When does it start to get "cold" in the Black Canyon

I'm hoping to head down the Black next weekend, but it might not work out. Does anyone know when things start getting cold over there? That is a pretty ambiguous question, so I am thinking more along the lines of 65 or higher on a good day for most of the climb? Is October a good season? November? Just curious if it doesn't work out.

when the sun goes down and you are nowhere near the top.

Fair enough. Was just wondering...we will find out I suppose!
