This can be a fun month if you like changing weather.
Here in Denver, we usually start out with 70s and lower 80s, see our first freeze by the 7th or 8th and our first snow by the 19th.
Highs usually are only in the 40s and 50s by Halloween.
We've had some Octobers that were high and dry and warm, and some that were cold and snowy.
A lot of people remember the blizzard of 1997 in Denver.
If it does snow this month, it is usually a wet and heavy snowfall with a lot of moisture content.
So what about where you live?
It is a transitional month for much of the country.
We usually see a small spike in severe weather across the midwest and the south as cold fronts start moving south out of Canada and the clash of airmasses being, much like we see in the spring.
