James...October in Denver is Heavenly!!! Warm 80's daytime and mild nights around 50 degrees. The days are sunny! I love Denver weather...I have lived here for 45 yrs. The fall in Denver is magical. The leaves are turning is it always nice and dry. It almost never rains in October. Now towards the end of the month you can get a snow storm. It will almost always freeze once before the end of October, which ruins my gardening. Then it goes right back to Sunny days and gradual cooling of days to the 70s by Thanksgiving. But...you can get snow any time. When it does snow, it will normally go right back to sunny days. Honestly... it kind of gets boring. But it is beautiful here in the fall. Colorado Springs I know it can be a bit cooler because the city is right up against the mountains. But...pick Denver!!! You will love it here!

TO: Wedding Thoughts

Well, you know this winter 2019-2020 has been extremely mild in Denver so this year is an anomaly from the normal. With that being said, NORMALLY it is still hot until about November 1st. Around November 1st, it starts getting cold and sometimes REALLY COLD when snowstorms begin to come through in November. In November, it is a mixture of mildly cold days and super cold days..
