In the wild there may be, but from my own very limited experience it seems that molts come rather randomly in captive birds. In fact Auggie is just finishing a significant molt now. (Also a bird from South America now living in North America.)
I don't know what the normal time is supposed to be but when we got Tumbala (Sun-Conure) in July I think he was just finishing a molt. He is now showering me with fethers daily and has lots of new one coming in. Makes it hard to scratch his little head sometimes. We live in Michigan and it's really cold right now.
