What to Wear in Denver
Denver has 300+ sunny days per year, dry air, and dramatic temperature swings. A 70°F afternoon can drop to 30°F at sundown. The altitude (5,280 ft) intensifies UV. Winter snow can melt to mud the next day. The right wardrobe is built around layers and rapid weather change.
What to wear in Denver today
Today's answer depends on today's conditions, so the specific outfit comes from the live reading for Denver rather than from this page. Check what to wear right now, or read on for what stays true here whatever the date.
Three things move the answer in Denver more than the forecast number does: the feels-like temperature rather than the air temperature, how long you will be outside, and whether you run warm or cold. Semi-arid continental conditions make that gap wider here than the daily high suggests.
Dry air means cold feels less cold than equivalent humid weather. Sunburn is a year-round risk at altitude. Always carry sunglasses and SPF lip balm. Temperature swings of 30°F in a day are normal — dress for the worst of your day.
