The Lowdown
Yo, Rusty here. Let’s talk Praia Cardoso. The next couple weeks are a rollercoaster—some absolute gems buried in between a lot of blown-out junk. Right now, we start off rough. Sunday the 9th is a no-go: a messy 8ft S swell with onshore wind at 19 mph, and combined energy sitting at 1091, so it’s got some push but it’s lumpy. Monday the 10th is still cross-shore and choppy. Tuesday the 11th afternoon is where it all changes—7ft S swell, 12 seconds, glassy. That’s a groundswell, clean and lined up. Combined energy ticks up to 1378, moderate but solid. The water’s 67°, a bit warmer than usual.
Wednesday the 12th morning stays clean with a light offshore breeze and 7ft S swell—great conditions. But the real highlight is Thursday the 13th. Thursday morning is glassy, 7ft S swell with a 14-second period, combined energy at 1754—strong energy for a beach break. Thursday afternoon is just as good with a 8ft S swell and offshore wind. Both sessions are clean and punchy. This is the best part of the whole outlook for intermediate to advanced surfers.
Friday the 14th starts to fade with cross-onshore wind, and by Saturday the 15th it’s lumpy again. Then we hit a flat spell from Monday the 17th through Thursday the 20th morning—combined energy drops to double digits, tiny surf, barely rideable. Thursday the 20th afternoon picks up a bit with 4ft SSW swell and glass, but it’s nothing to write home about. The following weekend, Friday the 21st through Sunday the 23rd, brings a bigger swell but it’s blown out again by strong winds. Monday the 24th morning looks glassy with a 5ft SSW swell, but the period is only 7 seconds, so it’s weaker windswell.
Bottom line: your window is Tuesday afternoon the 11th through Thursday the 13th. That’s where it’s at. Everything else is either flat or too windy to enjoy.
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.
