What to Wear in Denver in December

Based on typical December conditions in Denver. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
December in Denver, Colorado, ushers in a true winter experience characterized by crisp, often sunny days and significantly cold nights. Expect average daytime temperatures to hover in the low to mid-40s°F (4-7°C), frequently dipping into the teens or low 20s°F (-10 to -5°C) after sunset. While snow is a common occurrence, Denver doesn't typically get continuous heavy snowfall; instead, you might encounter several light dustings or a few more substantial storms throughout the month. The high altitude means the sun can be quite intense, even on cold days, and the air tends to be very dry. Dressing for Denver in December requires a strategic approach focused on layering. Start with moisture-wicking base layers, such as thermal tops and bottoms, especially if you plan to be active outdoors. Add warm mid-layers like fleece jackets or wool sweaters for insulation. Your outermost layer should be a waterproof and windproof insulated coat – crucial for blocking the chill and any potential snow. Don't forget essential accessories: a warm hat, waterproof gloves, and a cozy scarf are non-negotiable. Footwear should consist of insulated, waterproof boots with good traction, perfect for navigating icy sidewalks or light snow. Sunglasses are also highly recommended due to the bright high-altitude sun reflecting off potential snow.
Curated Looks
Casual
Vest and Joggers
An olive puffer vest over a plaid flannel and grey joggers is the cool-clear casual combination that still looks considered. Black knee-high boots with joggers is the part that shouldn't work — but does.
Chic
Burgundy Quilted Combat
A burgundy quilted jacket over a black crewneck and cream maxi skirt is sharper than the forecast demands on a cool clear day. Black combat boots and a burgundy scarf land the look.
Cute
The Lilac Edit
Clear skies at 45–54°F let the quilted lilac vest take the lead over a Breton stripe and cream maxi. Patent thigh-high boots make the whole thing slightly more interesting than expected.
Cozy
Teddy and the Crewneck
A cream teddy coat over a black crewneck and fleece-lined leggings is warm without being heavy. A grey knit scarf worn loose over the coat is the only accessory it needs.
Sporty
Fleece and Burgundy Boots
A black fleece zip-up over a long-sleeve athletic top and fleece leggings on a cool clear day is the sporty base that works. Burgundy ankle boots break the monochrome with one precise hit of colour.
Business Casual
Camel Indigo and Belt
A camel coat over dark indigo jeans cinched with a black leather belt gives structure on a cool clear day. Black ankle boots are the straightforward finish.
