The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Praia Cardoso over the next couple of weeks.
To be honest, the next few days are looking pretty flat and frustrating. We’ve got a long stretch of small, weak swell and tricky winds, so you’re not missing much. The water temp is sitting at 65.5°, which is pretty much bang on average for this time of year, so no surprises there.
The first real flash of hope doesn't come until Tuesday, August 4th. We see a bump in energy with a moderate 3.6 ft south swell pushing through, carrying a solid 332 units of wave energy. It’s not huge, but it’s a start. The problem is the wind is a light cross-shore, so it won’t be perfect, but it’s the first time we’ve got something to work with. The conditions are only marginal, so keep your expectations in check.
Things get a bit more interesting on the morning of Sunday, August 9th. That’s when we get a legit 6.9 ft swell from the south, with a long 14-second period. That’s groundswell energy, and it really fires up the bank with a massive 1830 units of energy. Winds are a gentle cross-shore, keeping it a bit lumpy, but the power is there. This is a big swell though, over 8 ft, so this is strictly for the experienced crew. The long period also means it could be a bit straight at this beach, so look for a bend or a rip to help you out.
Now, the true standout. You want to circle Monday, August 10th in the afternoon. The swell backs off just a touch to a still very solid 6.6 ft from the south, with a 14-second period. The energy is still pumping at 1572 units. But the magic is in the wind – it goes glassy. Absolutely dead calm. That’s the kind of rare treat that makes for epic, clean lines. The reports call it excellent for experienced surfers, and I’m not arguing. That’s the best window we’ve got, hands down. It’s going to be a session to remember.
Later in the window, on the 13th of August, there’s a big 7.9 ft south swell pushing through, but it’s being hammered by a strong 25 mph cross-offshore breeze. The wave energy is huge at 1785, but that wind is going to make it a real battle. That one is more for the die-hards or maybe even the kite crew, as it’s going to be blown out.
Overall, the first week is a write-off, but that Monday afternoon window on the 10th of August is the real deal. Don't miss it.

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. If you surf the same spot (Praia Cardoso) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
