The Lowdown
Alright folks, let’s see what Praia do Porto has in store for us over the next couple of weeks. I’m Rusty, and I’ve been looking at the numbers.
First off, we’ve got a bit of a rough patch to start. The beginning of this forecast period is a real write-off. The wind is just howling onshore or cross-onshore, and the wave quality is poor. We’re talking Wednesday the 26th through to the end of the first week, with a few days of useless, choppy conditions. You’re better off waxing your board and waiting for the next window.
The first real glimmer of hope comes on Saturday morning, the 29th of August. The wind finally swings offshore from the SW, and we get a clean window. The swell is a manageable 6 ft from the ENE, with a period of 8 seconds. The combined energy is moderate (404). It’s not pumping, but it’s clean, and that’s a win after the blowout. The afternoon gets a bit cross-off, but still rideable.
The standout session, the one you want to circle on the calendar, is Tuesday morning, the 1st of September. The conditions line up perfectly. We’ve got a 7 ft swell from the SSW, which is a solid size, but it’s paired with a clean, offshore SW breeze at 12 mph. The combined energy is strong (823). The waves will be well-shaped and powerful. Just be aware that at 7 ft, it’s starting to get a bit serious for the beginners. This is the best bet in the whole 16-day window, hands down.
Following that, we have a few more clean mornings. Wednesday the 2nd has a smaller 4 ft ENE swell with a light offshore, and Thursday the 3rd brings another nice pulse of 6 ft from the S, also with light offshore winds (803 combined energy). Those are both solid, clean options.
After that, the second week gets smaller and more ordinary. There are a few glassy moments on the 4th and 6th of September, with tiny waves, but nothing to get excited about.
Later in the second week, around the 10th of September, we see a bigger swell pulse of 8 ft from the SE. That’s expert territory, size-wise, and the wind is onshore, so it’s going to be a messy, closed-out mess. Not worth it for a paddle.
So, to sum it up: the first week is mostly a bust, but the mornings of the 1st, 2nd, and 3rd of September are your golden windows. The 1st is the pick of the litter. The water temperature is sitting at 65°F, which is basically normal for this time of year, so a spring suit will do you fine.
Rusty, signing off.
