Aspen is located at 7,908 feet above sea level giving us a high alpine climate with low humidity & year-round sunshine. 

Summer in Aspen begins in June and ends promptly Labor Day weekend when fall begins. Summer showers or thunderstorms often occur in the afternoons, but they do not last long and the rainbows are not to be believed! Temperatures during the day will reach into the 80's, but evenings are cooler so be sure to bring a sweater with you when walking around town at night. 

Fall in Aspen is very dry and daytime temperatures in September can reach into the 70's, but bundle up at night because in fall the mercury drops to freezing overnight. Peak foliage varies by year, but you are typically safe to see the golden aspens between the 3rd & 4th week of September. 

Winter in Aspen typically begins in November and lasts through April, with January having the lowest temperatures of the year. Our average annual snowfall is 300 inches and temperatures can range from 0-50 degrees Fahrenheit. The crystal clear blue sky days can often be colder than our cloudy snowy days because the clouds trap in the air circulation. 

Off-Season or Mud Season is usually mid-October - Late November & mid-April - Early June. Weather during these months is very fickle. It might snow 2 feet over night and then reach the 60's the very next day. Be prepared for all types of weather and always bring a camera. Your friends will never believe you if you tell them it is snowing on Memorial Day. 

Adjusting to High Altitude: Water is the number one way to help your body adjust to our high and dry air. You need to drink twice the amount of water here as you would at home. 

Monitor your alcohol consumption over your first few days. You will feel its affects faster than usual, so be aware & make sure to drink water as well. 

Always dress in layers when you are in Colorado. The weather can change rapidly and you want to be prepared. Also always remember sunscreen and sunglasses - you are closer to the sun at 7,908 feet above sea level! 

If you are feeling extremely ill please call 911 for medical attention.
