As well, the vast herds of wildebeest, zebra, some of their attendant predators, etc. will be in Tanzania, in the Serengeti (southern at that, possibly,) instead of in the Maasai Mara (the northern extension of the Serengeti ecosystem.)
OTOH, it will be less crowded, you will likely get some good views of local (non-migratory) critters, and it will not rain all day - most of the time, anyway. You may also see more younger animals. And you will not be bored... splendid views, lots to see... but definitely not what one would expect from July - September / October.
If I may ask further, where are you staying in the Mara / who is organising your safari in Kenya?
Thank you, JDiver, for this message as well as the Paddington Hilton suggestion. I am organizing this myself. I was in Kichwa Tembo September of 1998 and this time returning to Little Governor's Camp for my Honeymoon. As you imagine, I like to make it a unforgetable trip. My finance and I talked about it and willing to take our chances with the rain. As a resident of Seattle, a little rain does not bother us.
Thanks
