The Lowdown
Alright folks, Rusty here. Let's look at what the next couple of weeks have in store for Praia das Macas. The short story is, this is a tough run. We are starting out with a blank, no surf to speak of right now, and it’s going to be a long wait for anything close to good. The water temp is sitting at 69°, which is pretty normal for this time of year, nothing wild there.
Look, the first week or more is just a write-off. We’ve got a stretch from the 26th of July right through to at least the 10th of August where the score is never above a 2. The wind is almost always a problem - constant cross-onshore and onshore slop. Even when we get some size, like on the 5th and 6th of August with swell pushing 7ft to 8ft from the NNW, the wind is up and the conditions are blown out. On the 6th of August, the combined energy climbs to 689 to 728 (moderate to strong energy), but it’s all messy. You’d get more fun out of a kite than a surfboard on those days.
Then things get properly heavy and out of control. By the 8th and 9th of August, the swell is a solid 8ft to 10ft from the NNW, with a period of 9 to 11 seconds. That’s expert territory, and the combined energy hits 1678 to 1905 (strong to very strong wave energy). But before you get excited, the wind is a strong breeze to near gale force, all cross-onshore. It’s going to be a washing machine out there, absolutely messy.
Honestly, the only semi-interesting window is Monday the 27th of July. You get a 4ft swell from the NNW, and the morning is glassy with a slight air. The score isn't great, but glass is glass. If you are a beginner and you absolutely have to get wet, that’s your one chance, but don’t expect much. There’s also a brief moment on Tuesday the 28th of July morning where you have a 4ft swell from the NNW with a 10-second period and light cross-onshore wind (wave energy 327), but it’s still marginal. After that, it’s a long stretch of poor to zero recommendations until the end of the forecast period.
There are no standouts. Truthfully, for this region, a blank run like this isn't that unusual. Don't hold your breath.
Stay safe out there.
