It is a little early for the monsoon season, is it not?
Getting wet periodically does not hurt them. I range my birds, and they will get caught out, or decide to be out in the rain.
As dry as you are there, it was probably be good for them. That every day dry air will dry their feathers out.
Yes, it is a couple weeks early.

I've actually noticed that their feathers feel softer (once dry again) after they've taken a rain shower. That soft water must be as good for feathers as it is for human hair.
