Praia Cardoso Surf Forecast and Surf Report

Alright, let’s get into it. This forecast for Praia Cardoso is a long, slow burn with a real payoff right at the tail end. The week kicks off with a lot of junk, so you’ll be sitting this one out for a while.

Starting off, the vibe is flat-out poor. The first few days, from Saturday the 12th through the early part of the following week, are all cross-onshore winds and choppy, messy surf. Swell heights hover around 4 ft to 6 ft, but the wind is just ruining it. The water temp is 62°, which is a couple of degrees colder than usual for this time of year – you’ll feel that bite in the air, too. Combined wave energy is moderate at best, clocking in around 237 to 543 (moderate energy). Nothing to get excited about.

Monday the 14th shows a flicker of hope with some light cross-shore wind and a longer-period swell (11 seconds), but it’s still just marginal – the tide or conditions aren’t quite right. The swell is 4 ft from the south, but it’s a bit of a tease.

Tuesday the 15th morning is actually the first slightly clean window, with light winds and a smaller 3 ft swell from the south, but the energy is weak (242). Some of you might paddle out for a longboard session, but it’s not what I’d call a standout.

Things really start to change around Thursday the 17th. Thursday morning is your first real highlight. We’ve got a clean 6 ft south swell with a solid 10-second period, and the wind is light and cross-offshore from the NNE. Combined energy jumps to 676 (moderate to strong). This is the kind of morning where the lineup might be a bit more inviting, especially if you’re a beginner-friendly intermediate – but 6 ft is getting towards the upper limit for beginners, so be mindful. The break is exposed to the south, and the optimum direction is S, so this is a good match.

Friday the 18th drops off again with stronger winds, so don’t get too excited.

Then we hit a really interesting stretch. Sunday the 20th brings glassy conditions in the morning with a 4 ft east swell – this is a great, clean session for the longboard or a fun mid-length. The wind is glass, and the crowd profile says “sometimes,” so you might have it to yourself if you’re early.

Monday the 21st is another clean morning, with a 5 ft east swell and light cross-offshore winds. Combined energy is 357 (moderate). Good, solid, fun waves.

Now for the big one. If you’re an experienced surfer, you want to circle September 23rd to 25th. This is where the ocean really wakes up. A massive, long-period south groundswell rolls in, but the heights are enormous: 12 ft on Wednesday the 23rd, peaking at 15 ft on Thursday the 24th with a 17-second period. The combined energy numbers are off the charts – 2167, 3610, even 11540 (very strong). This is expert-only territory. The wind is cross-offshore and clean, but at that size, Praia Cardoso is going to be a heavy, powerful beast. The swell direction is south and south-southeast, which matches the optimum of S perfectly. This is the best wave quality on offer for the whole forecast, but only for the crew with serious big-wave experience.

After that, we cool down. Saturday the 26th morning is excellent for the better surfers: a clean 5 ft swell from the SSE with a 13-second period and light offshore winds. This is a standout for the intermediate crew – the energy is still strong (692). But by the afternoon, the wind picks up and it’s back to being ordinary.

Sunday the 27th fades into small, choppy leftovers. A bit of a shame, but that’s the tail end.

The bottom line: The first week is mostly a write-off. The standout windows are Thursday the 17th morning, the glassy Sunday the 20th, and the clean Monday the 21st for the smaller-wave crew. For the big-wave hunters, the 23rd to 25th is where it’s at, but be ready for serious size. The long period of the swell (15-17 seconds) will make it better on a point or reef, but at a beach break like this, it might close out a bit. Still, it’s the most energy we’ll see.

Trust me, I’m Rusty, and I’ve seen this spot go from zero to hero in a week. This is one of those times.
