October is when fall finally shows up in Las Vegas. We’ll get some cooler days in September, but it will be much more consistent in October. With that said, there will still be some hot days in October if there is a heatwave.
It’s also a great time to visit (as long as you avoid any large events or conferences) to get good prices on hotels.
