swell is mostly small and weak, and what little energy we get is coming from the wrong direction for this spot. Praia das Macas needs swell from the NW to work well, but we’re seeing a lot of NNW and WNW energy, which just doesn’t line up right.
The water temperature is sitting at 68°F, which is pretty much bang on average for this time of year, so no surprises there.
Let’s run through the days. From Thursday, July 30th, we’ve got tiny, weak swell with that pesky cross-onshore wind. The combined energy is a measly 95, and the waves are just poor. This continues into Friday, July 31st, with the swell dropping even further and the wind picking up to 19 mph. Honestly, the setup looks more interesting for a kite surfer than a paddle surfer, with that strong cross-onshore breeze and lumpy conditions.
The weekend into next week doesn’t offer any relief. Saturday, August 1st, sees a bit more energy (combined energy of 178-220) but the period is short, around 5-7 seconds, and the wind is still ruining it. Every single day through to the end of the second week is marked by “poor surf conditions” and cross-onshore or onshore winds. The swell never gets above 5 ft, and when it’s at its biggest on Friday, August 14th, the wind is howling at 25 mph, making it a total mess.
There are simply no good options here. The whole forecast period is a blank run. For this area, when the wind doesn’t play ball and the swell direction is off, it tends to stay poor for a while. We’ll just have to keep an eye on it, but for now, I’d leave the boards in the shed.
Rusty.
