The Lowdown
Alright, Rusty here, let's talk about what's on the menu for Praia Cardoso.
The next week and a half is a bit of a mixed bag. We're looking at a solid run of south swell, but the wind is gonna be the main character for a lot of it. The water temp is sitting right where it should be for this time of year, so no surprises there.
We kick off with a tiny little pulse on Thursday morning, August 6th. Swell is a weak 2ft from the SSE with a period of 9 seconds – the combined energy is only 79, so it's pretty weak. The wind is light offshore from the NNW though, so it could be clean for a beginner to get a few knee-high ones. But honestly, it's not much to write home about.
Things pick up a bit on Friday, August 7th, but the wind howls from the SSW and S, making a mess of the 7ft to 7ft swell. It's a wind-swell, short period stuff, and it's going to be lumpy and cross-onshore. Not worth paddling out for.
We get a bit of a reprieve Saturday morning, August 8th. The swell is up to 8ft from the S, with a 13-second period – that's a proper groundswell with a lot of energy (1971). The wind is a cross-offshore from the NNE. It's a bit of a tricky call because the conditions are "marginal". The break is a beach break, so a long period swell like this might be a bit straight and fat. It's not the best we'll see, but it's a step up from the slop.
The middle of the next week is really where the standout sits. Mark your calendar for Wednesday morning, August 12th. The swell is a solid 7ft from the S, with a nice 12-second period, and the combined energy is a strong 1455. The wind is light and cross-offshore from the W. This is the one. The conditions are "excellent" for experienced surfers. At 7ft, it's getting up there, too big for beginners for sure, but for anyone with a bit of experience, this is going to be clean and powerful. This is the best session on offer.
After that, it drops off again. The rest of the second week is a lot of marginal conditions with cross and cross-onshore winds. The swell hangs around but the wind keeps it chopped up. Thursday morning, August 20th, has a glassy morning with a 4ft, 11-second SSE swell, so that could be a sneaky clean session but it's a step down.
Overall, the window is inconsistent. We have one clear standout on Wednesday the 12th. If you can get out that morning, you'll be in for a treat. The rest is a waiting game.
Rusty, signing off.
