Best time to visit Aspen

United States · 20-year averages

Aspen is a city of two halves. June scores 92 and February scores 17 — a 75-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. Only 2 months come close to the top, which makes the timing narrow.

July is the warmest month at 26.9 °C and January the coolest at -0.9 °C — a 27.8 °C spread across the year. At the other end, 183 nights a year fall below freezing: the winter here is a real one.

There is a real wet season here. February, March, April, July and August carry the rain — up to 13 wet days in a month — while June drops as low as 5. That 8-day gap is the biggest single difference between a good month and a bad one in Aspen, and it moves further than the temperature does.

Daylight runs from 9.4 hours in winter to 14.9 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are June, September, July. The one to think twice about is February. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
