Weather in Monterrey in December
December in Monterrey is cool outdoor weather: usable if you dress for it, not a beach brief.
In Mexico, this is how Monterrey actually wears December, not how a country centroid would. Compared with June and January, December sits in the middle of Monterrey's year.

What to expect
Daytime
Cool days in Monterrey: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.
Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.
Rain
Rain is not the story in Monterrey in December. Pack for sun. A shower would be news, not a plan.
Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
A layer for cooler evenings
