The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, it’s a bit of a slow start for the first week and a half, I’m not gonna lie. The models are showing a pretty grim run of small, weak, and messy conditions for Praia Cardoso right through the opening days. We’re looking at a half-hearted south swell with a period under 10 seconds, and the wind is mostly cross-off or cross-on, which just isn’t doing us any favours. The combined energy is weak for most of this period, sitting below 100 (176) on the 30th, and then dropping to a paltry 20 on the 1st of August. It’s frustrating, but it’s just one of those quiet spells.
The first real glimmer of hope arrives on Wednesday the 5th of August, in the afternoon. The wind goes glassy, dead calm, with a south swell of 4 ft and a period of 9 seconds. The combined energy is moderate (399), and the waves are expected to be clean. It’s not a monster, but for a mellow, glassy session, it’s the best we’ve seen. The water temp is about 65°, pretty normal for this time of year.
Then we skip ahead to the real standout. If you’re an experienced surfer, you need to circle Monday the 10th of August. On the morning of the 10th, we get a solid 7 ft south swell, with a period of 12 seconds. The combined energy is a strong 1462, and the wind is light and offshore from the west. That’s a proper groundswell pushing in. For the crew at Praia Cardoso, this is the big one. It’s a fair bit of juice, so this is really for the experienced crowd only. It’s a clean, powerful south swell setup.
Right after that, on Tuesday the 11th of August, we have another excellent morning. Glassy conditions again, with a 4 ft south swell, 11-second period, and moderate energy (543). That’s a much more manageable size for a good crew, with perfect conditions.
So, the call is simple. The first week is a write-off. The best on offer is the big morning on Monday the 10th, and the clean, glassy morning on Tuesday the 11th. Get out there if you can.
Rusty.

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.
