getting best exchange rate for maximum gain for Indian rupee?

I wish to transfer 1000USD to my US bank account from my Indian bank account(where the funds are in Indian Rupees). How can I find when the rupee is strong(or 1USD = 40something INR) so that I can do it to get the maximum benefit out of my Indian rupee? Today, 1USD = 48INR. How can I know when 1USD = 41 or 42INR. Is there a site's mailing list I can subscribe to for such news? Can someone please advise? Thanks

1. Banks do the best exchange rate. Rates are often published in the New York Times.
