Denver weather in December is cool, crispy with several sunny days. It's the time of year when you can still be outside to enjoy the fresh mountain breezes, but it's best to bundle up before you do.
During the day, the temperatures warm up to the mid-40s. At night, it will be below freezing most nights with even cooler temps as the month progresses. This time of year, most ski resorts have opened their doors and it's a fun time to head up to the mountains.
Read on for more tips on what to pack, average temps, and a few of my favorites things to do this month.
The Denver weather in December offers average highs around 46 degrees each day. The mornings start out cooler with temps increasing throughout the day. They begin to dip as the sun goes down.
At night, it's cool with lows that average 16 degrees. This is usually the overnight low and evenings will be in the mid to lower 30s.
You will also find a decent amount of snow this year with around 8 to 9 inches. It doesn't often fall all at once, so you will get an inch or two here and there. The sun often comes out throughout the days, so it will melt off quickly which means very little pile up of snow in December.

There are a few things you will need to bring with you to prepare for the Denver weather in December. Make sure to pack plenty of warm pants or jeans, heavy sweaters and flat shoes that don't slip. You can bring along running shoes or snow boots, both will do the trick.
In addition, you will want to bring along a heavy jacket and your gloves. I also recommend a scarf and hat if you plan to spend a lot of time outdoors. These are also great additions to your wardrobe for those colder Denver evenings.
It's also good to bring along a few items that you can layer. It isn't uncommon for the day to start off cool and end up warming up 20 degrees or more.
