The Lowdown
Hey, Rusty here. Let’s break down Praia Cardoso in feet and miles per hour.
To start, it’s a slow window. The first real chance of anything worth paddling for isn’t until Saturday, August 23rd, and even then it’s a waiting game. The first week is pretty flat and weak, with the swell staying small and the wind not doing us any favors. The little bump on Saturday the 15th was a 5ft south swell, but with a cross breeze and choppy surface, it was mostly a wash. From there, it’s a long stretch of tiny surf with poor conditions until Thursday the 20th, when a bit of energy picks up but the wind stays too strong to clean it up.
Now for the highlights. Saturday morning the 23rd is a beast – a solid 10ft swell from the SSW with an 11-second period. That’s serious power, with combined energy reading 4228. That’s for experts only – waves over 8ft are no joke. The wind will be moderate cross-shore, so it won’t be perfect, but the size and power make it a standout for the brave. The afternoon shifts onshore, so the morning is the call.
But the real gem lands on Tuesday, August 25th, in the morning. That’s a 7ft south groundswell with a very long 12-second period – that’s prime. And the wind? Glassy, dead calm. That is a dream session. Clean lines, no chop, just you and the ocean. The water temp is about 65°, which is average for this time of year, so a 4/3mm wetsuit will be fine. If you can get out there, that’s the one to aim for.
After that, the swell drops off. Wednesday the 26th has some 5ft swell, but the wind picks up, making it average. By Thursday the 27th, it’s back to weak stuff.
So here’s the plan: forget the first week. Saturday 23rd morning for the big, expert-heavy stuff, and Tuesday 25th morning for the clean, glassy perfection. The rest is a skip.
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.
