The Lowdown
Alright folks, Rusty here with the long-range look for our stretch of coast.
To be straight with you, the next week and a half is a bit of a slow burn. We’ve got a real flat spell through the first several days, with tiny, weak energy and mostly poor conditions. The wait is on for the real action.
The first standout to put a date on is Tuesday, August 25th. The morning session at Praia Cardoso is looking like the best bet in the whole window. We’ve got a solid 7ft groundswell, rolling in from the S with a long 12-second period, packing a lot of punch – the combined energy is strong at 1367. The real kicker is the wind: clean and cross-offshore from the NNE. This is going to produce excellent, well-shaped waves for experienced surfers. The water is sitting at 64°, which is about average for this time of year. This is the one to circle.
After that, we ease off a bit. Wednesday, August 26th morning offers a smaller, more mellow option. The swell drops to 4ft from the S, but with glassy conditions from the NNW and a light wind, it’ll be clean and fun for a wider range of surfers. The energy is moderate at 298.
Looking further out, there’s a promising pulse building for the very end of the month. Monday, August 31st morning is shaping up as another potential highlight. The forecast shows an 8ft S swell with a long 14-second period, ramping up the energy to a very strong 2698, and the wind is offshore from the NNW. This is expert territory again, but the conditions are setup for clean, powerful waves. Keep an eye on this one, as it’s a long way out.
There are a few other days with marginal waves, like the 23rd and 24th, but the wind and tide conditions are questionable, so I’d hold off for the cleaner windows.
Stay patient, and be ready for that 25th call.
Rusty.

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.
