If you don't know, Mobafire posts the new champs on their front page at around 1:00pm pacific. Hope it helps!
Or you could just check the announcements page.
you could do that too
You know that this site also lists the Champion rotation for the following week on Monday right?
The Blu Equine
mobafire does it a little before LoL has their announcement up i believe (don't ask me how).
