Weather in Riyadh in December
December in Riyadh is mild enough that walking is the default. This is a city-break month more than a sea-holiday month.
In Saudi Arabia, this is how Riyadh actually wears December, not how a country centroid would. Compared with July and January, December sits in the middle of Riyadh's year.

What to expect
Daytime
Mild afternoons in Riyadh are the prize in December. You can eat outside on the good days. You still want something for the breeze.
This is walking weather. Shade is useful, not essential the way it is in the hot months. A long outdoor day is a reasonable plan.
Rain
Rain is not the story in Riyadh 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
Sun protection
A layer for cooler evenings
