What to expect
Daytime
Hot days in Las Vegas. Ruins, markets and hills are a morning job. Midday sightseeing is how people remember September for the wrong reason.
Nights stay warm. Air-con, if you can get it, is part of the brief. A jumper for September in Las Vegas is almost always a waste of bag space.
Rain
Rain is not the story in Las Vegas in September. 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.

What to pack
Sun protection
A layer for cooler evenings
