@Grissomknew has good knowledge. I was in Jeri and Paracuru last August and brought my prone stuff, but there was never enough swell to use it. On the flip side, the wind was on everyday in Jeri and it was a great spot to learn to parawing.
If you fly through São Paulo and do a stop-over that time of year, plenty of swell to prone there. If you want to maximize your time and charge hard, do a few days of towing with the Bertonesia Foil Club. Epic spot and very dialed in operation. You can find them on Instagram
