The Lowdown
Howdy, Rusty here.
Let’s break down what Praia Cardoso is serving up over the next 16 days. The first real window to grab your board opens up Tuesday, August 25th.
Tuesday morning it’s a solid 7ft S swell, 12-second period, glassy with a light north wind barely 3 mph. Water temp around 64°F – about average for the season. The combined energy is strong (1290). That’s expert-level height, but clean and powerful. That morning is the best early call.
Tuesday arvo the wind swings ENE to 12 mph and it gets choppy cross-shore – not worth it.
Wednesday the 26th, early again, 8ft S swell, 14-second period, very long-period groundswell. Combined energy hits 2445. NNE wind at 9 mph, cross-off, clean. That’s another big one for the experienced crew.
Wednesday arvo trashed by 22 mph NE winds.
Thursday the 27th morning drops to 5ft, but winds are messy. By Friday the 28th it’s down to 2ft and weak – combined energy under 150. That flat spell stretches from Thursday arvo through to Monday the 31st. Only tiny bumps.
Tuesday September 1st picks up to 7ft SSW but onshore chop. Not clean.
Wednesday September 2nd morning shows 4ft SE with a cross-off NNE breeze at 12 mph – marginal.
Thursday September 3rd is glassy with 3ft SE but only mediocre.
The big standout to wait for: Friday September 4th arvo and Saturday September 5th morning. Forecast says 10ft S swell, 12-second period, cross-off wind. Combined energy over 2457. But that’s too huge for this spot, so only if you’re a pro. Saturday arvo drops to 8ft with lighter wind.
After that it’s mostly onshore junk through the rest of the run.
Your best bet? Tuesday and Wednesday mornings, August 25th and 26th. Big, clean, powerful S swells. Not for learners, but if you’ve got the skill, go get some.
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. 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.
