Blast pretty much said it all, I lived there for 18 months, you can stay in Cumbuco or Taiba if you like waves. Taiba is another 30kms up the road so easy to get too. There is another popular spot for wave riding which is the Port of Pecem, the wind is sightly ofshore so perfect to ride the waves. Cumbuco is a village in expansion, there are a lot of koreans there due to the large developments being done in the area so language is not a problem, my take is, rent a self catering flat where you have the freedon to do what you want, there are loads of places like that so not problem to find, you can check Flat Shop Imobiliária - Imobiliária em Fortaleza, Casas, Apartamentos, Terrenos em Fortaleza, Compra, Venda, Locação de Imóveis. and talk to Adriana, she will sort you out, there is also Itaculpa (Itacupa, Tabuba Brasil em Caucaia/CE), this B&B is owned by a Spaniard called Sergio Pereira, he is a mean kiter and loves adventures, also has SUP available all the time. If you want a bid more class there is always Duro Beach hotel you can talk to Adrian or Chris, both top guys, the food there is brilliant and the also have a kite shop by the hotel (Durobeach | Home). You must try to get to Paracuru, top spot with flat water near the beach and some nice waves on the outside.
There are a lot of fun to be had, it will only depend on money and stamina...
if you need anymore info please drop me a pm.
Have fun!
