The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the menu for Praia Cardoso over the next couple of weeks. Gotta be straight with you – it’s a bit of a mixed bag, and we’re starting with a real slow cooker.
Right off the bat, Monday the 31st of August is offering very little. The morning’s a write-off with a weak 2ft SSE swell and poor conditions. The afternoon, while it shows a pulse of energy with a 6ft easterly swell, it’s around 8 seconds and there’s moderate rain. It’s not our best window.
Tuesday the 1st of September looks blown out with strong onshore wind and a lumpy 7ft swell – honestly, that’s more of a kite-surfing setup than a paddle session for a beginner-friendly spot. Not worth chasing.
We finally get a clean chance on Wednesday morning, the 2nd of September. The wind goes light offshore from the west, cleaning up a solid 6ft SE swell. This is the standout early window. The waves will have some shape and the water’s a bit colder than average for the time of year at 63°F, but it’s doable. Crowds can be around here sometimes, so you might have some company.
Thursday the 3rd stays clean in the morning with a lighter 4ft SE swell and a longer 11-second period. It’s a good option for the beginner-friendly setup here, but it’s not as punchy as Wednesday.
After that, we hit a big gap. From Friday the 4th right through to the second week, the surf quality drops off hard. We’re looking at tiny, weak swells and cross-onshore winds. A few pulses show up around the 7th and 8th of September with 5ft to 6ft S and SSE swells, but the wind and chop just kill it. It’s marginal at best.
There is a curious little spike on the 15th of September – a very long period 18-second S swell, but it’s only 2ft. That’s a ghost swell. For a beach break like this, that kind of period makes it tricky and straight. Not a goer.
So, if you’ve got one window to paddle, make it Wednesday morning, September 2nd. That’s the pick of the fortnight.
Rusty.
