ACCEPTED ANSWER

Score 7

As in comments, "two months ago" or "the month before last" are common ways to phrase this. As also noted on comments, some folks will drop "the" from "the month before last." That's a pretty informal mode of speech, but bear in mind that there's another "month" implied in the phrase already "the month before last [month]."

ANSWER 2

Score 5

A late answer but you can say "penultimate".

ANSWER 3

Score 3

If you really need a single word, just give the name of the month.

ANSWER 4

Score 1

How about “ante-previous”? (I just made it up, but I believe that it makes sense.)
