How late in the year (or early) can I start my brumation period? Would December be too late?

Brumation is a hibernation-like state that many temperate colubrids undergo during the winter. BPs do not "brumate".

If you are simply referring to the slight cool down often used to trigger breeding response and "kick start" your breeding season, then yes, that can start anytime. I normally start sometime in mid-late Novemeber, but anytime will do...
