Figures are NOAA's official monthly climate normals for the Aspen 1 SW station (USC00050372), 1991–2020, retrieved September 28, 2026. Normals are 30-year averages: any given week can be much colder, warmer or snowier.

## The year in one chart


## A strong El Niño winter (what Aspen Privé arranges)

NOAA expects El Niño to persist through the winter, possibly at 'very strong' intensity, and its September outlook tilts most of Colorado toward above-normal precipitation. Specialist forecasters note that strong El Niño winters have historically favoured southern and eastern Colorado (the San Juans, near the Divide) more reliably than the central mountains around Aspen. It's a tilt of the odds, not a promise of snow: book for the dates that suit you, and choose flexible plans around the holidays.

- **Summer**: Warm days but cool nights: a July evening drops to the high 40s. Bring a jacket, and rain gear for afternoon storms.
- **Sun**: At nearly 8,000 feet the sun is strong year-round, and snow doubles it. Sunscreen and sunglasses in every season.
