Aside from the hot, dry, summers, we can ride here all year long in Las Vegas. The best months tend to be from October to April when the weather is nice. For some reason, when it gets cooler here, I hear complain how cold it is. I remind them that since they are in their cars they do not know what cold and hot weather really is. I have rode my Kymco Agility 125 in December to work when the over night low as 26 degrees and it feels like 6 degrees on the bike. I have also rode when the temperature was 115 degrees out on my way to my class at six in the evening the summer time. At that time, my bike was my only means of transport until I got a car last year. I enjoy riding no matter what the weather is like. The weekend forecast here in Vegas calls for day time highs in the low to mid sixties which is normal for us for mid November. If we want to see snow, we head up to Mount Charleston which is 45 minutes from Las Vegas.
