The Lowdown
Alright, let's break it down. The forecast for Praia Cardoso is a two-part story: a solid start to the second week of August, then a long stretch of nothing. We've got a proper Southern Hemi groundswell coming in, but it's going to take a few days to get clean. The first few days are a total loss, with strong onshore winds and rain messing everything up. From Saturday the 10th, the swell is up, but the wind is junk from the southwest, making it choppy and cross-onshore. The wave energy is moderate (3935) on Monday morning, but it's not surfable.
Then the magic happens. Tuesday, August 11th, is the one. The wind dies right out, switching to a light northwesterly in the morning, then a light northeasterly in the afternoon, giving us a clean, cross-off breeze. The swell holds at 7 ft from the south, with a 12-second period – proper groundswell with some punch. The combined energy is solid (1269 and 1236). This is proper, clean, powerful surf for experienced surfers. The water temp is about average for the time of year.
Following that, Thursday, August 13th, is another gem. The morning is a bit gusty, but the afternoon turns glassy. With a light northeasterly breeze and the swell at 6 ft from the south with a 14-second period, it's going to be buttery smooth. The energy is up (1315) and it's another one for the experienced crew.
After that, the swell lingers but the wind gets messy again through the 14th and 15th. Saturday the 15th morning has a clean 5 ft south swell with a light northeasterly, offering a solid option for the less confident.
Then we hit a wall. From Sunday, August 16th, the energy drops out completely. The swell goes tiny and the period gets short, with a lot of onshore wind. We’re looking at a solid 8-day stretch of flat, poor conditions from the 16th through to the 23rd. The energy drops to 3-digit and then 2-digit numbers, basically nothing. The morning of Friday, August 21st, shows a brief 5 ft south-southwest swell with a short 8-second period, and with glassy conditions it might offer a tiny window for a longboard, but it's a long shot.
Best bet? Get on Tuesday the 11th and Thursday the 13th. That's the real deal.
