The Lowdown
Alright, folks, Rusty here. Let’s get into it.
It’s a slow cooker for Praia Cardoso at the start. We’re looking at a week of waiting, to be honest. The first couple of days will leave you staring at a pretty flat ocean. There is some size on the 26th, but it’s messy with a fresh cross-offshore breeze, and it’s not the clean, organised swell we want. You’ll get some head-high waves out there, but they’ll be hard work. The water temp is sitting around 64°F, which is just about average for this time of year, nothing crazy. After that, it drops out again. The 27th and 28th are junk, with the wind howling on the Thursday afternoon and the swell fading fast. From the 29th through the 31st, it’s a real test of patience – tiny, weak swells with poor conditions. Save your energy.
Now, let’s talk about the first real standout. It’s on Monday, September 2nd. That morning, the ocean finally wakes up. We’ve got a solid 7ft of south-southeast groundswell pushing through at a nice 9 seconds, and the energy jumps to 1345 in the combined readings – that’s a serious pulse of power. The wind is a light offshore from the NNW, and it’s clean. This is an excellent window for experienced surfers. Praia Cardoso is exposed to the south, so this is exactly what we need. This is the pick of the whole run, no doubt. The 7ft size is proper, the wind is right, and it should be firing.
The days around it have potential but are let down by the wind. The 1st of September gets to a similar size, but a cross-onshore breeze chops it all up, making it a mess. The afternoon of the 2nd stays clean but the swell backs off and an easterly cross-wind comes in. By the 3rd, it’s blown out again with a near gale. There’s a little glimmer on the 5th of September – a glassy morning with a 4ft south swell and a 10-second period. That would be a fun, clean day for everyone, but the energy is much more modest than that standout on the 2nd.
The second week gets quieter, with smaller, longer-period swells from the south and east. The 8th and 9th see that longer period, but the size is minimal and the wind is up again. It all fizzles out towards the end of the window. So, if you can wait, the morning of Monday, September 2nd, is your day. It’s the clear winner.
Remember, this is a beach break, and a longer-period swell like we see later in the period can sometimes close it out a bit. But for that early September window, with that offshore wind, it’s going to be worth the paddle.
Rusty.

Information about the Praia Cardoso Surf forecast
The above surf forecast table for Praia Cardoso provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Cardoso can be found by selecting the local surf guide option on the grey menu. Our Praia Cardoso surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
