Unfortunately, one of the strongest relationships between El Nino and rainfall occurs in Indonesia/Papua New Guinea, and so predictions favor drier than average conditions continuing into at least early 2016.  One resource for seaonal outlooks for your region is available on the IRI page:

With that said, no climate prediction is ever guaranteed (100% chance).
