The Lowdown
Right, pull up a stump and listen close. Rusty here, and I’ve been staring at the charts for Praia Cardoso. Let’s be straight with each other – for the next week and a half, it’s a tough watch. The pattern is soft and messy. There's a long, frustrating gap right from the start where there’s simply no quality surf to recommend.
The first glimmer of anything worthwhile doesn't show until Thursday, the 22nd of August, but even then, the swell is jumping up too fast with a strong onshore wind. The swell energy climbs from a weak 258 (moderate) on Friday the 21st to a much punchier 711 (strong) by Saturday the 22nd, but it’s all wind-affected.
The real standout, the only true standout in the whole 16-day window, lands on Sunday the 23rd of August. That morning, the swell is pumping at a solid 10ft from the SSW, with a period of 10 seconds. The combined energy is off the charts at 1704 (very strong). Now, here’s the catch – the data is clear that this is *too big* for this break. This is a big, powerful wave, and the wind is light and offshore. This is for experts only. Anyone else is going to be in a world of trouble. Still, if you’ve got the stones, that Sunday morning is the one.
After that, the energy backs off quickly. Monday the 24th is a jumbled mess, and we slide back into a long, quiet stretch. The water temp is sitting at a pretty average 65° for the time of year.
So, to sum it up for Praia Cardoso: there’s one epic day for the brave, and a whole lot of flat and choppy days to paddle through before and after. It’s a lean run, but that Sunday morning will make it all worth it for the right crew.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia Cardoso may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
